How this is calculated

  • Lobbyists are ranked by the number of different organizations they were registered to lobby for at any point in the current and previous calendar years (2025 and 2026), in the federal lobbyist registry and those of Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island and Saskatchewan. The window moves forward each January. The Quebec and Newfoundland and Labrador registries are not included. Ties go to the lobbyist registered in more jurisdictions.
  • Lobbying firms are ranked the same way, by the number of different organizations they were registered to lobby for in the same period and registries. Ties go to the firm registered in more jurisdictions.
  • A client counts only when its registration names three lobbyists or fewer. Alberta's registry lists a firm's whole team on every client, which would otherwise credit each member of the team with all of the firm's clients.
  • The three-lobbyist limit does not apply to firms: every registration counts toward its firm, however many lobbyists it names. In-house lobbyists, who work directly for the organization they lobby for, are not attached to any firm and so count toward none.
  • A lobbyist or firm registered in several jurisdictions is counted once, and so is an organization that appears in the registries under several names.
  • The former public office badge is context only and does not affect the ranking: only the federal and BC registries record past offices.
  • For Alberta we currently hold only active registrations, so Alberta registrations that ended after January 1, 2025 are not yet counted.
