In contrast with the political party systems of many nations, Canadian political parties at the federal level are often only loosely connected with parties at the provincial level, despite having similar names and policy positions. One exception is the New Democratic Party, which is organizationally integrated with most of its provincial counterparts including a shared membership. Current parties House of Commons Represented parties Registered parties The following political parties are registered with Elections Canada and eligible to run candidates in future federal elections, but are not currently represented in the House of Commons. Eligible parties Eligible parties have applied to Elections Canada and met all of the legal requirements to be registered, other than running a candidate in a general election or by-election. Such parties are eligible to run candidates in federal elections but will not be considered "registered" by Elections Canada until they have registered a candidate in an election or by-election. As of August 2022, the following are eligible parties: Non-party parliamentary groups At various points both the House of Commons and Senate have included non-party parliamentary groups, also called caucuses. These groups are unaffiliated with registered political parties, are not registered with Elections Canada, and do not run candidates in Canadian federal elections. Essentially, these parliamentary groups are equivalent to political parties in the legislative context, but do not exist in an electoral capacity. Parliamentary groups in the House of Commons of Canada are typically made up of MPs that separate from a party over leadership conflicts. Notable past parliamentary groups in the House of Commons include the Ginger Group (1924–1932; split from Progressive Party), Democratic Representative Caucus (2001–2002; split from Canadian Alliance), and Québec debout (2018; split from Bloc Québécois). Senate The Senate of Canada currently has three non-party parliamentary groups: the Independent Senators Group (ISG), the Canadian Senators Group (CSG), and the Progressive Senate Group (PSG). These three groups do not share a formal ideology, platform, or membership in any one political party; the caucuses primarily serve to provide organizational support and better leverage parliamentary resources. Conservative senators remain formally affiliated with the Conservative Party of Canada. Historical parties House of Commons Registered parties These are political parties which either ceased to exist before Elections Canada was formed, or were once registered with Elections Canada but have become de-registered or ceased to exist due to dissolution.
