A Canadian notary signs and seals your document. The notary can also prepare a separate certificate (sign it and attach it to your document).
When signing your document, the notary must:
have a valid certificate of appointment
handwrite their signature in ink
apply a stamp or seal showing their full name as it appears on their certificate of appointment and the Canadian province or territory in which they have been appointed
indicate the act they performed (e.g. certifying a true copy)
indicate the date on which they notarized the document
indicate the date on which their appointment as a notary expires (if applicable)
