The 2021 Canadian Championship was the fourteenth edition of the Canadian Championship, contested from August 15 to November 21, 2021. The winners of the tournament, CF Montréal, were awarded the Voyageurs Cup and earned a berth in the 2022 CONCACAF Champions League.
The competition followed a similar format to the originally proposed 2020 edition with four rounds and regional pairings in the first two rounds. For the first time in the Canadian Championship, each tie was played as a single-leg fixture. CF Montréal, Forge FC, and Toronto FC entered the tournament in the quarter-finals due to their placements in the 2019 and 2020 editions of the competition. All other teams entered in the preliminary round of the tournament.
A.S. Blainville and Master's FA were originally supposed to participate in the 2020 edition of the competition, as they won the 2019 editions of the Première ligue de soccer du Québec and League1 Ontario, respectively. As the format of the 2020 edition was revised, their participation was postponed to the 2021 tournament.
Note
The bracket was announced on July 19, 2021.
The preliminary round matches were held between August 15 and 26, 2021.
