What is document commissioning, and can it be done online in St. Catharines?

Commissioning is when a Commissioner for Taking Affidavits administers an oath or affirmation and witnesses your signature — the step most Canadian government and court documents require. For St. Catharines residents, many documents can be commissioned online over a secure video appointment under Ontario law (O. Reg. 431/20), including affidavits and statutory declarations. The notary verifies your identity, witnesses your signature, and applies the seal during the call.

Can I notarize documents online in St. Catharines?

Yes. Residents of St. Catharines can have many documents commissioned by an Ontario Notary Public over a secure video appointment under Ontario law (O. Reg. 431/20). This includes affidavits, statutory declarations, and certified copies of documents that were issued electronically. The notary verifies your identity, witnesses your signature, and applies the notarial seal during the call.

Do I need to live in St. Catharines to use this service?

No. For Ontario matters, the document must relate to an Ontario matter rather than your physical location. For federal documents — such as immigration paperwork — clients can join the video appointment from St. Catharines or anywhere else in Canada. If you are unsure whether your document can be completed online, contact us before booking.

How much does an online notary cost in St. Catharines?

Our flat rate is $19.90 per notarial seal plus HST, the same for every service. Online appointments add HST and a small card-processing fee, shown in full before you pay. There are no tiers or surprises.

Which documents cannot be completed online?

Some documents still require an in-person, wet-ink signature — for example certified true copies of paper originals, powers of attorney, real estate documents, and documents headed for Apostille or authentication abroad. For those, please call us at (613) 434-5555 to arrange an appointment.

What do I need for my online appointment?

You will need valid government-issued photo identification, the unsigned document, a device with a camera and microphone, and a stable internet connection. The notary will guide you through identity verification and signing during the call.
