Miracle Food Mart was a supermarket chain in Ontario, Canada, owned by Steinberg's, a Quebec-based retailer in the 1970s and 1980s.

This move proved to be successful as the chain expanded quickly (to approximately 80 stores) over the next ten years, gaining a substantial increase in market share.

In 1973, the Miracle Food Mart division made a revolutionary move to abolish its general-image advertising and to mount a "give-'em-the-facts" consumer-oriented campaign.

The program included a formal Consumer Bill of Rights, nutrition booklets, a key to the codes used to mark perishables, and clearly labelled price tags.

The supermarket flourished in the 1970s, and expanded with the Miracle Ultra Mart banner into bigger stores with a wide range of health care and general merchandise.
