Quebec Law 25

Also known as: Law 25, Bill 64, Loi 25, Quebec privacy law, Act to modernize legislative provisions as regards the protection of personal information

Quebec's Law 25 is the province's sweeping modernization of its private-sector privacy law, adding breach reporting, privacy impact assessments, stronger consent rules, data portability, and penalties of up to $25 million or 4% of worldwide turnover.

While much of Canada waited on federal reform, Quebec simply went ahead. As a result, it now has the strictest privacy regime in the country, and it applies to any business handling Quebecers' personal information.

Quebec Law 25, explained at three levels

At home

Think of Law 25 as house rules for anyone who borrows your belongings. A business that collects your personal information in Quebec must say why it wants it, use it only for that purpose, keep it safe, and destroy it when the purpose is done. If it loses your data in a way that could seriously hurt you, it has to tell you and the provincial regulator.

At work

Law 25 is the set of amendments that modernized Quebec's private-sector privacy act. It applies to any organization that collects personal information about people in Quebec, wherever the organization is based. It requires a named person in charge of privacy, published governance policies, specific consent, breach reporting, and impact assessments. Businesses care because fines are steep and the rules reach well beyond Quebec's borders.

Real-world examples

At home

Sophie, who lives in Montreal, noticed that a new fitness app had all its data-sharing settings switched off by default. When she looked into it, she learned that Law 25 requires privacy-protective defaults. She turned on only the features she actually wanted.

At work

Thomas runs IT for a Toronto-based retailer with stores in Quebec. To comply with Law 25, his team completed privacy impact assessments for its US-hosted customer database, updated the privacy policy in French and English, and set up a breach register. The work also helped them prepare for federal reform.

How it compares

Law 25 is considerably stricter than PIPEDA, and many national businesses now use it as their baseline.

For analysts

If you operate anywhere in Canada, I'd build your privacy program to Law 25's standard and treat other provinces as easier cases. Running one strong program is cheaper than maintaining a patchwork, and federal reform is moving in the same direction.

History & origin

Quebec has long led on privacy: its Act respecting the protection of personal information in the private sector, passed in 1994, was the first private-sector privacy law in North America. Bill 64, which became Law 25, was adopted in September 2021 and phased in over three years. The first obligations took effect on September 22, 2022, including mandatory breach reporting and designating a person in charge of personal information (by default, the CEO). Most requirements arrived on September 22, 2023, including privacy impact assessments, privacy by default, transparency about automated decisions, and the new penalty regime. Data portability followed on September 22, 2024. The regulator is the Commission d'accès à l'information. In my view, Law 25 quietly became Canada's de facto national standard, because few businesses want to run two privacy programs.
