Usually if you are signing documents for use in another province or territory in Canada, the document should be sworn or affirmed before a Notary Public. If you are signing documents for use outside of Canada, the document should be sworn or affirmed before a Notary Public. The place where the document is going may also require a certificate of authentication. This certificate confirms the Notary Public's status, signature and seal. To get a certificate, contact the Deputy Provincial Secretary's Office. Getting a certificate can take time, depending on if you submit your request in person or by mail, so make sure you don't leave it until the last minute! Last Reviewed: December 2019
