Commissioner for Oaths

How to obtain ...

Each person wishing to make a Solemn declaration on a document must come to City Hall in person with the completed but not signed form. A commissioner of Oaths will receive them and their oath. The person must present a piece of identification with photo.

There will be a charge for each photocopy that needs to be signed, plus taxes. Please refer to Tariff by-law for details.

Commissioner for oaths have the official title of “Commissioner for Oaths for Québec”.

Powers and restrictions

For a proceeding or document intended for use in Québec, a commissioner for oaths may:

  • administer an oath in Québec;
  • charge a maximum fee of $5 per oath.

Commissioners for oaths may not

  • receive, under oath, an affidavit made by a close relative (father, mother, brother, sister, spouse or child);
  • as part of their duties, attest that a copy of a document is identical to the original.

The person presenting the copy can make an oath before a Commissioner that it is identical to the original, but this does not make the copy an authentic document. Only the person having custody of an authentic document (such as a notary, in the case of a notarized will, or the registrar of civil status, in the case of an act of birth) can attest that a copy of such a document is also authentic.


Commissioners for oaths are not required to verify the accuracy of a statement sworn under oath; the person making the oath is responsible for the content of the resulting document.

However, commissioners for oaths may refuse to administer an oath if they note that:

  • the document is not in the required form, is visibly incorrect or contains gratuitous or offensive statements;
  • the person making the oath does not appear to be in full possession of his or her faculties or does not appear able to express his or her wishes.

Commissioners of oaths must require the person making the oath to sign the document in their presence, since the commissioner must be able to attest to both the oath and the person’s signature.
