[11] The Official Opposition Conservative Party argued that the pension eligibility was the real motivation for the change, an accusation which the government denied.

[12] Of the 80 MPs who would have become eligible for a pension if the election date was moved later, 32 were Conservatives, 22 were Liberals, 19 were Bloc Québécois, 6 were New Democrats, and 1 was an independent.

[13] The date change was unlikely to proceed with all opposition parties against the change; NDP MP Lisa Barron confirmed she would propose a committee amendment to leave the fixed election date as October 20, 2025, and minister of democratic institutions Dominic LeBlanc stated he would "happily respect the will of this committee" if it had amended the bill.

[15] The table below lists parties represented in the House of Commons after the 2021 federal election and their current standings.

Kevin Vuong, despite being elected as a Liberal, was disavowed by the party too late to alter his affiliation on the ballot and has since sat as an independent.

As well, the party in power does not need to obtain a majority of the seats in the House of Commons – and under the current multi-party system, quite often does not achieve that.

[citation needed] The Constitution Act of 1867 requires that federal electoral districts undergo a redistribution following each decennial Canadian census.

[18] On October 15, 2021, the chief electoral officer announced that, based on the formula in the Constitution Act, 1867, then in force, the allocation would result in an increase to 342 seats.

Consequently, media outlets tend to report seat gains and losses as compared to notional results.

These are the results if all votes cast in 2021 were unchanged but regrouped by new electoral district boundaries, as published by Elections Canada.
