Political Footprint
Donations · lobbying · contracts

5 insiders linked to TA are also individual political donors — $20K across 45 donations (2007–2023).

Conservative Party of Canada · $18K Liberal Party of Canada · $2K New Democratic Party · $260

Form55 also tracks TA's federal footprint: 11 lobbying registrations naming 14 departments.

Sources: Elections Canada (individual donations only — corporate political donations banned federally since 2007), the federal Registry of Lobbyists, and federal contract disclosures. Insiders matched to donors by name. Shown for transparency from disclosed public records — this is not a Confluence Score input, implies no causal link between donations, lobbying, or contracts, and is not a claim of wrongdoing.
