This is a list of electoral districts or ridings in Canada from 1871 to 1872, according to the British North America Act. No elections were held at this time, except to elect new members from Manitoba which joined confederation in 1870. New seats were added in 1872 as British Columbia had joined Confederation as a province the year before, with special byelections being called to fill the seats and temporary seatnames until the general election. Of these, only two seats (New Westminster District and Vancouver) were contested, the others being filled by acclamation.
Electoral districts are constituencies that elect members of Parliament in Canada's House of Commons every election.
