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.
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.
Elections Ontario’s Compliance Division is available to assist with any questions.
A third party must register with Elections Ontario after incurring expenses of $500 or more on political advertising in either the 12 months before the issue of a writ for a general election (the non-election period) or during an election period.
Third parties register with us by completing a Form TP-1 - Third Party Registration and Change Notice.
For further information refer to the CFO Handbook for Third Parties or contact us.
