Law 25 and PIPEDA: questions Canadian firms should ask before connecting client data to automation tools

Connecting your CRM, intake forms, email and accounting through Zapier, Make, Power Automate or an AI assistant saves hours. It also copies client personal information into new systems, often hosted outside your province or outside Canada. For a Canadian law firm, accounting practice, clinic or consultancy, that raises a fair question: what do PIPEDA and, in Quebec, Law 25 expect before you switch the automation on?

The short answer: neither law bans automation tools or foreign hosting. Both expect you to stay accountable for the data, protect it by contract, tell people it may be processed elsewhere, and be able to respond quickly to a breach. Quebec adds a formal step: an assessment before personal information leaves the province. This guide sets out the questions to ask. It is general information, not legal advice; check your position with your lawyer or privacy officer, especially if you are in a regulated profession or handle health information under provincial health privacy laws.

Which law applies to you

Most private-sector firms outside Quebec, Alberta and British Columbia fall under the federal Personal Information Protection and Electronic Documents Act (PIPEDA) for their commercial activities. Quebec firms fall under the Act respecting the protection of personal information in the private sector, as amended by Law 25, overseen by the Commission d'accès à l'information (CAI). Alberta and BC have their own private-sector acts, and health information often sits under separate provincial laws.

Federal reform is also in motion. In June 2026 the government tabled Bill C-36, which according to Blakes would replace PIPEDA's privacy provisions with a new act and require a privacy impact assessment before personal information is transferred outside Canada. It was not law when that analysis was published; check its status before relying on either regime.

Question 1: Who stays accountable when a tool processes our data?

You do. The Office of the Privacy Commissioner's guidelines for processing personal data across borders say that an organization remains responsible for personal information transferred to a third party for processing, and must use contractual or other means to provide a comparable level of protection. Comparable does not mean identical, but it does mean you need to know what each vendor promises.

For each automation tool, ask:

• Does the vendor offer a data processing agreement, and have we accepted it?
• What security controls does it describe, and is there an independent audit report?
• Can we limit which staff can see run history and connected accounts?

The same applies to any consultant who builds the workflows. Our guide on what to put in a data processing agreement with an automation consultant lists the clauses worth checking.

Question 2: Where will the data actually be stored?

Many automation platforms store data in the United States. Zapier states on its security page that data is hosted on AWS in the US. Make offers separate EU and US zones, and self-hosted n8n can run on a server in Canada if you are prepared to maintain it.

Foreign hosting is generally permitted under PIPEDA, but the OPC guidelines note that data processed abroad may be accessible to that country's courts and authorities, and that a contract cannot override foreign law. Make a simple list: every tool in the workflow, where it stores data, and how long it keeps run logs. Run logs matter because they hold readable copies of whatever passed through each step. Our article on whether it is safe to put client data through Zapier explains retention in more detail.

Question 3: Have we told clients their information may be processed elsewhere?

The OPC guidelines say organizations should tell individuals, in plain language and ideally at the point of collection, that their information may be processed in another jurisdiction. Under PIPEDA a transfer for processing is treated as a use, so new consent is generally not needed if the purpose has not changed, but transparency is.

Quebec goes further. Since September 2023, Quebec firms must inform people at the time of collection that their information may be communicated outside Quebec. Check that your privacy policy, intake forms and engagement letters say this before a new workflow goes live.

Question 4 (Quebec): Have we done the assessment before data leaves Quebec?

This is the step Quebec firms most often miss. The CAI's summary of the main Law 25 changes (in French) explains that:

• A privacy impact assessment (évaluation des facteurs relatifs à la vie privée, EFVP) is required before acquiring, developing or overhauling an information system or electronic service that involves personal information. A new automation platform connected to client data can fall into that category.
• Before communicating personal information outside Quebec, the firm must carry out an assessment; if it shows adequate protection, the communication may go ahead under a written agreement that meets certain conditions. This applies since September 2023.
• The assessment should be proportionate to the sensitivity of the information.

A Toronto-hosted tool is outside Quebec too, not only a US one. Keep the assessment short and honest for low-risk data, and more thorough for health, financial or legal files.

Question 5: Who is in charge of privacy, and is that visible?

Under Law 25, the person running the business is the person in charge of protecting personal information by default, and may delegate the role in writing; the CAI page says the title and contact details must be published on the firm's website. PIPEDA also requires a designated person accountable for compliance.

For automation, that person should approve new tools that touch client data and own the list of where data goes. If nobody owns that list, workflows multiply quietly.

Question 6: Could we spot and report a breach in time?

Both regimes require breach reporting, with different tests.

Sources: the OPC's guidance on responding to a privacy breach and the CAI's Law 25 summary.

Automations create specific breach risks: a workflow emailing a document to the wrong client, a shared login left active after someone leaves, an AI step that sends a full file to a tool nobody approved. Two habits help. Send failure alerts to a shared mailbox someone checks, and connect tools through firm-owned accounts rather than personal logins. Our guide on what happens to automations when an employee leaves covers the second point.

Question 7: Are we sending more data than the workflow needs?

The simplest protection is minimization. Most triggers pass the whole record to the next step. If the workflow only needs a name, email address and matter number, map only those fields. Avoid forwarding full email bodies or attachments unless the workflow truly needs them, and keep sensitive categories (health details, identity documents, banking information) out of general-purpose automation tools unless you have assessed that tool specifically.

A short checklist before go-live

• List every tool in the workflow, where it stores data and its log retention.
• Accept each vendor's data processing terms and file them.
• Update privacy notices to mention processing outside your province or Canada.
• In Quebec, complete and file the assessment before data leaves the province.
• Connect tools through firm-owned accounts and route failure alerts to a shared mailbox.
• Name the person who approves new tools and keeps the breach record.

How Flow Mesh helps

Every engagement starts with a first call and an NDA, then a stack audit scoped in writing before it starts, giving a verdict on every tool (keep, configure, consolidate or replace) and a map of where client data flows. Builds are quoted in writing after the audit and done inside your own accounts, and a DPA is available on request. The legal assessment itself stays with your lawyer or privacy officer.

Key takeaways

• PIPEDA and Law 25 allow automation tools and foreign hosting, but your firm stays accountable and must protect data by contract.
• Tell clients, at collection, that their information may be processed outside your province or Canada.
• Quebec firms must assess before personal information leaves Quebec and put a written agreement in place.
• Know where every tool stores data and how long its logs keep copies, so you can assess a breach quickly.
• Federal reform (Bill C-36) may change the rules; check its status with your lawyer.
