Notary Public · Ontario
Notary public: what they do, and when you need one instead of a commissioner.
A notary public certifies true copies, witnesses signatures with a seal, issues notarial certificates and prepares documents for use outside Ontario. Those acts need the original in hand — so notarial acts are completed in person.
Illustrative sceneA notary public can
- Certifies true copies against the original
- Witnesses signatures and applies a notarial seal
- Issues notarial certificates (e.g. for apostille)
- Administers oaths and declarations (everything a commissioner does)
A notary public can't
- Certify a copy without seeing the original
- Apply a physical seal over video
- Guarantee acceptance by a foreign authority
- Give legal advice (unless also a lawyer)

Notarial acts that need the original examined or a seal applied are done in person. The oath-taking part of a notary's authority can be done by video where eligible.
Who holds the authority
In Ontario, lawyers may be appointed notaries public; non-lawyers can be appointed under the Notaries Act for the services and term of their appointment. In British Columbia, notaries are a regulated profession with a broader scope.
