Commission of Oaths (Commissioner of Oaths)

Commission of Oaths/Commissioner of Oaths in North York, Toronto, Scarborough, Etobicoke, Brampton, Mississaugua, Vaughan, Canada


Persons who are authorized under regional or provincial legislation to administer and witness the swearing of oaths or solemn affirmations in order to take an affidavit for any potential legal matter are called “commissioners of oaths”. The person who makes an oath as an affirmation or declaration is called a “deponent” or “declarant”.

Commissioners of oaths in Canada are also certified to witness any declaration as required under a given law. A commissioner of oaths officially states that the required oath or affirmation or declaration has been properly administered. A commissioner does not verify the validity of the statements contained in a document. This is the responsibility of the deponents.

In nearly all Canadian provinces, a commissioner of oaths must administer the declaration by law. This requires that the deponent be physically present before the commissioner of oaths.

Before signing the document, the commissioner of oaths must be satisfied about the authenticity of the deponent’s identity and signature by comparing it to that in existence on a piece of identification, such as a driver’s license or a provincial health insurance card or passport.

Different Types of Oaths:

If an oath is witnessed by a commissioner of oaths then it is necessary for the deponent to confirm the following question: “Do you guarantee that the contents of this affidavit as subscribed by you are true?”

If such a type of oath is not required, then the deponent can confirm by responding ‘yes’ to: “Do you solemnly confirm and declare that the contents of this affidavit as subscribed by you are true?”.

In consistence with the requirement of a solemn declaration, the deponent must declare in the positive to: “Do you make this solemn declaration conscientiously, considering it to be true and knowing that it is of the same force and effect as if made under oath?”.

In all instances, it is required that the deponent be physically present before the commissioner of oaths.
