Plain-English guide to notary fees in Ontario — what a typical notarization costs, what affects pricing, and what to ask before booking.
Typical fee ranges
Individual notaries set their own fees. Typical 2026 ranges in Ontario: commissioning an affidavit $20–$50 per signature; standard notarization $25–$60 first signature with additional signatures often discounted; certified true copy $20–$40 per document; US-bound notarization with full certificate $50–$120; mobile or curbside $100–$250 for a typical GTA visit; virtual commissioning usually similar to in-office.
What affects the price
Complexity of the document. Number of signatures. Whether a certificate page is required. Whether authentication or legalisation follows (Global Affairs Canada and consulate fees are separate). Mobile travel. Urgency.
What to ask when you book
What is the all-in fee for my specific document? Are taxes included? Discount for additional signatures? If I need authentication or US Consulate registration, what’s the additional cost? Accepted payment methods?
Why fees vary
Notaries set fees based on overhead, location, experience, and specialization. Lawyers who are also notaries may charge more than paralegal commissioners because they bring broader legal expertise.
Frequently asked questions
Is there a regulated maximum fee?
Ontario does not regulate notary public fees.
Why is US-bound work more expensive?
It takes longer; the certificate is more involved.
Do I tip a notary?
No. Notarial fees are professional fees, not tipped services.
