Hamilton electoral district was based largely on the municipal boundaries of the town of Hamilton, located at the western end of Lake Ontario in the central area of Canada West (now the province of Ontario).

[1] The Union Act provided that the town of Hamilton would constitute one electoral district in the Legislative Assembly of the new Parliament,[2] but gave the Governor General of the Province of Canada the power to draw the boundaries for the electoral district.

[3] The first Governor General, Lord Sydenham, issued a proclamation shortly after the formation of the Province of Canada in early 1841, establishing the boundaries for the electoral district: Hamilton was represented by one member in the Legislative Assembly.

[7] It was succeeded by electoral districts of the same name in the House of Commons of Canada[8] and the Legislative Assembly of Ontario.
