Middlesex was an electoral district of the Legislative Assembly of the Parliament of the Province of Canada, in Canada West (now Ontario). It was created in 1841, upon the establishment of the Province of Canada by the union of Upper Canada and Lower Canada. Middlesex was represented by one member in the Legislative Assembly. It was abolished in 1867, upon the creation of Canada and the province of Ontario, and succeeded by three different ridings for both the federal Parliament and the Ontario Legislative Assembly.
