Freemasonry is a fraternal organisation that arose from the loose organization of medieval masons (i.e. stone workers) working in the medieval building industry.^[1]

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.^[2] The Castle Island Virtual Lodge No. 190 is an example of an internet lodge whereby meetings are conducted online rather than in person.
