Law 25 for Montreal Businesses: A Compliance Guide

Since September 22, 2022, every business in Quebec has had to protect the personal information it holds and report confidentiality incidents; most of the other obligations have applied since September 22, 2023, and the right to data portability since September 22, 2024. For a Montreal organization, complying with Quebec’s Law 25 is not optional: it is mandatory, and the penalties can reach millions of dollars. Yet many SMBs still do not know where to start.

In this plain-language guide, we explain what Law 25 requires, the concrete steps to become compliant, and the part technology plays in protecting you.

1. What Law 25 requires of a Montreal business

Law 25 modernizes the rules for protecting personal information in Quebec. In practice, it imposes transparency, consent and security on the data you collect. Every business that holds information about its clients or its employees is covered.

The law applies no matter the size of the organization. Compliance that is properly understood protects your reputation as much as your legal position.

2. The key Law 25 obligations for a Montreal business

Several requirements shape compliance. Here are the main ones.

Appoint a person in charge of data protection

Every business has to designate a person responsible for privacy. Their contact details must be published, usually on your website.

Obtain clear consent

You have to explain why you are collecting data and obtain explicit consent. Vague or buried consent is no longer accepted.

Report confidentiality incidents

If data leaks, you have to notify the Commission d’accès à l’information, Quebec’s privacy regulator, along with the people affected. An incident response plan therefore becomes essential.

3. The penalties compliance helps you avoid

Fines can reach 25 million dollars or 4% of worldwide revenue. That is why compliance cannot be pushed aside. Beyond the penalties, it is your clients’ trust that is at stake.

Worth remembering: Law 25 is not only a legal constraint. Applied properly, it strengthens your clients’ trust and becomes a competitive advantage.

4. How technology supports Law 25 for a Montreal business

Compliance rests in large part on technical measures. Here are the most important ones.

Encryption and access control

Encryption protects sensitive data, and access management limits who can consult it. A leak becomes far less likely.

Backups and Law 25 compliance for a Montreal business

Reliable backups and access logging let you react quickly when an incident happens. They also make it easier to prove your compliance.
