Are electronic signatures legal in Canada?

The short answer

Yes. In Canada, an electronic signature is legally valid for the large majority of business documents: employment offers, sales contracts, leases, purchase orders, engagement letters, consent forms, NDAs and most internal approvals. A document is not invalid just because it was signed on a screen instead of on paper.

The longer answer is that Canada does not have one e-signature law. It has a federal law that covers federal matters and a set of provincial and territorial laws that cover almost everything else. They were written from the same model, so they say similar things, but the exceptions differ from province to province. This article walks through how they fit together. It is general information, not legal advice. If a document is unusual or high stakes, ask a lawyer in the province where it applies.

Two levels of law

At the federal level, Part 2 of the Personal Information Protection and Electronic Documents Act (PIPEDA) deals with electronic documents and signatures. It applies where a federal law requires a signature, a document in writing or an original. Part 2 also introduced the idea of a secure electronic signature, defined in the Secure Electronic Signature Regulations, for the narrow set of federal cases that ask for one. Most private contracts never touch these rules.

Contracts between businesses, and between businesses and people, are mostly a provincial matter. Every province and territory has an electronic commerce or electronic transactions statute. Most are based on the Uniform Electronic Commerce Act that the Uniform Law Conference of Canada adopted in 1999. Examples include Ontario's Electronic Commerce Act, 2000, British Columbia's Electronic Transactions Act, Alberta's Electronic Transactions Act, Saskatchewan's The Electronic Information and Documents Act, 2000, Manitoba's The Electronic Commerce and Information Act and Nova Scotia's Electronic Commerce Act.

Quebec took its own route with the Act to establish a legal framework for information technology. It works with the Civil Code of Quebec and focuses on the integrity of the document and the link between the signer and what they signed. The practical effect for most businesses is the same: an electronic signature can satisfy a signature requirement.

What the provincial laws actually say

The core rule is simple. Information or a record is not invalid or unenforceable only because it is in electronic form. Where the law requires a signature, an electronic signature satisfies that requirement, as long as it meets the conditions the act sets. In Ontario's act, for example, an electronic signature is information in electronic form that a person has created or adopted in order to sign a document, and that is in, attached to or associated with the document.

Two other ideas show up in every statute. The first is consent. No one can be forced to use electronic documents, but consent does not have to be formal. In Ontario it can be inferred from a person's conduct, such as opening a signing link and signing. The second is reliability. Where the law requires an original or a document that is retained, the electronic version must be reliable and must stay accessible for later reference.

These rules are technology neutral. A typed name, a drawn signature, a click on an I agree button and a cryptographic signature can all count. What matters is that the person meant to sign and that you can show it later.

Documents that still need paper or witnesses

Each statute lists documents it does not cover. The lists vary, so check the act in your province. The usual exclusions are:

Wills and codicils, and trusts created by them. Ontario allows wills and powers of attorney to be witnessed remotely by video, but the will itself still needs to be signed in ink. British Columbia went further and has allowed electronic wills since December 2021, under amendments to its Wills, Estates and Succession Act.

Powers of attorney, to the extent they deal with property or personal care. Rules differ by province.

Negotiable instruments, such as cheques and promissory notes, and documents of title.

Documents that create or transfer an interest in land and need to be registered. In Ontario these are registered through the province's own electronic land registration system rather than through a general e-signature tool. Since 2015, Ontario has allowed agreements of purchase and sale of land to be signed electronically.

Some sectors add their own rules. Certain government forms, court filings and regulated professions may require a specific format or process. If a regulator or court tells you how a document must be signed, follow that instruction.

What makes an e-signature hold up

Legal validity is the starting point. The question that matters in a dispute is evidence: can you show who signed, what they signed, and that the document has not changed since? The Canada Evidence Act and provincial evidence acts have rules for electronic records. In broad terms, a court will look at whether the system that created and stored the record was reliable.

Good practice is to keep four things for every signed document. Proof of intent, meaning the signer took a clear action to sign. Proof of identity, meaning a check that ties the signer to an email address, phone number, access code or ID. Proof of integrity, meaning a way to show the file was not edited after signing. And a timeline of events, with dates, times and devices.

eSora Sign records all four. Every signed document gets a Certificate of Completion as its last page, a tamper seal and an event log, and on paid plans a trusted timestamp from an independent timestamp authority. You can download all of it as an evidence pack, and anyone can check a copy on the public Verify page.

Practical tips for Canadian teams

Pick the identity check to match the document. An email code is fine for most agreements. For higher value or higher risk documents, add an SMS code or an access code you share by phone.

Offer French. Signers in Quebec and across Canada may prefer it. eSora Sign shows the signing page in English or French, and you can preview your email message in both.

Keep the signed file and the certificate together. Do not print and rescan a signed PDF. Store the original download, or keep it in eSora Sign with a retention rule.

Think about where the data lives. eSora Sign stores data in Canada.

When in doubt about a document type, especially anything involving land, estates, family law or a regulator, check with a lawyer before you switch it to e-signature.
