From 4 December 1866 to March 1867, politicians from the Province of Canada, Nova Scotia and New Brunswick met with delegates of the British government in London. This was the last of three conferences — after the Charlottetown Conference and Quebec Conference in 1864 — that were held to determine the constitutional details of Confederation. The Quebec Resolutions — 72 points that had been agreed upon in Quebec City — were reviewed and amended. They formed the basis of the British North America Act. It was passed by the British Parliament and received Queen Victoria’s Royal Assent on 29 March 1867.
