Is it permitted?
Ontario permits certain documents to be commissioned and witnessed by two-way audio-visual technology under the Commissioners for Taking Affidavits Act and Law Society guidance. Whether it applies to your document depends on the document and the receiving party.
What you need
A device with a working camera and microphone, a stable connection, valid government photo ID, and your document completed but unsigned. No printer or scanner is required.
What to expect
You join a live video session, your identity is verified, you swear or affirm on record, then sign on screen while the commissioner watches. A completed PDF with the commissioner’s signed jurat is issued afterward, along with a timestamped record of the session.
