Members

Note: The column "Party held electorally since" provides a notional measure of partisan support longevity for each electoral district, but with these caveats:
  • It discounts representation by a rival party if the rival party only represented a minority portion of the district.
  • It discounts interruption caused by floor-crossing, MPs leaving caucus to sit as independent or joining a breakaway caucus that existed for a short period, etc.
  • It treats the Conservative Party and its formal predecessor parties (Progressive Conservative, Reform and Canadian Alliance) as the same party, but treats Social Credit as a rival party because it never formally merged into the Conservative Party.
