Can you put client data into ChatGPT? Only in a way Canadian privacy law allows: on a business plan that does not use your data to train models and gives you contractual protection, only for purposes your clients would reasonably expect, with the minimum information needed, and with your privacy policy explaining that you use service providers. Pasting identifiable client details into a free, personal AI account is the risky default to rule out.
If you have not given your team an approved AI tool, there is a good chance some of them are already using their own. It usually starts innocently: summarizing a long client email, drafting a proposal, cleaning up meeting notes. The problem is that the client's name, contact details, project history, or health information may now be sitting in a personal AI account your business does not control.
The answer is not to ban AI. It is genuinely useful, and bans rarely work. The answer is to decide which tools are allowed, what information can go into them, and how you explain it to your clients.
Which Privacy Laws Apply to Your Business?
For most private-sector businesses in Ontario, the main law is the federal Personal Information Protection and Electronic Documents Act (PIPEDA). Ontario does not have its own general private-sector privacy law, so PIPEDA applies to personal information you collect, use, or disclose in the course of commercial activity.
- Health practices: health information custodians in Ontario, such as clinics and regulated health professionals, are covered by the Personal Health Information Protection Act (PHIPA), which sets stricter rules for personal health information.
- Clients in other provinces: Quebec's private-sector privacy law, strengthened by what is commonly called Law 25, and the private-sector laws in Alberta and British Columbia can apply to information about people in those provinces.
- Where the law is heading: federal privacy reform is back. Bill C-36, the Protecting Privacy and Consumer Data Act, was introduced in June 2026. It would create a new private-sector privacy law, add transparency requirements for automated decision systems including AI, require businesses to assess privacy risks before sending personal information outside Canada, and allow much larger penalties. As of September 2026 it is still a bill, not law, but the direction is clear.
What PIPEDA Expects When You Use an AI Tool
PIPEDA does not mention ChatGPT or any other AI product by name. It sets principles that apply to any tool, including AI. The ones that matter most:
You Stay Accountable
When you send personal information to an AI provider, that provider is acting as your service provider, and you remain responsible for the information. PIPEDA expects you to use contracts or other means to ensure the provider protects it at a level comparable to your own. In practice, that means using a business plan with data-processing terms, not a personal account.
The Office of the Privacy Commissioner's September 2026 guidance on choosing service providers is a useful checklist here: find out whether the provider uses your data to train its AI or for its own purposes, identify the countries where the data is processed, and spell out each party's privacy responsibilities in the contract.
Use It Only for Purposes Clients Would Expect
Personal information should only be used for the purposes it was collected for, or for purposes a reasonable person would consider appropriate. Using AI to draft a reply to a client's question is easy to justify. Feeding your entire client list into a tool to profile customers for an unrelated purpose is not.
Share the Minimum Necessary
Most AI tasks do not need names, addresses, or account numbers. Removing or replacing identifying details before you paste text into an AI tool is one of the simplest and most effective habits you can build.
Protect It Appropriately
Safeguards must match the sensitivity of the information. For AI tools, that means business accounts controlled by the company, multi-factor authentication, sensible retention settings, and removing access when someone leaves.
Be Open About It
Your privacy policy should explain how you handle personal information, including that you use third-party service providers and that information may be processed outside Canada. PIPEDA does not prohibit processing personal information in other countries, but it expects you to be transparent about it and to protect it by contract.
Know What Happens If Something Goes Wrong
If personal information under your control is involved in a breach that creates a real risk of significant harm, you must report it to the Office of the Privacy Commissioner of Canada and notify the affected individuals. You also have to keep a record of every breach, even the ones that do not meet that threshold.
Consumer AI Accounts vs Business Plans
The single biggest decision is which kind of account your team uses. The details vary by provider and change often, but the pattern across the major AI tools is consistent:
| Question | Consumer Accounts (free or personal paid plans) | Business Plans (e.g. ChatGPT Business, Claude Team, Microsoft 365 Copilot, Gemini in Google Workspace) |
|---|---|---|
| Used to train AI models? | Often yes by default, unless the user turns it off in settings | No by default, under business data terms |
| Who controls the account? | The individual employee | Your business: an administrator manages access and removes it when someone leaves |
| Contract terms | Consumer terms of service | Business terms, usually with a data processing agreement |
| Retention and security controls | Limited, set by each user | Admin-controlled retention, single sign-on, and multi-factor authentication options |
Always confirm the current terms for the specific plan you buy, including whether a given feature is covered. Some providers also let business customers choose the region where data is stored, but options vary: OpenAI, for example, offers Canadian data storage on its Enterprise plan but not its Business plan, and Anthropic's Claude plans do not currently offer it. If your clients or contracts require Canadian data residency, get it confirmed in writing before you sign up.
Regulators are paying attention to how AI companies handle personal information. In May 2026, the federal Privacy Commissioner found a complaint about ChatGPT's handling of personal information to be well-founded and accepted OpenAI's commitments to address it, while the commissioners in British Columbia and Alberta found those commitments did not meet their provinces' consent requirements.
A Simple Traffic-Light Rule for Your Team
Staff need a rule they can remember in the moment. This one works for most small businesses:
| Colour | Type of Information | Rule |
|---|---|---|
| Green | Public information, your own marketing copy, general questions, internal documents with no personal information | Fine on any approved business AI tool |
| Yellow | Client names and project details for drafting emails or proposals; routine employee information for HR documents | Approved business plan only, minimum details necessary, human review before anything is sent |
| Red | Health information, SIN, banking or card numbers, passwords, ID documents, information about children, legal matters, anything you promised to keep confidential | Never, unless a specific system has been approved for that purpose |
Five Steps to Put in Place This Month
- Choose an approved AI tool on a business plan and pay for it. The realistic alternative is not "no AI." It is staff using personal accounts you cannot see or control.
- Write a one-page AI-use policy. List the approved tools, the traffic-light rule, and the requirement that a person reviews AI output before it goes to a client.
- Turn on the right settings. Confirm model training on your data is off, set sensible chat retention, and require multi-factor authentication.
- Update your privacy policy. Mention that you use service providers, including AI tools, and that information may be processed outside Canada.
- Keep a short register of AI tools. Note which tools touch personal information, for what purpose, and where the data is stored. It takes an hour and makes client questions and breach response far easier.
Health, Legal and Financial Practices: Go Further
If you handle personal health information, legal matters, or financial records, the bar is higher. Under PHIPA, a custodian remains responsible for any agent that handles personal health information on its behalf, so a written agreement with the AI provider is essential, not optional. Many professional regulators have also published guidance on generative AI for their members. Check your regulator's current guidance, prefer tools that offer Canadian data residency where your clients or contracts require it, and consider a privacy impact assessment before rolling out anything that touches client files.
Frequently Asked Questions
Is ChatGPT PIPEDA compliant?
No AI product is PIPEDA compliant on its own, because compliance depends on how your business uses it. A business plan with contractual data protections, used for purposes your clients would reasonably expect, with minimal personal information and an updated privacy policy, can fit within PIPEDA. Pasting identifiable client details into a personal free account generally does not.
Do I have to tell clients that my business uses AI?
PIPEDA requires openness about how you handle personal information, including your use of service providers and processing outside Canada, so your privacy policy should cover your AI tools. Beyond the legal minimum, telling clients where you use AI, such as meeting transcription or drafting, builds trust. For sensitive uses like recording meetings, ask first.
Do AI tools have to store our data in Canada?
PIPEDA does not require Canadian data residency. It requires comparable protection through contracts and transparency with the people whose information you hold. Some clients, contracts, and sectors do require data to stay in Canada, especially public-sector and some health settings, so check your obligations before choosing a tool.
