To apply for a Canadian passport, you normally need to provide the details of a guarantor — someone who has known you for at least two years and who attests to your identity. When no one meeting these criteria is available, Immigration, Refugees and Citizenship Canada (IRCC) instead accepts a sworn statement made in lieu of a guarantor.
This declaration must be signed before a notary public, a justice of the peace, or a commissioner for oaths if you are in Canada (or before a Canadian or British diplomatic representative, or a qualified local official, if you are outside Canada). According to IRCC, this person does not need to know you personally.
The oath, in brief
This document contains a declaration under oath or a solemn declaration: it must be signed before a person legally authorized to receive it — a Commissioner for Oaths, notary, lawyer, or justice of the peace. Once sworn, the declaration has the same weight as a statement made before a court.
In Québec, a Commissioner for Oaths can administer this oath remotely, by videoconference, when the required conditions are met (seeing and hearing each other, viewing the document, keeping it confidential).

Have this document sworn online
This declaration can be sworn online by videoconference before a Commissioner for Oaths, who does not need to know you: show valid photo ID and receive the signed document to attach to your passport application.
Before booking, confirm with the receiving organization that an oath administered by a Québec commissioner meets the requirement, especially if your file is handled outside Québec.
