Be a commissioner for oaths

Becoming a Commissioner for Oaths

You may apply to be appointed as a Commissioner for Oaths if you meet the following conditions:

  • you are 18 or over
  • you are a permanent resident or Canadian citizen
  • you must administer an oath to a person for a document for use in Québec.

You cannot apply to certify documents, authenticate persons, perform community service, or produce certified copies of documents. Applications submitted for such purposes will be rejected.

The mandate of a commissioner for oaths lasts 3 years. It is valid for any oath relating to proceedings or documents intended solely for use in Québec, regardless of the scope of the mandate.

The scope varies depending on where you live.

If you reside in Québec, you may administer oaths:

  • in Québec only, or
  • both in and outside Québec.

If you reside outside Québec, you may administer oaths:

  • both where you reside and elsewhere (anywhere in Canada or any other country), or
  • where you reside only (in your country or your Canadian province or territory).
