Quebec holds 78 seats in the 338-member House of Commons, Canada's lower parliamentary chamber.
Seat distribution is recalculated after each decennial census (most recently 2021) according to a constitutional formula that aims for representation by population, with certain guarantees for smaller provinces and Quebec specifically.
As Canada's second-most populous province, Quebec's delegation is the second largest after Ontario (121 seats). The province's distinct civil law system and French-language majority make its parliamentary caucus uniquely influential in federal legislation.
