From The Government of Canada:

Canada’s food supply is increasingly global in nature and many Canadians are seeking clearer information about the foods they buy. Recognizing this, the Government of Canada is taking action to improve the labelling information on food products and to help Canadians make better purchasing decisions.

Following the launch of the Healthy Canadians website on October 24th, 2007, Prime Minister Stephen Harper announced Canada’s Food and Consumer Safety Action Plan on December 17th, 2007, with the goal of ensuring Canada’s product safety standards are second to none.

As part of the Food and Consumer Safety Action Plan, the Government committed to reviewing the policy on the use of “Product of Canada” and “Made in Canada” claims on food labels and advertising.

Prime Minister Stephen Harper delivered on this commitment on May 21, 2008, by unveiling the new Canadian Food Labelling Initiative together with Gerry Ritz , Minister of Agriculture and Agri-Food Canada. The new Canadian Food Labelling Initiative improves the definition of “Product of Canada” and “Made in Canada” on food labels and advertising, to ensure that Canadians can be more clear about the food products they purchase. These proposed guidelines are outlined in the Discussion Paper found on this page.
