Electronic Signature Law and Legality in Canada

Electronic signatures are legally recognized in Canada under both federal and provincial laws. The Personal Information Protection and Electronic Documents Act (PIPEDA) governs federal use, while individual provinces and territories have their own laws that support the enforceability of electronic signatures in most business transactions.

Federal and Provincial Framework

Federal Law: PIPEDA

At the federal level, PIPEDA, in effect since 2004, confirms that electronic signatures:

• Are equivalent to handwritten signatures
  
  
• Are court-admissible
  
  
• Can be used for most commercial and personal agreements
  

For an electronic signature to be considered secure under PIPEDA, it must be:

• Unique and distinctive
  
  
• Under the sole control of the signer
  
  
• Capable of verifying the signer’s identity
  
  
• Tamper-evident through secure technology
  

Provincial Law: UECA

Most Canadian provinces (except Quebec) follow the Uniform Electronic Commerce Act (UECA), which provides a consistent legal framework for electronic documents and eSignatures. Quebec uses its own legislation, the Act to Establish a Legal Framework for Information Technology.

Both frameworks are:

• Media-neutral – recognizing electronic documents as legally valid
  
  
• Minimalist – allowing flexibility in technology used
  
  
• Designed to treat electronic and paper documents equally
  

What Counts as a Legal Signature in Canada?

The term “electronic signature” in Canada covers:

• A typed name or email footer
  
  
• A scanned image or digital drawing of a signature
  
  
• A password, code, or PIN
  
  
• A digital signature generated using public key cryptography
  

Canada does not distinguish between standard, advanced, or qualified electronic signatures like in the EU. It recognizes a single tier of legally valid eSignature—provided the signer’s intent and identity can be verified.

Unique Case: Is a Thumbs-Up Emoji Legally Binding?

Yes. In June 2023, a Canadian court ruled that a 👍 emoji constituted a valid electronic signature. The case was based on the Electronic Information and Documents Act, 2000 (EIDA), which defines an eSignature as any electronic action linked to a document with intent to sign.

Because the emoji followed a long-standing pattern of prior agreements between the two parties, the court ruled that the response represented intent—and therefore, it formed a legally binding contract.

When eSignatures May Not Be Accepted

While eSignatures are valid for the majority of documents in Canada, some exceptions apply. These documents typically require handwritten (“wet ink”) signatures:

• Wills and codicils
  
  
• Trusts from wills
  
  
• Certain powers of attorney
  
  
• Divorce and adoption documents
  
  
• Promissory notes
  
  
• Some real estate contracts
  
  
• Consumer disclosures required by law
  
  
• Court documents submitted to provincial or federal courts
  
  
• Documents requiring notarization
  

You should also confirm requirements with public bodies, as different government departments and agencies may enforce their own standards for eSignatures.

Government of Canada’s Digital Signature Policy

The Canadian government provides guidance for secure electronic signatures, including:

• Verification of digital certificates
  
  
• Ensuring keys are within their validity period
  
  
• Confirming the certificate is not revoked and traces to a trusted authority
  
  
• Implementing long-term validation measures such as cryptographic timestamping
  

These practices help ensure trust and integrity in sensitive or long-term records.
