LSO advertising rules and AI marketing: what law firms need to know
The Law Society of Ontario's marketing and advertising rules apply to AI-surfaced marketing exactly as they do to a website or billboard. That means no outcome or success guarantees, no improper specialist or expertise claims, and testimonial handling within the restrictions. Compliant AI marketing is entirely achievable — it just has to be built that way from the start.
Do the LSO rules apply to AI marketing?
Yes. The rules govern how a licensee markets legal services, regardless of the surface. Content created to influence AI answers is still marketing, so the same requirements apply to it as to any other advertising a firm publishes.
What should firms watch for?
- No guarantees of outcomes or success — the rules prohibit them.
- No improper claims of being a "specialist" or "expert" unless the applicable certification supports it.
- Testimonials and endorsements handled within the LSO's restrictions.
- Accurate, non-misleading descriptions of services and results.
How do you keep AEO work compliant?
Put a compliance review gate before anything publishes. Every answer page, schema description, directory listing, and third-party mention should be checked against the rules before it goes live under the firm's name. Marketing that survives regulator scrutiny is the only kind worth doing in a regulated field.
Frequently asked
- Is this legal advice?
- No. This is general information about marketing compliance, not legal advice. Firms should confirm specifics against the current Law Society of Ontario rules and their own compliance judgment.
- Can an AI-written answer page break the rules on its own?
- Yes — if it makes a prohibited claim, it's non-compliant regardless of how it was produced. That's why human compliance review before publishing matters.
