King Street is a major east-west commercial thoroughfare in
Toronto,
Ontario,
Canada. It was one of the first streets laid out in the 1793 plan of the
Town of York, which became Toronto in 1834. After the construction of the Market Square in 1803 at King and Jarvis streets, to house the first
St. Lawrence Market farmer's market, the street became the primary commercial street of York and early Toronto. This original core was destroyed in the
1849 Great Fire of Toronto, but subsequently rebuilt. The original street extended from George to Berkeley Street and was extended by 1901 to its present terminuses (both with Queen Street) at Roncesvalles Avenue in the west and the Don River in the east.
