Can I sue the Ontario provincial government or a municipality in Ontario?

TSL Written by the Treadstone Law team· Updated June 2026

Yes, you can sue the Ontario provincial government or a municipality, but special rules apply. The province and its Crown agencies can be sued in Ontario under the Proceedings Against the Crown Act. You can commence a civil action against the Crown for the same types of wrongs — negligence, breach of contract, property damage — that you could pursue against a private party, but the process has some differences.

For personal injury claims against a municipality, you must typically provide written notice to the municipality within a short period after the incident, as required by the Municipal Act, 2001 or the City of Toronto Act, 2006. Failure to provide notice on time can be a complete bar to your claim, even if it is otherwise valid. This notice requirement is separate from the limitation period, and both deadlines must be respected.

Human rights complaints against the government follow a different track under the Human Rights Code and are handled by the Human Rights Tribunal of Ontario rather than the courts in the first instance.

Suing government entities involves procedural nuances that differ from private litigation. Some claims — particularly those challenging government decisions or policies — may require judicial review rather than a civil action. A lawyer can assess the right forum and the applicable procedural rules for your specific situation.

Key takeaways

  • You can sue the Ontario provincial government under the Proceedings Against the Crown Act.
  • Municipal claims often require written notice within a short period after the incident.
  • Missing the municipal notice deadline can bar your claim entirely.
  • Human rights complaints follow a separate track through the Human Rights Tribunal of Ontario.
