Lobbying is legal and registered. A meeting may be about anything; the subjects are the ones the registrant reported. Counts are communication reports in the federal Registry of Lobbyists that name a Member of Parliament or Parliamentary Secretary, one per report, since October 2025. Registrants have until the 15th of the next month to file, so recent weeks are undercounted.

Names are as the registrants filed them; MPs link to their pages when the name matches a sitting MP. Source: Registry of Lobbyists, Office of the Commissioner of Lobbying of Canada (lobbycanada.gc.ca). How this is counted: most active lobbyists.
