Do I have to notify the government when my corporation's directors change?

Yes. Under the Corporations Information Act (Ontario), a corporation must notify the province when there is a change of directors. The notice of change must be filed within fifteen days of the change occurring. This applies to any addition, removal, or change in the information of a director, such as a change of address.

The notice of change is filed electronically through ServiceOntario or through a registered service provider. The filing fee is modest. You will need the director's full legal name, date of birth, address for service, and whether they are a resident Canadian (a requirement for some corporations).

Keeping director information current matters for practical reasons beyond legal compliance. If a third party needs to verify who controls the corporation — for a bank loan, a lease, or a business acquisition — they will check the public register. Outdated information can slow transactions down and raise red flags. Build director changes into your standard internal process so no deadline is missed.
