In the 2025 Canadian federal election, 122 members of Parliament were elected to the House of Commons from the province of Ontario (35.6% of all members).
Background 2022 electoral redistribution The 2025 Canadian federal election was the first election to utilize the electoral districts established following the 2022 Canadian federal electoral redistribution. The House of Commons increased from 338 seats to 343 seats, with Ontario gaining one seat in an increase from 121 to 122. This ensures that the average population per constituency in Ontario is 116,590 (according to the 2021 Canadian census), which is 8,742 more people per electoral district than the national average. Due to the redistribution, this was the first Canadian federal election where the city of Toronto has less seats than its surrounding suburban municipalities within the Greater Toronto Area. + 2021 results transposed onto 2023 boundaries Party MPs 2021 actual result 2021 notional result Change 78 77 1 37 40 3 5 4 1 1 1 Total seats 121 122 1
