The growing emphasis on reducing health risks through the promotion of healthy lifestyles received a further boost with the publication of A New Perspective on the Health of Canadians, more commonly known as the Lalonde Report (named after then-federal Minister of Health, Marc Lalonde, who commissioned the report).

The Lalonde Report, which is recognized as a milestone document that resulted in the international recognition of Canada as a leader in the conceptual development of health promotion, introduced the health field model, which viewed health as a product of lifestyle, biology, environment and health care organization.

In spite of the holistic nature of the health field model, the importance of lifestyle and personal responsibility for all aspects of health are emphasized throughout the Lalonde Report. For example, unhealthy practices are described as “self imposed risks” (p. 18); another section of the report notes that “individual blame must be accepted by many for the deleterious effect on health of their respective lifestyles” (p. 26).
