Knob Hill Farms was a supermarket chain in the Greater Toronto Area, Ontario, Canada that operated from 1953 to 2001 and was owned by businessman Steve Stavro.

Knob Hill Farms began as a small east Toronto fruit stand in 1951, operated by Steve Stavro, his brother Chris and their father.

[1] In 1963, Stavro changed direction and opened his first "food terminal"—a forerunner of the big-box store with 60,000 square feet (6,000 square-metres) of space just north of Toronto at Woodbine Avenue and Highway 7 in Markham.

The terminal was located at Lansdowne Avenue and Dundas Street West, on a site previously occupied by a National Cash Register plant.

The site was previously an industrial building dating back to the 1930s and was used for the assembly of aeroplanes (de Havilland Mosquitos) by Massey Harris during World War II.

The store featured John Richmond's 1,300 ft (400 m) mural depicting the history of food from Prometheus to Marc Garneau.

This plan, however, was opposed by some members of the local community and led by the area alderman, a real estate broker, who felt the terminal would be "too disruptive to the existing fabric of development".

It was estimated that the terminal saw over 20,000 customers on opening day, with hour long lines and traffic jams surrounding the store.
