Proof of Loss Affidavit Notarization – What Ontario Policyholders Need to Know
In Ontario, insurance companies often require a notarized Proof of Loss affidavit when processing certain claims. This affidavit is a sworn declaration confirming the details of your loss — including the cause, extent of damage, and estimated value of the affected property.
To be valid, the document must be
signed and commissioned by a licensed Notary Public, paralegal, or commissioner of oaths in Ontario.

Why Notarization Is Required
Legal Verification
Notarization confirms that the affidavit is a genuine legal statement made under oath or affirmation. It helps establish the truthfulness and intent behind your declaration.
Insurance Company Requirements
Most insurance providers require the Proof of Loss affidavit to be notarized as a condition of claim acceptance — especially for larger, disputed, or complex claims.
Accuracy and Accountability
Notarization reinforces that the claimant is aware of the legal consequences of submitting false or misleading information. It ensures the document can be used as formal evidence in insurance reviews or disputes.
Fill out your insurance company’s Proof of Loss form, including:
- A description of the incident (fire, flood, theft, etc.)
- Estimated value of the damaged or lost items
- Policyholder information and relevant claim numbers
You’ll need to show valid identification and sign the affidavit in front of the notary. They will administer the oath or affirmation, verify your identity, and officially commission the document.
To commission the affidavit, meet with an authorized Notary Public or commissioner of oaths. This can be done:
- In person at a notary office
- On-site at your home or office through a mobile notary
- Via secure video call using
online commissioning (if you're located in Ontario)
Why Notarization Is Needed
- Legal Verification: Affidavits provide a sworn, legally enforceable confirmation of corporate data
- Government Compliance: Most provincial agencies will not accept corporate declarations without proper commissioning
- Internal Accountability: Ensures that the company officer making the declaration understands its legal impact
