Re: Future Mandate of the Health Care Innovation Working Group (the Council of the Federation)
On behalf of the Canadian Nurses Association (CNA) and the Canadian Medical Association (CMA), I am writing in advance of the meeting of the Council of the Federation later this month regarding the future mandate of the Health Care Innovation Working Group with respect to seniors care.
The CNA and CMA welcomed the Council of the Federation's prioritization of seniors care as an area of focus of the Health Care Innovation Working Group. Already, seniors and their families in communities across Canada face significant challenges accessing social supports and health services. These challenges will only intensify as the demographic shift progresses. Based on current trends and approaches, the proportion of provincial/territorial health spending associated with seniors care is forecast to grow by over 15% to almost 62% of health budgets by 2036.
Recognizing the significant pressure this will present for health care systems and provincial/territorial budgets moving forward, it is critical that the Council of the Federation maintain its prioritization of seniors care and meeting the needs of an aging population. As such, we respectfully encourage you in your capacity as Co-Chairs of the Health Care Innovation Working Group to ensure the future mandate of the working group on seniors care be included as part of the agenda at the January 30, 2015 meeting of the Council of the Federation.
The CNA and CMA are actively engaged on this issue and welcome the opportunity to meet with each of you to discuss how we may collaborate to ensure improved health outcomes for seniors, now and in the future.

The Canadian Medical Association (CMA) supports the promotion of healthy lifestyles in order to improve individual health and well-being and the overall health status of the population. Healthy lifestyles refer to patterns of individual practices and personal behavioural choices that are associated with optimal health. Two of the most important behaviours to create or maintain optimum health are healthy eating and physical activity.
For many Canadians, their diet and physical activity levels can have a negative rather than positive impact on their overall health. There is a particular concern for children and youth who are growing up in increasingly obesogenic environments that reinforce practices that work against a healthy lifestyle.1 Childhood obesity research tells us that overweight and obese children are more likely to stay the same into adulthood.2 To reverse this trend, determined action is required for children and youth to learn and acquire healthy behaviours that they will maintain throughout their life. Healthy lifestyles are central to successful aging and improving the likelihood of recovery after poor health.3
This policy paper discusses the importance of physical activity and healthy eating, and the role that individuals and families, schools, workplaces, communities, the food industry and all levels of governments can play in promoting healthy lifestyles. We know that collaborative action is required to make it easier for Canadians to incorporate healthy eating and physical activity into their daily lives - to make the healthy choice the easy choice.
What are the health impacts of unhealthy diets and physical inactivity
Diet is the leading risk factor for death, disability and life-years lost; being estimated to cause over 65,000 deaths and 864,000 life years lost in Canada in 2010.4
Unhealthy diet has been consistently linked with cardiovascular diseases (heart disease, stroke, hypertension, diabetes, dyslipidemia) and some cancers,5 which constitutes the majority of the disease burden in Canada. An estimated 80% of hypertension, which affects over 7 million Canadians, is directly or indirectly attributed to unhealthy diet.6
An estimated 60% of Canadian adults and close to one-third of children are overweight or obese, largely caused by unhealthy diets.7 Overweight and obesity (and the lifestyle choices associated with them) are contributors to more than 18 chronic conditions.8 This includes diabetes, cardiovascular disease, hypertension and liver disease, as well as breast, colon and prostate cancer.
Obesity is a public health issue not unique to Canada as the rates are increasing worldwide. Obesity is generally attributed to the fact that, as a society, we are increasing our calorie intake while at the same time burning less energy in physical activity. While it is difficult to determine how many deaths are directly attributable to obesity, we know that obesity often co-exists with other risk factors such as the lack of physical activity.
Exercise is one of the top modifiable risk factor for chronic disease.9 Regular physical activity is associated with a reduced risk of cardiovascular disease, some types of cancer, diabetes, obesity, hypertension, bone and joint diseases, and depression.10 The risk for many of these conditions is reduced by 20 - 40% in adults with the highest levels of physical activity compared to those with the lowest levels of physical activity. Recent research has shown that a sedentary lifestyle is associated with higher risk for chronic conditions such as obesity, diabetes and cancer independent of physical activity levels.11
According to the most recent Canadian Health Measures Study physical activity levels for children and youth are low with 6 out of 10 waking hours devoted to sedentary pursuits. Obesity is rising and physical fitness is declining.12
Canadians who do not achieve adequate levels of physical activity or eat unhealthy foods are vulnerable to preventable chronic diseases, premature death, and contribute to high health care costs. For instance, in 1999, $2.1 billion or 2.5% of the total direct health care costs were attributable to physical inactivity.13
To understand why the rates of obesity and overweight are rising, it may be helpful to look at what we already know about healthy eating and physical activity.
What we know about healthy eating
While modern science has allowed us to expand our knowledge of the impact of nutrients and food on human health we continue to be beset with illness and disease caused by the foods we consume. Having the right amount and type of food recommended in Canada's Food Guide is a first step towards healthy eating. But Canadians self-reported dietary intakes do not meet national dietary recommendations despite high reliance on public education concerning healthy eating and healthy diets. Children and adults are under-consuming the recommended servings of vegetables and fruits, an established proxy for healthy eating habits, and exceeding daily recommended intakes of sodium.14,15
As the links between nutrition and disease, and the impact on the health of our society are revealed it is more important than ever to understand what influences healthy eating behaviours. Food choices are structured by a variety of individual determinants of behaviour, ranging from one's physiological state, food preferences, nutritional knowledge, perceptions of healthy eating and psychological factors.
Many processed foods have become popular due to their accessibility and 'convenience factor', but these features have changed the way food and in particular these products are consumed compared to unprocessed foods: increased 'grazing', eating alone or eating while carrying out other activities such as work or driving. In addition, many calories consumed come in liquid form.16
Growth in the production and consumption of ultra-processed foods has increased drastically in the last decades in both higher and lower-income countries.17 A number of studies have shown that because less healthy foods are cheaper than healthier food, individuals from lower socioeconomic classes tend to be more dependent on unhealthy foods for nourishment.18
Other determinants for healthy eating include a wide range of contextual factors, such as the interpersonal environment created by family and peers, the physical environment, which determines food availability and accessibility, the economic environment, in which food is a commodity to be marketed for profit, and the social environment. Within the social environment, social status (income, education and gender) and cultural milieu are determinants of healthy eating that may be working "invisibly" to structure food choice.19
What we know about physical activity
Canada's Physical Activity Guidelines recommend that children and youth aged 5 to 17 get at least 60 minutes of moderate-to-vigorous physical activity (MVPA) per day; and adults get 150 minutes of physical activity per week.20 In fact, about 94% of Canadian children and youth do not meet minimum physical activity guidelines.21 Furthermore, about 85% of Canadian adults do not meet the minimum guidelines. Physical activity includes but is not limited to sports and recreation. Using active transportation to get to work as well as being active at work is an alternative form of MVPA and can also lead to improved health.
For most Canadians, the average day is spent on passive activities such as TV viewing, computer and game-console use, workplace sitting, and time spent in automobiles. Moreover, the sprawling suburban communities, in which many live, do not encourage physical activity.
Emerging research suggests that prolonged sitting time is associated with an increased health risk.22 These findings mean that one can meet the minimum physical activity guidelines and still not engage in a healthy lifestyle. Spending a few hours a week at the gym or otherwise engaged in moderate or vigorous activity doesn't seem to significantly offset the risk. Hence too much sitting is a risk distinct from too little exercise.
While further research is required to identify which methods of exercise promotions work best for individuals,23 it is clear that supportive environments and infrastructures are essential for Canadians to make physical activity part of their daily lives. CMA's policies about the Built Environment and Active Transportation support the role of the environment on our physical activity patterns.
How we can promote physical activity and healthy eating
A sedentary lifestyle is a cue for physician advice.24 Physical activity is a vital sign that may require as much attention as other traditional vital signs25 - weight, blood pressure, or smoking history. Physicians are eager to initiate these conversations, especially with patients living with chronic diseases. A message must be repeated many times in order to effect a change in lifestyle. Physicians can reiterate the medical importance of physical activity and healthy eating by reinforcing this message during each office visit, and writing the recommendation on a prescription pad.26 For instance, in British Columbia, physicians are prescribing exercise on specially-designed pads, distributing free pedometers, and hosting free walking events for their patients and the public. In the Edmonton area, Primary Care Networks are prescribing free access passes or a free month of access at local municipal recreation facilities. And in Nova Scotia, physicians have been running a free provincial running program for over 10 years that benefits thousands of kids in elementary school.
Nonetheless these clinical interventions alone cannot shape healthier food consumption patterns and lifestyle choices. An obvious starting point to develop a comprehensive policy is to understand the interplay between individual and environmental determinants that influence our behaviours. In this regard, CMA has developed policies on Active Transportation and the Built Environment and Health which recognize the role of neighborhood design and alternative modes for transportation for an active lifestyle. This approach is also at the heart of the Integrated Pan-Canadian Healthy Living Strategy (PCHLS)27, approved in 2005 by all levels of government. CMA commends the efforts put in the PCHLS to prioritize healthy eating and physical activity.
What we recommend
CMA looks forward to working with others in making options for physical activity and healthy eating more available and accessible to all Canadians. The following recommendations highlight the potential contributions of the following sectors: health professionals, all levels of government, communities, workplaces, schools, the food industry and individuals and families.
CMA encourages physicians to promote healthy eating and physical activity inside and outside their office.
Physicians are lifestyle change agents and remain the preferred source of information about health for many people. Physicians, who are committed to physical activity, are role models whose advice on healthy living is more likely to be adopted.28 CMA encourages physicians to address any work-imposed limitations - such as the lack of time, motivation, or tiredness - that could also influence their own exercise and eating habits.
In clinical practice, physicians can help patients start or maintain a healthy lifestyle by:
* assessing nutrition and physical activity as part of routine assessments;
* determining the factors that influence individual patient's nutrition and physical activity levels;
* assessing patient's readiness to change and tailoring interventions and support to their current situation;
* providing an exercise prescription to encourage physical activity to maintain or improve health status, and
* working in inter-professional teams to provide patient education with other health care providers such as dieticians.
Medical students and residents, while reporting a high level of importance for exercise prescription concede a low level of expertise in this area upon graduation.29,30,31 As knowledge develops, physicians and other health professionals should be kept updated and encouraged to incorporate the most effective interventions into their practices. The CMA encourages the development of continuing medical education courses on issues related to physical activity and healthy eating.
Within the healthy living approach, there are multiple opportunities to extend the role of physicians into the community as observed in Nova Scotia, British Columbia and Edmonton area. Physicians can establish strong community norms for a healthy lifestyle by:
* establishing and reinforcing healthy food policies in hospital cafeterias or at health-related meetings and conferences
* using, facilitating and advocating for the use of active transportation in their communities
* working within the community to ensure that recreation centres and other facilities are available and patients can be referred to the services most appropriate to their needs
Federal, Provincial, and Territorial Governments
CMA calls on federal, provincial, territorial and municipal governments to commit to a long-term, well-funded Canada-wide strategy for healthy living beyond 2015.
In 2005, Canada's federal, provincial, and territorial governments endorsed a 10-year Healthy Living Strategy Framework, whose initial priorities included the promotion of healthy eating and physical activity. The national strategy addressed information and support for Canadians to help them make healthy choices; support for physicians and other health professionals in counselling patients on healthy weight and in treating existing obesity; community infrastructures that make healthy living easier; and public policies that encourage healthy eating and physical activity. The federal and provincial / territorial governments have undertaken a number of activities in the intervening years to promote physical activity and healthy eating but much remains to be done.
CMA believes that all levels of governments have a continuous obligation to provide public guidance on healthy eating and to promulgate policies, standards, regulations and legislations that support the availability and accessibility of healthy and affordable food and beverage choices.
CMA calls on governments to improve access to nutritious food at affordable prices for all Canadians.
The price of milk, fresh produce and other healthy foods can vary greatly across Canada. In many remote areas, they are often more expensive than processed, nutrition-poor foods because of high transportation costs. Governments should implement effective programs to offset the impact of transportation costs on food prices in northern and remote communities. Even in urban areas, nutritious food may be unaffordable for people on low incomes. School meal programs, social assistance rates that take into account the cost of purchasing healthy food, access to urban farmers' markets can help to ensure that all Canadians have access to healthy foods at a reasonable price.
CMA calls on governments to ban marketing of foods and beverages high in salt, sugars and trans fats to those 13 years of age and younger.
The typical Canadian child may be exposed to as many as 40,000 advertisements for food a year.32 This does not include point-of-sale promotions, such as displays of candy bars at convenience-store counters. CMA's policy on marketing of unhealthy foods and beverages to children and youth calls for a ban on marketing of foods and beverages high in salt, sugars and trans fats to those 13 years of age and younger.
CMA calls on governments to set rigorous standards for front of package food labeling and for the advertising of health claims for food.
Brand-specific advertising is a less than optimal way to provide health information to consumers, who should be encouraged to seek out objective information sources for answers to their questions about physical activity and healthy eating. To improve the quality of information received through commercial channels, the CMA recommends that health claims made for foods be strictly regulated to ensure that they are based on the best available scientific evidence and that they are accurately communicated to consumers. Food advertisements should be pre-cleared before airing in the media, and the provisions against deceptive advertising in the Food and Drug Act should be strengthened.
CMA recommends that governments at all levels invest in evidence-based research on healthy eating and physical activity and share the results of this research with all Canadians.
CMA encourages all levels of governments to continue to fund and support research for healthy lifestyles. There is a clear need to invest in research to strengthen the evidence base about physical activity and healthy eating, particularly on:
best measures for assessing overweight and obesity;
the effectiveness of weight management and treatment programs; and
the effect of policy interventions on healthy eating and physical activity on rates of obesity and obesity-related disease.
CMA encourages governments to continue to work with the food industry to improve the food environment in Canada.
The partnership and collaboration of food manufacturers is needed to help Canadians make healthier food choices. The food industry can work with governments to:
reduce the salt, sugar, saturated fat, trans fat and calorie content of processed foods and pre-prepared meals;
provide information about the calorie and nutrition content on restaurant menus;
restrict advertising and in-store promotion of high-sugar, high-salt, high-fat foods, particularly those aimed at children;
provide user-friendly consumer information about their products, including and accurate health and advertising claims;
improve the nutrition fact table to make it more user friendly and increase the amount of information for example, by identifying the amount of free sugars.
CMA calls on municipal governments to create environments that encourage healthy and active living and on federal, provincial and territorial governments to support them in this endeavour.
Communities have an important role to play to promote healthy behaviours for children, youth, and adults. They shape how many Canadians decide to live, work and play in their daily life. Through mixed-use land planning and building design, communities can create walking-friendly environments, and reduce the time people spend in cars. To achieve this, communities should consider:
developing and maintaining a community-wide network of walking and cycling paths;
zoning communities in such a way that amenities are within walking distance of homes; and
revising building codes to make stairs accessible, pleasant and safe, so that people have an alternative to taking the elevator.
Canadians are considerably more physically active in the summer than in the winter and this could have an impact on obesity trends.33 Communities could improve pathways to healthy lifestyles year-round by improving access to indoor sport and recreation facilities, especially during winter. Where possible, communities should consider partnering with schools to share the use of gymnasiums, playgrounds, fields, courts, and tracks with the public after school hours and on weekends. In doing so, communities are ensuring the best use of time and resources, but also sharing liability for the development, operation, and maintenance of the facilities.
Community food security can happen if local residents have equal access to safe, affordable and nutritious food. Communities have a role to play in advocating for healthier food options in schools and workplaces, encouraging community kitchens to teach cooking skills, and supporting local agriculture and farmers markets. This, in turn, would encourage individuals to eat more healthy foods.
CMA encourages employers to actively promote the health of their employees by providing opportunities for physical activity, and healthy food choices in cafeterias.
Prolonged, unbroken time spent sitting in front of a screen is very common in the workplace. In addition, four out of five commuters sit daily in their private vehicles to go to work.34 As Canadians spend most of their adult life at work, it is important to reduce workplace sitting. CMA encourages employers, especially in sedentary occupational groups, to increase opportunities for physical activity. For example, employers can promote healthy behaviours by:
Building on-site fitness facilities or entering into agreements with off-site fitness centres to provide programs for their employees
Providing showers, bike racks and other amenities for employees for those who want to commute to work on foot or by bike.
Healthier food options in cafeteria and vending machines can promote and encourage healthy eating by employees.
Schools, where children spend most of their time outside of home, present an excellent opportunity to instil healthy behaviours at an early age. They could, for example, provide comprehensive nutrition education, serve nutritious food in their cafeterias and promote physical activity by providing formal instruction and informal recreation time. Schools can provide the most effective and efficient way to reach not only the children themselves, but their parents, teachers, and other community members.35
CMA encourages school boards to provide at least 60 minutes of active daily physical education for all primary and secondary grades.
Only 26% of Canadian schools reported that they had implemented daily physical education classes for their students.36 There is some evidence that school-based physical activity can increase physical activity levels and reduce time spent watching television at home. 37 For instance, schools can promote physical activity through unstructured out-of-home play, structured sports, or active transportation (e.g. walking to school). Children who are physically active and spend less time watching television after school are less likely to become overweight before age 12.38
CMA recommends that schools provide access to attractive, affordable, healthy food choices, provide nutrition education, and initiate programs aimed at encouraging healthy food consumption and skills to prepare meals from scratch.
CMA calls for restrictions on the sale of high-calorie, high fats, sugars or salts foods/drinks in recreational facilities frequented by young people.
Fast food restaurants and convenience stores can be an important influence on children's eating habits and food choices.39 Children attending schools within a short distance of fast food restaurants eat fewer fruits and vegetable servings, and drink more soft drinks than others who did not have similar establishments within proximity.40 To encourage effective school-based nutrition interventions, it is therefore important to educate students about the nutrition value of foods, healthy food choices, and provide healthy canteens or cafeterias.
Individuals and families
CMA recommends that all Canadians work toward achieving and maintaining health by:
educating themselves about their dietary needs and about the caloric and nutrition content of foods; and
engaging in physical activity, with the goal of at least 60 minutes of moderate activity per day for children and youth, and 150 minutes per week for adults.
Ultimately, healthy eating and physical activity require that individuals take action to make healthy choices in their lives. To inform these choices, Canadians should be supported with appropriate resource materials with consistent information about healthy eating and physical activity. For instance, many young children do not choose what they consume; their parents buy and prepare the food for them. Research suggests that mothers and children appear to have divergent attitudes towards food and mealtimes.41 In this regard, it is important for parents to be well-informed and able to explain the tangible benefits of foods and their nutritional components to their children before they reach adulthood.
What we conclude
Healthy behaviours are easier to maintain through life if acquired in childhood and encouraged by the family. Therefore Canadian families should be supported in efforts to ensure that both children and adults eat nutritiously and exercise daily. We believe there is a role for everyone in promoting healthy behaviours - including health professionals, individuals, families, schools, workplaces, communities, the food industry and all levels of governments.
Popular approaches seek to provide individuals with information and options about healthy lifestyles choices. However, individual choice is not sufficient to ensure healthy behaviours.
Many barriers to the adoption of healthy behaviours and lifestyle choices can be met through a targeted population health approach, and evidence-based policy and regulatory controls. A comprehensive change in culture and mindset, political endorsement and multifaceted strategies are needed to promote and facilitate change to improve the dietary practices and physical activity levels of Canadians.

The Canadian Medical Association (CMA) would like to thank the Standing Senate Committee on Social Affairs, Science and Technology for the opportunity to provide our views on the causes and consequences of obesity in Canada, and our recommendations for a way forward.
Canada’s physicians have repeatedly expressed their concern about the increasing prevalence of obesity and overweight in this country. Over the past ten years, responding to these expressions of concern, the CMA has developed a number of policy statements, briefs to government, and discussion papers on the issue, which articulate our recommendations for addressing this serious problem. In this brief, we will focus our recommendations on two remedies that we believe should be part of the way forward: the implementation of public policy that supports Canadians in making healthy food choices; and the provision of reliable, user-friendly information to health professionals and to the public.
2) Obesity in Canada: Causes and Consequences
More than half (62%) of Canadian adults are overweight according to the 2013 Canadian Health Measures Survey. A quarter of Canadian adults can be classed as obese (BMI = 30); this is double the obesity rate in 1979.1 The rise in obesity is most pronounced among Canada’s heaviest people; since 1985, the prevalence of extreme obesity (BMI=40) rose from 0.3% to 1.6%, a more than five-fold increase.2 One in ten Canadian children is obese;3 obesity in children and youth has more than doubled since the late 1970s. Prevalence of overweight and obesity is higher among some segments of the Canadian population, particularly Aboriginal peoples and people of lower socio-economic status.

Obesity is of particular concern to Canada’s physicians because it increases a person’s risk of developing a number of serious health problems: high blood pressure, high blood cholesterol, heart disease and stroke, type 2 diabetes, osteoarthritis, lower back pain and other musculoskeletal disorders, and many types of cancer. Type 2 diabetes, once found only in adults, is now being seen in children4. Health advocates are concerned that because of obesity, today’s generation of children will have a shorter life expectancy than their parents.
In addition to poor physical health, obese people are at greater risk than people with normal weights of suffering from mental health problems such as low self-esteem, depression and anxiety. The stigma attached to obesity is high; obese people are at high risk of being bullied, ostracized socially, and discriminated against in the workplace. Some turn to food to relieve stress or as an escape from their unhappy lives, thereby perpetuating a vicious cycle of unhealthy eating and poor mental health.5

7 From the CMA background paper on processed food and health. Original citation: Cohen D a. Obesity and the built environment: changes in environmental cues cause energy imbalances. Int J Obes (Lond). 2008;32 Suppl 7:S137–42. doi:10.1038/ijo.2008.250.
The Public Health Agency of Canada estimates that obesity-related health conditions cost Canada $4.6 billion dollars in 2008, both in direct costs (such as hospitals and health professional services) and indirect ones (e.g. disability claims, psychological damage and lost productivity).6 Other estimates have been even higher.
The causes of obesity are multifarious and highly complex. There is no one, simple cause. In some cases human biology is responsible, because certain people have a genetic predisposition toward gaining weight. But for the most part, obesity can be attributed to environmental circumstances that contribute to Canadians consuming more calories than they burn through physical activity. These circumstances include:
. The widespread consumption of pre-packaged and processed foods. In the US it is estimated that the percentage of food spending that goes toward foods prepared away from home went up from 24% in 1966 to 42% in 2006.7 Processed foods are more likely than fresh foods to be high in trans fats, sodium, sugar and other ingredients that are risk factors for obesity-related diseases. They are available widely, in fast-food outlets, grocery stores and vending machines, and their manufacturers often promote them heavily. In addition, they are generally lower in price than fresh fruits, vegetables or meats, which may be beyond the means of many low-income Canadians.
. Change in physical activity patterns. Many adults spend their days at sedentary desk jobs, and if they engage in physical activity, they often devote specific time to it (say, an hour at the gym) rather than incorporating it into their daily lives. Where children might once have gone outdoors to play after school, today they are more likely to sit in front of a computer or television set.
The conventional wisdom about addressing obesity is that it is the individual’s responsibility to lose weight through diet and exercise, and to keep it off. However, achieving and maintaining a healthy weight is a complex process, and can be frustratingly hard to manage. For many Canadians, obesity is a lifelong condition, and the environmental conditions discussed above
discourage healthy behaviour. Despite an abundance of diet information and advice (of varying quality and accuracy), most people who lose weight eventually put it on again. Pharmaceutical weight loss drugs are available but are not always recommended because of their side effects8. More aggressive treatments such as surgery are recommended mainly for severely obese people with health complications.

3) The Way Forward
Just as obesity sparks challenges in our populations and has no single cause, so there is no single way forward that will fully address it. CMA believes that the way forward actually involves a number of separate paths moving in the same direction. Two of these paths are discussed in the following sections.
a) Implementing Public Policy That Helps Canadians Make Healthy Food Choices
Public policy can be a powerful tool to help reduce risks to public health. In the case of tobacco control, measures such as bans on tobacco advertising and on smoking in public places contributed to the decline in smoking in Canada by making it easier for individuals to choose to be smoke-free. In the same way, CMA believes the federal government should implement policies and regulations to help create a supportive environment for people wanting to achieve and maintain a healthy weight. In particular, CMA recommends that the Committee give consideration to the following measures:
i) Improving Access to healthy food
Recommendation: that the Government of Canada support community-based initiatives aimed at reducing Canadians’ barriers to accessing healthy, nutritious food.
If Canadians are to be encouraged to make healthy food choices, then healthy foods should be readily available to them at affordable prices. Unfortunately, for many Canadians, this is not the case. In some neighborhoods, often lower-income neighbourhoods, fast food outlets outnumber grocery stores. Many variety stores, restaurants, schools and workplace cafeterias offer a larger selection of processed foods than of fresh fruits, vegetables and meat.
For some Canadians, financial barriers limit their capacity to make healthy individual choices. As a rule, fresh food tends to be more expensive than processed “fast food”. The difficulty is
compounded in Canada’s remoter areas and in the North, where fresh produce must be transported from far away, and what little is available is very high priced.
Programs to improve access to healthy food exist at all levels of government. The federal Northern Food Program, designed to offset the cost of transporting fresh food to remote areas, has been in existence for several years, though it has been criticized as ineffective9. At the community level, not-for-profit and municipal agencies have collaborated on programs such as the Good Food Markets in Ottawa, which offer fresh, affordable foods in low-income areas.10

11 “Restricting Marketing of Unhealthy Foods and Beverages to Children and Youth in Canada” a policy paper endorsed by CMA and other health and scientific organizations.
Other measures to improve access to healthy food could include: ensuring that every Canadian is within reach of a grocery store; regulating the number and location of fast-food outlets; and increasing the availability of nutritious foods and restricting that of processed foods in workplaces, schools and recreational facilities.
ii) Controls on Marketing of Processed Foods.
Industry marketing of fast food and processed food, including beverages, is ubiquitous – in television, on the radio, on the Internet, and at point-of-purchase displays and event sponsorships. Unfortunately, many of the advertised foods are high in calories and low in nutrients. Food advertising is aimed at Canadians of all ages, but children, particularly those under the age of 13, have been found to be especially vulnerable to it. Research has shown that the advertising of food and beverages to children influences their food and beverage preferences, purchase requests and consumption patterns.11
At present, Canada relies on voluntary industry codes to govern advertising and marketing practices. However, health groups are skeptical of the effectiveness of such codes, and of manufacturers’ commitment to them. The CMA believes that for maximum efficacy, regulatory measures are required to minimize the negative effect of food marketing on health.
Recommendation: That governments ban the advertising and promotion of high-calorie, nutrient poor foods to children 13 years of age or younger.
Food advertisements often include claims as to the product’s nutrition content and health benefits. Unfortunately, such advertising may be misleading; a product labelled “lower fat” may
still have a relatively high fat content, or contain high levels of other potentially unhealthy ingredients such as sugar and sodium. In general, brand-specific advertising is a less than optimal way to provide health information to consumers. Therefore, CMA believes that the federal government should review and regulate the health claims that manufacturers can make for their products, to ensure that these claims are based on the best available scientific evidence and that they are accurately communicated to consumers.
Recommendation: that the Government of Canada set rigorous standards for the advertising of health claims for food, and strengthen provisions against deceptive advertising in the Food and Drug Act.
iii) Enhancing Nutrition Labelling
Governments at all levels, as well as health organizations, currently provide a variety of programs, educational materials and guidelines to the public. The CMA encourages these initiatives and encourages all levels of government to continue to make overweight and obesity a public health education priority.
Food labels are an important means of health education, providing guidance to shoppers at the point of purchase to help them inform their food choices. Health Canada has made important contributions to public education, through a number of programs including its “Nutrition Facts” package labels. The labels are continually being revised and updated, as research reveals new information about nutrition and about effective means of conveying health messages to the public. As part of its revision process, CMA believes that Health Canada should consider enhancing health messages on the front as well as the back of food packages.
Recommendation: that the Government of Canada implement, and set rigorous standards for, front-of-package food labelling.
The CMA encourages the federal government to build upon the current package labelling system, making labels as user-friendly as possible and helping Canadians to interpret the information they provide. Colour-coded, brief-summary labels, such as the “red-light, green-light” system used in Britain, are intended to provide consumers with an “at a glance” assessment of a food’s nutritional value. While the system has its critics, it has the benefit of being easy to notice and interpret. The CMA has also recommended that food packages and retail displays contain warnings about the health risks associated with an excessive consumption of calorie-high, nutrient poor food and beverages.
b) Information and Support for Physicians and other Health Professionals
For many patients, obesity is a lifelong condition which, like other chronic health conditions, can be managed medically but rarely fully cured. Increasingly, it is being recognized that effective obesity management requires more than short-term weight loss diets; it involves identifying and addressing both the root causes of a patient’s weight gain (physical, psychological or socio-economic) and the barriers the patient experiences in maintaining healthy weight. 12 According to the Canadian Obesity Network, primary care interventions should be evaluated not by how many pounds the patient loses but by improvements in the patient’s health and well-being.

Physicians, working with dietitians, nurses, physiotherapists, mental health care providers and other health professionals, have an important role in providing care and support to people who are trying to maintain a healthy weight. Physicians can provide nutrition advice to patients as part of the routine medical examination. In addition, since primary care physicians are generally the patient’s first point of contact with the health care system, they often see patients at “teachable moments” when, because of an associated health condition such as diabetes, they are motivated to change unhealthy behaviours. Physicians can also provide patients with resources to help them live healthy lives. For instance, in British Columbia, physicians are prescribing exercise on specially-designed prescription pads, distributing free pedometers, and hosting free walking events for their patients and the public. In the Edmonton area, Primary Care Networks are prescribing free access passes or a free month of access at local municipal recreation facilities.
The tertiary health care sector also has an important role to play in addressing obesity, since there is a growing number of severely obese patients who are at high risk of serious health problems and may require specialized treatment, possibly bariatric surgery. According to a study by the Canadian Institute for Health Information, the number of bariatric surgeries performed in Canada has jumped four-fold since 2006-07. The study notes that though the health care system has made great strides in meeting the demand,13 access to bariatric surgery varies from one region of Canada to another. Governments have an important role to play in ensuring equitable access to bariatric surgery for patients for whom it is clinically indicated.
Recommendation: That the federal government work with provincial/territorial governments and with researchers, medical educators and others to continually develop and disseminate up-to-date, evidence-based clinical knowledge and
practice tools, to help physicians and other health professionals manage overweight and obesity in their patients.
Clinical guidelines, based on the best current scientific evidence, are available to help health professionals work with their patients to achieve and maintain healthy weights. The Canadian Obesity Network has developed a “5As of Obesity Management” program for primary care. The Canadian Task Force on Preventive Health Care also develops and frequently updates recommendations for primary caregivers on how to manage overweight and obesity in practice. The Task Force’s most recent recommendations were published in the Canadian Medical Association Journal early in 2015. Clinical practice guidelines should be distributed widely and continually updated, and governments could play an important role in supporting the revision and dissemination process.
Thanks to ongoing research our knowledge of the extent and causes of obesity, and the effectiveness of existing programs in addressing it, is continually growing and developing. CMA encourages an ongoing commitment to research, and believes that the Government of Canada has an important role to play in supporting it. Results of this research should be communicated to health professionals and the public as quickly and widely as possible, so that it can be rapidly incorporated into clinical practice.
Recommendation: That the federal government support, and help to disseminate, evidence-based research on obesity in Canada and on the evaluation of strategies to address it.
Obesity and overweight are serious health problems in Canada, and as such are of great concern to the country’s physicians and to the Canadian Medical Association. The causes, CMA believes, are rooted mainly in changes in our environment and their effect on our eating and physical activity habits. The consequences are extremely serious, both for individual Canadians’ health and for the sustainability of Canada’s health care system.
CMA believes that the way forward requires a number of different interventions, on many levels. These should include providing and continually updating research and practice information for health professionals; and implementing policies that support Canadians as they pursue the goal of maintaining healthy weights.
Once again, CMA commends the Senate of Canada on conducting this study. We hope it will help encourage productive and meaningful change in the way Canadians view obesity, and assist in creating a social environment that supports healthy eating and healthy weight.
The Canadian Medical Association (CMA) is pleased to present this brief to the House of Commons Standing Committee on Finance regarding Bill C-462 Disability Tax Credit Promoters Restrictions Act.
The Canadian Medical Association represents 78,000 physicians in Canada; its mission is to serve and unite the physicians of Canada and to be the national advocate, in partnership with the people of Canada, for the highest standards of health and health care.
The CMA is pleased that the House of Commons has made Bill C-462 a priority. This bill is an important step toward addressing the unintended consequences that have emerged from the Disability Tax Credit since 2005.
Part 2: Issues to be addressed
In 2005, the Disability Tax Credit was expanded to allow individuals to back-file for up to 10 years. While this was a welcome tax measure for individuals with disabilities, the CMA has been urging the Canada Revenue Agency to address the numerous unintended consequences that have emerged. Central among these has been the emergence of a “cottage industry” of third-party companies engaged in a number of over-reaching tactics. The practices of these companies have included aggressive promotional activities to seek and encourage individuals to file the Disability Tax Credit. The primary driver behind these tactics is profit; some companies are charging fees of up to 40 per cent of an individual’s refund when the tax credit is approved.
Further to targeting a vulnerable population, these activities have yielded an increase in the quantity of Disability Tax Credit forms in physician offices and contributed to red tape in the health sector. In some cases, third parties have placed physicians in an adversarial position with their patients. We are pleased that this bill attempts to address the concerns we have raised.
The CMA supports Bill C-462 as a necessary measure to address the issues that have emerged since the changes to the Disability Tax Credit in 2005. However, to avoid additional unintended consequences, the CMA recommends that the Finance Committee address three issues prior to advancing Bill C-462.
First, as currently written, Bill C-462 proposes to apply the same requirements to physicians as to third-party companies if physicians apply a fee for form completion, a typical practice for uninsured physician services. Such fees are subject to guidelines and oversight by provincial and territorial medical regulatory colleges (see Appendix 1: CMA Policy on Third Party Forms: The Physician Role).
The CMA recommends that the Finance Committee:
Amend the definition of “promoters” under section 2 to exclude “a health care practitioner duly licensed under the applicable regulatory authority who provides health care and treatment.”
. If the committee imports the term “person” from the Income Tax Act, then the applicable section of Bill C-462 should be amended to specify that, for the purposes of the act, “Person does not include a health care practitioner duly licensed under the applicable regulatory authority who provides health care and treatment.”
Second, the CMA is concerned that one of the reasons individuals may be engaging the services of third-party companies is a lack of awareness of the purpose and benefits of the Disability Tax Credit. Additional efforts are required to ensure that the Disability Tax Credit form (Form T2201) be more informative and user-friendly for patients. Form T2201 should explain more clearly to patients the reason behind the tax credit, and explicitly indicate there is no need to use third-party companies to submit the claim to the CRA.
The CMA recommends that the Finance Committee:
. Recommend that the Canada Revenue Agency undertake additional efforts to ensure that the Disability Tax Credit form is more informative, accessible and user-friendly for patients.
Finally, the CMA recommends that a privacy assessment be undertaken before the bill moves forward in the legislative process. It appears that, as written, Bill C-462 would authorize the inter-departmental sharing of personal information. The CMA raises this issue for consideration because protecting the privacy of patient information is a key duty of a physician under the CMA Code of Ethics.
Part 3: Closing
The CMA encourages the Finance Committee to address these issues to ensure that Bill C-462 resolves existing problems with the Disability Tax Credit while not introducing new ones. The CMA appreciates the opportunity to provide input to the Finance Committee’s study of this bill and, with the amendments outlined herein, supports its passage.
Summary of Recommendations
The definition of “promoters” under section 2 of Bill C-462 should be amended to exclude “a health care practitioner duly licensed under the applicable regulatory authority who provides health care and treatment.”
If the Committee imports the definition of “persons” from the Income Tax Act, the applicable section of Bill C-462 should be amended to specify that, for the purposes of the act, “Person does not include a health care practitioner duly licensed under the applicable regulatory authority who provides health care and treatment.”
The Canada Revenue Agency should undertake additional efforts to ensure that the Disability Tax Credit form is informative, accessible and user-friendly.
Prior to advancing in the legislative process, Bill C-462 should undergo a privacy assessment.
