If you’re a Canadian resident in the Greater Toronto Area who needs to sign documents for use in the United States, the process is usually simpler than people assume. For the vast majority of routine US matters — state-level real estate transactions, powers of attorney, corporate agreements, sworn declarations — an ordinary Ontario notary public’s seal is fully recognized and legally sufficient on its own. No consulate stamp, no apostille, no special procedure required.
This guide walks through what’s actually required, when extra authentication helps, and how the process has changed since Canada joined the Hague Apostille Convention on January 11, 2024.
Step 1: Confirm what your US recipient actually needs
Before doing anything else, ask the US lawyer, lender, title company, or government agency exactly what they require. In most cases the answer is simply “have it notarized.” That means a sworn signature in front of an Ontario notary public — nothing more.
Where added authentication may be requested:
- A US federal agency (for example the IRS or USCIS) that wants government-issued verification of the notary’s authority
- A US state or county recorder that explicitly requires an apostille on a foreign-executed document
- A title insurer with internal policies that ask for additional verification on cross-border closings
For everyday transactions — refinancing a Florida property, signing a Delaware corporate consent, executing a US power of attorney for a relative — a standard Ontario notarization is typically all that is needed.
Step 2: Find a qualified Ontario notary public
In most cases a standard Ontario notary public is fully recognized and legally sufficient. You do not need a specialized provider or a notary with US credentials.
Some Toronto notaries choose to proactively register their signatures and seals with the United States Consulate General in Toronto. Registration can make manual verification easier for strict federal files, but it is not a legal requirement — any properly appointed Ontario notary can successfully execute your US documents under the Notaries Act, R.S.O. 1990, c. N.6.
What to look for in any Ontario notary:
- Currently appointed under the Notaries Act (lawyers and licensed paralegals in good standing with the Law Society of Ontario are appointed on the same footing)
- Experience with US-style acknowledgements and jurats
- Willingness to use the wording your US recipient has supplied
Step 3: Prepare your documents and identification
Bring the document unsigned. A notary cannot acknowledge a signature that was already made out of their presence. You will also need government-issued photo identification — typically a current passport or driver’s licence. If a US form requires a witness in addition to the notary, arrange one in advance (some notaries can provide a witness on-site).
If the US form contains a state-specific acknowledgement block (for example California or New York wording), bring it as-is. The Ontario notary will use that exact wording rather than substituting Ontario-style language.
Step 4: Sign in person before the notary
The notary will verify your identity, confirm that you understand the document, and watch you sign. They will then complete the acknowledgement or jurat, affix their seal, and sign as notary public. For most US documents that completes the process — the document is ready to send.
This step must be done in person. Notarial acts in Ontario — witnessing signatures, certifying true copies, applying the notary’s seal — require the notary and the signer to be physically together. Ontario law permits remote commissioning of oaths and declarations by two-way audiovisual under O. Reg. 431/20, but that is a different act from notarization. The Notaries Act still requires in-person presence for notarial work, and the Law Society of Ontario has formally confirmed that online or video-based notarization is not legally valid in Ontario.
Step 5: Obtain an apostille (only if explicitly required)
Most everyday US transactions do not require any extra steps beyond the notary’s seal. However, if a US recipient or federal agency explicitly demands official government authentication of the notary’s signature, the process is now much simpler than it used to be.
Canada officially joined the Hague Apostille Convention on January 11, 2024. The old multi-step chain — authentication by Global Affairs Canada followed by legalisation at the US Consulate — is obsolete for this purpose. Instead, a single apostille certificate replaces both stamps.
In Ontario, apostilles for documents notarized by an Ontario notary are issued by Official Documents Services (ODS), part of Ontario’s Ministry of Public and Business Service Delivery and Procurement — the provincial competent authority designated under the Convention. ODS issues the apostille directly on or attached to your notarized document; the United States, as a Convention party, accepts it on its own with no further consular stamp required.
To recap: in 2024 and beyond, the maximum sequence for a US-bound document is (1) notarize in Ontario, (2) if explicitly required, get an apostille from ODS. There is no longer a Global Affairs Canada step and no consular legalisation step for any country that is a Convention party — and the United States is.
Step 6: Send to the US recipient
Originals are normally required. Courier the signed (and, if applicable, apostilled) document directly to your US lawyer, title company, or recipient. Keep a scanned copy for your records.
Frequently asked questions
Can any Ontario notary notarize a US document?
Yes. Under standard cross-border legal recognition, an ordinary Ontario notary’s seal is widely accepted across the United States. Unless your specific recipient or a federal agency explicitly requests a provincial apostille for official tracking, a standard in-person notarization is all you need for real estate, estate, or corporate matters in almost every state.
Do I need a notary who is registered with the US Consulate?
No. Registration is a convenience, not a requirement. Any properly appointed Ontario notary can notarize a document destined for the United States. Consulate registration can speed up verification in a small number of federal files, but it has no effect on the legal validity of the notarial act.
Is an apostille always needed for US documents?
No. An apostille is only needed when the US recipient or agency explicitly asks for one. Most state-level transactions — including real estate closings, powers of attorney, and corporate filings — do not require an apostille. Ask the recipient before going to ODS.
What changed in 2024?
Canada became a party to the Hague Apostille Convention on January 11, 2024. The old chain of Global Affairs Canada authentication plus US consular legalisation has been replaced by a single apostille certificate, issued in Ontario by Official Documents Services. The apostille is accepted in the United States and in all other Convention countries with no further consular stamp.
Can I do this remotely?
No. The notarial portion of a US document — witnessing your signature and applying the notary’s seal — requires the notary and the signer to be physically together. Ontario law permits remote commissioning of oaths and declarations by two-way audiovisual under O. Reg. 431/20, but that is a different act from notarization. The Notaries Act still requires in-person presence for notarial work. US recipients overwhelmingly require wet-ink, in-person notarization in any event.
