Background and detail

Background. The formation of the United Province of Canada reflected recommendations from John Lambton, 1st Earl of Durham, following the Rebellions of 1837–1838. While Durham called for responsible government, only the union was implemented in 1841. The Act abolished the separate parliaments of Upper and Lower Canada, replacing them with a single legislature consisting of a Legislative Council and a Legislative Assembly.

Implementation. Charles Poulett Thomson, 1st Baron Sydenham, succeeded Lord Durham as Governor General in 1839. He was responsible for implementing the Union Act, uniting the two colonies and moving the seat of government to Kingston. The Act was approved by Parliament in July 1840 and proclaimed on 10 February 1841, officially marking the beginning of the new province.

Capital. Kingston served as the first capital of the United Province of Canada from 1841 to 1844. The seat of government and bureaucracy moved to Montreal in 1844. The legacy row's location 'Kingston, Ontario' is anachronistic, as Ontario did not exist as a province until 1867; the correct historical referent is Kingston within the United Province of Canada.
