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.

A 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)

Online?

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.
