Can a CPA firm license its data to AI companies?

Short answer: Often, yes. A Canadian CPA firm can usually license firm-authored material, such as procedures, checklists, de-identified review trails and workflow, to AI buyers. It can't license confidential client information without consent under the CPA Code (Rule 208 in Ontario) and its engagement letters. Tax returns, SINs and CRA material stay out entirely.

The confidentiality rule is narrower than many partners assume, but stricter than most US guides suggest. Here's the practical line.

Short answer: often yes, for the right records. Canadian CPA firms can usually license material the firm wrote itself, such as procedures, checklists, review-trail patterns and workflow, once client-confidential and personal information is scoped out. What they can't do is hand over client files without consent.

What does the CPA Code allow?

In Ontario, Rule 208 of the CPA Code of Professional Conduct restricts disclosing confidential client information, or using it for a third party's advantage, without the client's consent. Other provinces have equivalent rules, and in Quebec professional secrecy applies too. The working rule: if it came from a client, assume it's confidential.

Do engagement letters matter?

Some letters add data-use or confidentiality terms of their own. They can be stricter than the Code.

What can a CPA firm usually license?

  • Close and year-end procedures and checklists
  • Review notes, once de-identified and with client facts removed
  • Internal SOPs and training material
  • Practice workflow templates and timing

What can't it license?

  • Tax returns, slips and CRA material
  • SINs, business numbers and banking details
  • Client payroll and your staff's HR files

Does privacy law still apply to de-identified records?

Even de-identified, records can hold personal information. PIPEDA covers cross-border transfers, and Quebec's Law 25 adds a privacy impact assessment step.

What should a CPA firm do next?
