London Conference of 1866

The London Conference was held in London, in the United Kingdom, in 1866. It was the third and final in a series of conferences that led to Canadian Confederation in 1867. Sixteen delegates from the Province of Canada, Nova Scotia, and New Brunswick gathered to set out the final outline of the proposed Canadian Confederation, resulting in the British North America Act, 1867 (now the Constitution Act, 1867).

Upon the conclusion of the discussions by the delegates, the British government directed that a bill be drafted to implement the resolutions of the Conference. Introduced in 1867, the British North America Act, 1867 was passed by both Houses of Parliament and then received royal assent from Queen Victoria on March 29, 1867. It was proclaimed in force on July 1, 1867, creating the Dominion of Canada.
