= List of Canadian MPs by seniority (2021–present) = This is the list of Canadian MPs by seniority, 2021–present. The Members of Parliament (MPs), who were elected in the 2021 Canadian federal election and during the 44th Canadian Parliament, are ranked by the beginning of their terms in office in the House of Commons.

Criteria
The seniority criteria used in this article are derived from how the Father of the House is selected. They are not laid down in Standing Orders but arise from the customary practice of the House of Commons. The modern custom is that the Father of the House is the MP who has the longest continuous service. If two or more members were first elected in the same General Election (or at by-elections held on the same day), then priority is given to the one who was sworn in first. The order of swearing in is recorded in the House of Commons Journal, the official record of proceedings.

When a member has had broken service, that does not affect his or her seniority (for the purpose of qualifying as the Father of the House) which is based on the latest period of continuous service.

The Sinn Féin members, who abstain from taking their seats at Westminster, have never been sworn in. They are ranked (in this list) after all other members who have taken their seats. Between themselves, they are ranked by the first date of the election, for the current period of continuous service. If they are equal on that criterion, then they are ranked in alphabetical order by surname.

The seniority criteria used in this article are derived from how the Dean of the House (the member with the longest unbroken record of service) is selected. The Dean's primary responsibility is to preside over the election of the Speaker of the House of Commons, and to serve as Interim Speaker in the event of the resignation or death of the current speaker.

List
This article assigns a numerical rank to each of the 338 members elected in the 2021 federal election. Other members, who were not the first person declared elected to a seat but who joined the House during the Parliament, are not assigned a number. Members named in italics are no longer sitting.
