Third Parties

A third party is any person or entity that is not a political party, candidate or constituency association, and that engages in political advertising. Third parties include corporations, partnerships, unincorporated businesses and associations, and many other groups.

Therefore, if you plan to conduct political advertising during a general election or a by-election in Ontario, please be advised that there are registration and filing requirements as well as spending limits. These provisions are set out in sections 37.1 to 37.13 of the Election Finances Act. For further information refer to the CFO Handbook for Third Parties or contact the Compliance Division.

Third parties register with us by completing a Form TP-1 - Third Party Registration and Change Notice Form.
