The story
Founded by Steve Stavro in 1951.1
Knob Hill Farms began as a small east Toronto fruit stand in 1951, operated by Steve Stavro, his brother Chris and their father. Stavro said he took the name from a box of produce from California. At the time, Stavro had dropped out of high school to work in retail with his father. By 1954, Steve was running his own traditional grocery store at 425–427 Danforth Avenue. By the late 1950s, Stavro was operating nine grocery stores and outdoor markets in Toronto.
