  The 2021 Canadian federal election, held on September 20, 2021, saw only minor changes from the preceding 2019 election. The incumbent Liberal Party, led by Prime Minister Justin Trudeau, did not win the popular vote and failed to win enough seats to gain a parliamentary majority, winning only a plurality of seats and retaining its status as a minority government. The Conservative Party won the popular vote and continued as the Official Opposition. In March 2022, the Liberals struck a deal with the fourth-place New Democratic Party (NDP), where the latter would provide confidence and supply for the duration of the Parliament in exchange for certain policy concessions. The agreement lasted until September 2024, when the NDP terminated the deal.
  
  One week after the 2021 election, on September 27, Annamie Paul resigned as the Green Party leader, citing lack of party support. The subsequent leadership election was won by former leader Elizabeth May, who ran on a "joint ticket" with Jonathan Pedneault, proposing a co-leadership model; Pedneault was officially named the deputy leader, pending a change to the party's constitution to allow co-leadership. May and Pedneault formally became co-leaders on February 4, 2025.
  
  On February 2, 2022, Conservative leader Erin O'Toole was removed as leader by a caucus vote. Following a leadership election, Pierre Poilievre was elected the new leader of the Conservative Party.
  
  Because of the decennial redrawing of riding boundaries, many MPs were running in districts that had changed.
