We often are asked what is the difference between a Commissioner for Oaths and a Notary Public.
A Commissioner for Oaths, appointed in Alberta, is only allowed to administer oaths and take and receive affidavits, affirmations, and declarations for documents used in Alberta.
Generally speaking, only notaries, which include judges and lawyers, can witness or certify and attest deeds, contracts and commercial instruments, and issue a certificate under the Guarantees Acknowledgment Act.
This means that if you need a document witnessed, or certified as a true copy, or a document that needs to be sworn or used outside of Alberta, or if you sign a personal guarantee, only lawyers can exercise these functions.
A document may state that a "Commissioner for Oaths" may sign, but ultimately one has to look at the statutory authority in Alberta that outlines what Commissioners are allowed to do.
If you need an affidavit sworn or affirmed, or a statutory declaration declared, you may use a Commissioner for Oaths to take your otah/affirmation/declaration if the document is used in Alberta. If you require other legal services, you need a lawyer/notary.
