Are persons who are empowered under provincial or state legislation to administer and witness the swearing of oaths or solemn affirmations in the taking of an affidavit for any potential legal matters.
Commissioners of oaths are also empowered to witness any declaration as required under a statute. The person swearing an oath, making an affirmation or making a declaration is called a deponent or declarant. A commissioner of oaths only certifies that the required oath or affirmation or declaration has been properly administered.
Commissioners of oaths do not certify the truth of the statements contained in a document; which remains the responsibility of declarants or deponents themselves. In most provinces and states, a commissioner of oath must administer the oath or declaration in the manner prescribed by law.
