AI automation for Canadian small businesses: PIPEDA, Law 25, and where to start

For a Canadian small business, PIPEDA and Quebec's Law 25 set the rules for any personal information your AI automation touches. In plain terms: collect only what you need, get consent for how you use it, run a privacy impact assessment before sending data to a US-based AI tool, and tell people when a decision is made by automation alone.

What PIPEDA and Law 25 mean once you add AI automation

Adding AI does not change which privacy laws apply to your business. It changes where your data goes and how decisions get made, and those are exactly the two things PIPEDA and Law 25 care about most.

The Personal Information Protection and Electronic Documents Act (PIPEDA) is Canada's federal private-sector privacy law, in force since 2000. It sets ten fair information principles: identify why you are collecting data before you collect it, get meaningful consent, limit collection to what is necessary, protect the data with appropriate safeguards, and let people access and correct their information.

Quebec's Law 25, the modernized version of the province's private-sector privacy law, is stricter and closer to the European Union's GDPR. It rolled out in phases between September 2022 and September 2024 and is now fully in force. If your automation touches the personal information of anyone in Quebec, Law 25 is the standard you have to meet, and meeting it generally satisfies PIPEDA at the same time.

Does Law 25 apply to a small business?

Yes. Law 25 has no size or revenue threshold and no small-business exemption. It applies to any organization that collects, holds, uses, or communicates personal information in Quebec, and to organizations outside the province that target Quebec residents.

Federally, PIPEDA is the baseline across Canada. Three provinces (Quebec, Alberta, and British Columbia) have their own private-sector laws that the federal government has deemed "substantially similar," so those laws apply locally while PIPEDA still governs data that crosses provincial or national borders.

The practical takeaway for a small business: build to the strictest standard that applies to you, which is almost always Quebec's Law 25, and you are covered for the rest.

The three automation-specific obligations that trip people up

Most of the compliance surprises in AI automation come from three provisions.

Sending data to a US-based AI tool is a cross-border transfer. Most general-purpose AI tools run on US infrastructure. The moment you send a customer's personal information to one, you are transferring it outside Quebec and outside Canada. Law 25 requires a privacy impact assessment before that transfer, plus a written contract with the receiving party and disclosure to the people whose data it is. PIPEDA keeps you accountable for the data and requires you to tell people it may be processed in another country.

Automated decisions carry extra duties. If your automation approves, ranks, prices, or rejects a person based solely on automated processing, Law 25 requires you to inform the person, disclose the main factors behind the decision, and give them a way to contest it. Profiling functions cannot be switched on by default. Once a person is meaningfully involved in the decision, these specific obligations no longer apply, which is one reason a human-in-the-loop design is often the simpler path.

Consent is tied to purpose. Data your business collected for one purpose cannot be quietly repurposed to feed an AI system. Under Law 25, consent must be express, specific, and requested separately for each purpose. If the automation uses the data in a new way, you generally need fresh consent for that use.

PIPEDA vs Law 25: obligations that matter for automation

Where to start: a practical order

1. Inventory the personal information in the workflow. Before you automate, list every field the automation will read, write, or send: names, emails, phone numbers, payment details, anything that identifies a person. You cannot protect data you have not mapped.

2. Locate where each AI tool processes that data. Check whether the tools in your stack run on Canadian, US, or other infrastructure. Anything that leaves Quebec or Canada is a cross-border transfer with its own obligations.

3. Run a privacy impact assessment before connecting personal data to a foreign tool. Law 25 requires a privacy impact assessment before you transfer personal information outside Quebec. Keep it proportionate: a short, documented assessment is enough for a small workflow.

4. Flag any decision the automation makes on its own. If the system approves, ranks, prices, or rejects a person without a human reviewing it, plan for the disclosure and contest rights Law 25 attaches to automated decisions. Keeping a person in the loop is often the cleanest way to stay onside.

5. Check that your consent covers the new use. Data collected for one purpose, such as fulfilling an order, cannot be repurposed to feed an AI system without fresh, purpose-specific consent. Confirm your existing consent language matches what the automation actually does.

6. Put a written data processing agreement in place with each vendor. Law 25 and PIPEDA both expect a contract that limits how a processor, including an AI provider, uses the data, and that requires it to protect the information and delete it at the end of the engagement.

7. Minimize what the automation sees. Feed it only the fields it needs, and use de-identified data where the task allows. For sensitive data, consider a self-hosted platform so nothing leaves your environment.

8. Publish the basics: a privacy policy, a named privacy officer, and a breach plan. Law 25 requires a designated privacy officer whose contact is published, a plain-language privacy policy, and a register of confidentiality incidents kept for five years.

If you want the automation itself to stay inside your own infrastructure, the platform choice matters. Self-hosted tools keep personal data out of third-party clouds, which sidesteps much of the cross-border question. Our comparison of n8n, Zapier, and Make covers which platforms can be self-hosted and the trade-offs involved.

A note on scope

siasola builds AI automation, we are not a law firm. This guide explains the obligations that shape how automation should be designed, but it is general information, not legal advice. For anything involving sensitive data, employee records, or automated decisions that affect people, confirm your specific requirements with a Quebec privacy lawyer and with the primary sources: the Office of the Privacy Commissioner of Canada for PIPEDA and the Commission d'acces a l'information for Law 25.

Handled early, the privacy groundwork does not slow automation down. It mostly means mapping data, documenting a few short assessments, and choosing tools that keep sensitive information where it belongs. That is the kind of scoping we build into every engagement at Siasola's AI automation service. To understand what these systems actually do before you scope one, see our plain-language guide to AI agents, and for the wider picture on Canadian jurisdiction and data residency, read why building software in Canada matters for privacy.
