Canadian and EU privacy law grew from the same OECD roots, and superficially rhyme: purpose limitation, consent, security, access. The differences that matter to a compliance program sit in the architecture: what triggers the law, which legal justifications exist, what individuals can demand, and what non-compliance costs. Companies serving both markets should treat GDPR as the ceiling and patch the PIPEDA-specific gaps rather than run two separate programs.
| Comparison | PIPEDA | GDPR |
|---|---|---|
| Max penalty | CAD 100,000 (narrow offences) | EUR 20M or 4% of turnover |
| Consent model | Default requirement; implied consent possible | One of six bases; strict standard |
| Breach deadline | As soon as feasible (RROSH trigger) | 72 hours to authority |
| Official texts | PIPEDA | EUR-Lex 32016R0679 |
The five differences that change your program
1. Consent versus lawful bases. PIPEDA requires knowledge and consent for virtually everything, but calibrates its form: implied consent suffices for non-sensitive data in expected contexts. GDPR lets you choose among six bases, with consent defined strictly (opt-in, granular, withdrawable). Practical trap in both directions: GDPR legitimate-interest processing may need consent in Canada; casual Canadian implied consent fails the GDPR standard in Europe.
2. Rights. Both grant access and correction. GDPR adds erasure, portability, restriction, objection, and Article 22 protections. Canadian rights expansion waits on PIPEDA’s successor; Quebec’s Law 25 already grants portability and de-indexing provincially.
3. Penalties. GDPR’s 4%-of-turnover regime has produced ten-figure fines. PIPEDA’s offence fines are minor; the OPC’s real levers are publicity, compliance agreements, Federal Court applications, and the class actions its findings trigger. Do not read the small fine number as low risk: Home Depot, Facebook, and Clearview AI all paid heavily in remediation and litigation.
4. Breach mechanics. GDPR: notify the authority within 72 hours unless no risk. PIPEDA: report to the OPC and notify individuals as soon as feasible when there is a real risk of significant harm, and keep records of all breaches, harmful or not, for 24 months. A joint incident means both clocks run simultaneously.
5. Transfers. PIPEDA’s accountability model travels with the data via contract. GDPR gates the border with adequacy and SCCs. Canada holds partial EU adequacy (2001, reaffirmed January 2024), so EU-to-Canada flows into PIPEDA-covered processing are free; the reverse direction needs your Canadian entity running GDPR transfer paperwork for any EU data it exports onward.
