Is An Electronic Signature Legally Binding In Canada?

Canada recognises electronic signatures. A customer tapping a signature onto a quote on your phone is, for ordinary commercial work, entering the same agreement they would by signing a printed copy. Contractors have been closing work this way for years and courts have not treated it as exotic.

Two layers of law sit behind that. Federally, the Personal Information Protection and Electronic Documents Act sets out how electronic documents and "secure electronic signatures" can stand in for paper where a federal statute or regulation requires a signature. That federal framework is narrower than people assume — it governs federal requirements, not every private contract in the country.

The layer that actually covers your quote is provincial. Most provinces and territories have their own electronic-commerce or electronic-transactions legislation, largely built on a shared model, which says a signature is not invalid merely because it is electronic. Ontario's Electronic Commerce Act, 2000 is one example. Quebec's framework is built differently from the common-law provinces', so if you work there, get advice specific to it rather than assuming the same rules apply.

The provincial Acts carve out a short list of documents that still want paper and traditional formalities. The list varies by province, but it consistently covers things well outside a contractor's day: wills and codicils, trusts created by wills, certain powers of attorney, negotiable instruments, and some documents transferring an interest in land.

A quote, a change order, a work agreement and a deposit authorisation are not on anybody's exclusion list. If your work involves transferring land or anything touching estates, that is the point to stop and ask a lawyer — not because e-signature is risky, but because those documents have their own formalities.

Validity is rarely the fight. When a signed document is challenged, the argument is almost never "electronic signatures aren't legal" — it is "that isn't what I agreed to" or "I never signed that." What wins that argument is evidence, and evidence is a product decision, not a legal one.

A signature worth relying on can answer five questions without you having to remember anything:

"Audit trail" sounds like compliance jargon; in practice it is a short, boring log that turns a disputed memory into a record. At minimum it should capture when the quote was sent and to which address, when it was opened, when it was signed, the IP address it was signed from, and a locked copy of the document exactly as it appeared at signature.

That last part is the one people skip. If your system lets you edit a quote after it is signed without preserving what was signed, the audit trail proves very little. QuotingAI records the signature event and keeps the signed version intact, so the copy you can produce later is the copy the client agreed to.

None of this is exotic or expensive. It is the difference between "I'm sure they approved the extra" and a dated record showing they did.

Send the quote to one named person at their own email address rather than a shared inbox. Put the scope and the price in the document being signed, not in the covering message. Make sure the client receives a copy automatically once it is signed. Keep change orders on the same footing as the original quote, signed before the work happens.

Do those four things and the question of whether an electronic signature is binding stops being interesting, because you will have a clear record of who agreed to what and when.
