Are electronic signatures legally binding in Ontario?

Yes, in most cases. Ontario's Electronic Commerce Act, 2000 recognizes electronic signatures as valid, provided there is clear intent to sign, consent to electronic dealings, and a reliable link between the signature and the document. This is general information, not legal advice.

Do I need a special type of signature for contracts in Ontario?

No specific technology is mandated for most commercial contracts. What matters is that the signature method reliably captures intent and that the signed record can be verified later, such as through a document hash and audit log.

Are there documents that can't be signed electronically in Ontario?

Yes. Certain documents, including wills, some powers of attorney, and specific government forms, have statutory requirements that may exclude electronic signatures. Check with a lawyer if you're unsure about a specific document type.

How does VG·Sign prove a signed document wasn't altered?

VG·Sign generates a SHA-256 hash of the final signed PDF and maintains an append-only audit log of each signing event. Together, these allow you to verify that the document matches what was originally signed.

Electronic Signature Ontario: Legality and How to Sign Online

If you run a business in Ontario, chances are you already send contracts, offer letters, or consent forms by email. The question is whether an electronic signature on those documents actually holds up. The short answer: yes, under the right conditions. Here's what the law says and how to sign documents online the right way.

Is an electronic signature legal in Ontario?

Ontario's Electronic Commerce Act, 2000 (ESA 2000) recognizes electronic signatures as legally valid for most business and consumer agreements. At the federal level, the Personal Information Protection and Electronic Documents Act (PIPEDA) and the Uniform Electronic Commerce Act (UECA) reinforce the same principle across Canada: an electronic signature can carry the same legal weight as a wet-ink one, provided it meets a few basic conditions.

This is general information, not legal advice. If you're dealing with a high-stakes contract, wills, powers of attorney, or a document with specific statutory signing requirements, talk to a lawyer before relying solely on an e-signature.

What makes an e-signature enforceable

Clear intent to sign: the signer must knowingly and deliberately execute the document.
Consent to do business electronically: most platforms capture this as part of the signing flow.
Association with the document: the signature method must be reliably linked to the specific record.
A way to verify the record hasn't changed after signing.

How electronic signatures actually work

A typical e-signature platform lets you upload a document, place signature and date fields, and send it to one or more recipients. The recipient opens a link, reviews the document, and applies their signature electronically. Once everyone has signed, the platform locks the final PDF.

To prove that final PDF hasn't been altered, VG·Sign generates a SHA-256 hash of the completed document and keeps an append-only audit log recording each step: when the document was sent, viewed, and signed, along with IP and timestamp data. If even one byte of the PDF changes later, the hash won't match, which is how integrity gets verified after the fact.

A practical signing workflow

Upload your contract, agreement, or form as a PDF.
Add signature, initial, and date fields for each party.
Send the document by email with a secure signing link.
Each signer reviews and applies their signature online.
The completed PDF and audit trail are stored and available for download.

Where your data is processed

VG·Sign's infrastructure runs on Supabase (hosted on AWS in the us-west-2 region) and Vercel. Data is processed in the United States, and VG·Sign applies contractual and technical safeguards intended to provide a level of protection consistent with Canadian privacy expectations. This is disclosed clearly so businesses can make an informed choice about where their signed documents are handled.

Choosing an e-signature tool in Ontario

Many Ontario businesses start with a big-name US platform and later look for something simpler and more transparent about pricing and data handling. If that's you, our comparison of options is a useful starting point.

Common mistakes to avoid

Sending a document without confirming the signer's identity through email verification or a secure link.
Using a static image of a signature pasted into a Word document with no audit trail.
Failing to keep a copy of the signed PDF and its verification record.
Assuming every document type can be signed electronically without checking specific legal exceptions.

An electronic signature is only as strong as the record and process behind it.

For most everyday business documents in Ontario, electronic signatures are not just legal, they're the practical default. The key is using a tool that keeps a clear, verifiable record of what was signed and when.
