Results breakdown of the 2021 Canadian federal election

"[1] The remarkable similarity of the seat results and those in 2019 may have reinforced voters' sentiments that the early election was unnecessary, and its meagre outcome has left its mark on the electorate.

Compared to 2019, Tory holds in Western Canada and Liberal ones in the GTA both declined, although one Conservative observer noted, "I am far more encouraged by the narrowing of margins in the suburbs, than I am discouraged or concerned by an Alberta MP only winning by 30,000 votes".

Internal dissension and poor morale contributed to the decline, and Elizabeth May called for an inquiry to determine the underlying reasons for it.

[5] In late November, the Greens released a report indicating that they were facing imminent insolvency, and were considering closing the Ottawa office.

The following tables show the margins over the various 2nd-place contenders, for which one-half of the value represents the swing needed to overturn the result.
