General information

There are rules for third party advertising in Ontario’s municipal council and school board elections.

A third party advertisement is an ad that supports, promotes or opposes a candidate or a “yes” or “no” answer to a question on the ballot.

The meaning of “third party” in this context means a person or entity who is not a candidate. Eligible individuals, corporations and trade unions can register to be third party advertisers. Third party advertising is separate from any candidate’s campaign and must be done independently from a candidate.

Third party advertisers who want to spend money on advertisements during the election must register with the municipal clerk and must file a financial statement.

For more information about third party advertising rules, including eligibility, spending limits and enforcement, see the Third Party Advertisers’ Guide.
