Old Toronto is the part of Toronto, Ontario, Canada, that corresponds to the boundaries of the City of Toronto prior to 1998. It was incorporated as a city in 1834, after being known as the town of York, and being part of York County. Toronto periodically grew in size by annexing adjacent land and municipalities.
In 1954, the City of Toronto and the surrounding suburban towns and townships of York County were joined in a federation known as the Municipality of Metropolitan Toronto (Metro). Later, the lower-tier city annexed two towns until it reached its final boundaries in 1967. In 1998, the municipalities of Metro Toronto were amalgamated into the present-day single-tier City of Toronto, which continues legally from the predecessor City of Toronto, although the by-laws of each municipality remained in force.
