Freemasonry is a fraternal organisation that arose from the loose organization of medieval masons (i.e. stone workers) working in the medieval building industry.
Freemasonry in Canada traces its origins to the United Grand Lodge of England, the Grand Lodge of Scotland and the Grand Lodge of Ireland, as a result of Canada's history as a dominion within the British Empire. Freemasonry in the United States, including Prince Hall Freemasonry, also influenced the formation of Freemasonry in Canada. Erasmus James Philipps became a Freemason while working on a commission to resolve boundaries in New England and, in 1739, became provincial grand master for Nova Scotia; Philipps founded the first Masonic lodge in Canada at Annapolis Royal, Nova Scotia.
There is a number of various supreme organisations (Grand Lodges, National Lodges, Grand Orients, and Federations) active in Canada representing a number of regularity / amity networks along with a number of independent lodges. All lodges recognized by GLCPOO are in amity with UGLE and the rest of "Regular" Masonry
