Elections Canada says four more seats will be added to the House of Commons over the coming years.
The number of seats is recalculated after each 10-year census to account for population changes.
Alberta will get three of the new seats, bringing its total number of seats to 37.
Ontario and British Columbia will each get one new seat. They will have 122 and 43 seats, respectively.
Quebec, meanwhile, will lose one seat, bringing its total down to 77,
Nova Scotia will continue to have 11 seats, New Brunswick will maintain its 10 seats, Newfoundland and Labrador will keep its seven seats, and Prince Edward Island will continue to have four seats.
Manitoba and Saskatchewan will keep each of their 14 seats, while there will continue to be one seat each in Yukon, the Northwest Territories, and Nunavut.
The new seat allocation serves as a basis for redrawing the federal electoral district boundaries within each province.
The process, which will be led by independent and non-partisan commissions established in each province, should begin in February.
Elections Canada says the new electoral map is expected to be done in late 2023, but the changes will not take effect until at least 2024.
