On June 1, 2017, CAPE participated in the National Bike Summit organized by Canada Bikeswhere we declared our support for the development of a National Cycling Strategy. Here is why.
A National Cycling Strategy would be a triple win for public health. It would help us to reduce the rate of chronic diseases in Canada. Chronic diseases such as diabetes and heart disease are escalating at alarming rates across the country. They place a heavy burden on the health care system while also producing pain, disability, and premature deaths for hundreds of thousands of Canadians each year. For example, cardiovascular disease alone costs $12 billion each year in Canada.
Physical activity is one of the most effective “treatments” for chronic diseases. We know that one hour of moderate to vigorous activity per week can reduce the risk of premature death by 4 to 9%. And yet, most Canadian do not get the 2.5 hours of physical activity required to maintain good health. Time—or the lack of it—has been identified as the number one barrier to physical activity.
Active modes of transportation—such as cycling—overcome this barrier. They allow people to get the “exercise” they need while travelling to work or school. One study found that people who cycle or walk to work reduce their risk of developing a chronic disease by 11%. But we know that most people, particularly women and children, will not ride to school or work unless cycling routes feel safe. Experience in other jurisdictions has demonstrated that many people will cycle for travel if they have protected bike lanes that look and feel safe.
A National Cycling Strategy would reduce acute and chronic health impacts associated with air pollution. In 2008, the CMA estimated that air pollution produces 21,000 premature deaths each year in Canada. We know these deaths are the tip of the iceberg. They represent a broad array of adverse health impacts including lung cancer, asthma, stroke, and heart disease. The CMA estimated that air pollution costs Canadians $10 billion per year in direct health care costs and lost time, and that was based on a limited number of health impacts for which the evidence was the strongest.
The transportation sector is one of the most significant sources of air pollution in Canada, particularly in large urban centres and along major traffic corridors. Modelling studies have demonstrated that we can significantly reduce air pollution, adverse health impacts, and health care costs by getting residents to use their bikes, instead of their cars, for short trips.
A National Cycling Strategy would also reduce greenhouse gases that contribute to climate change. The World Health Organization (WHO) has called climate change the most significant public health threat of the 21st century. It has estimated that 250,000 people will die prematurely each year by 2030 from climate change unless dramatic action is taken to significantly reduce our carbon emissions. Climate change is already claiming the lives of tens of thousands of people each year from heat stress, diarrhea, malaria, and malnutrition. Many of the victims are children and the elderly living in some of the poorest countries in the world. While Canadians will not experience the worst of these impacts, we are not be immune to the impacts of climate change.
Already, in Canada, we are experiencing health impacts from wild fires, floods droughts, heat waves, and severe storms that are increasing in frequency and intensity; from insect-borne diseases such as West Nile Virus and Lyme Disease that are spreading as the climate warms; and from injuries and deaths resulting from melting permafrost and shifting snow cover. The transportation sector in Canada is responsible for about one quarter of all greenhouse gas emissions. Modelling studies have demonstrated that we can significantly reduce these emissions by getting people to replace short car trips with bike trips.
A National Cycling Strategy is the holy grail of public health; the public policy the serves many public health goals with one investment. It is an investment that will pay for itself many times over in health care savings alone.
