The British North America Act, 1840 (3 & 4 Victoria, c.35), commonly known as the Act of Union 1840, was enacted in July 1840 and proclaimed February 10, 1841. It abolished the legislatures of Lower Canada and Upper Canada and established a new political entity, the Province of Canada to replace them. This act affected the political union of the Province of Canada, and was similar in nature and in goals to the other Acts of Union enacted by the British Parliament.
