Mimico is the oldest of the former Lakeshore Municipalities. The Town of Mimico was established by a plan of sub-division in 1856, but was not sub-divided from the former Township of Etobicoke until 1911. The land area of Mimico originated mainly from three family farms, namely: Stock Estate (North of Portland), Hendry Estate (between Royal York and Queens Ave), Van Every Estate (between Royal York Rd and Dwight Ave). Mimico was an independent municipality until 1967, when it was amalgamated into the new Borough of Etobicoke (later, City of, in 1984), which was itself amalgamated in 1998 into the current city of Toronto.
