LSO Rules for Law Firm Websites: What You Can Actually Say

Short answer: under the Law Society of Ontario's advertising rules, everything on a law firm's website counts as marketing, so it must be demonstrably true, verifiable, not misleading and professional. In practice: no "specialist" unless you're LSO-certified, a past-results disclaimer beside any results or dollar amounts, client consent before naming clients or cases, fee ads that say what's included, and no superlatives dressed up as awards. None of that stops a site being persuasive. It just has to be precise.

Here's the homepage I see most often: a boardroom stock photo and a headline promising aggressive, experienced, results-driven representation from Toronto's top lawyers. Two of those four are exactly what the Law Society's own pre-publishing checklist tells you to look for. The other two are just tired. It's why every law firm website design I do starts from the rules, not the adjectives. Here's the site element by element, including where the rules are looser than you'd think.

Which rules actually cover a law firm website?

Rule 4.2-0 counts your firm name, trade name, letterhead, business cards and logo as marketing, and the Rules' own commentary names a lawyer's website expressly. Rule 4.2-1, the core of the lawyer advertising rules in Ontario, then requires marketing to be demonstrably true, accurate and verifiable; not misleading, confusing or deceptive; and in the public's best interest and professional.

The commentary gives two lists, which are easy to blur:

• May contravene: dollar amounts or success rates without a disclaimer, claiming superiority, raising expectations, implying you're aggressive, disparaging others, and emotional testimonials.
• Does contravene: advertising services you can't competently provide, bait and switch, hiding that you refer clients out for a fee, not saying whether lawyers or paralegals do the work, and awards that aren't bona fide.

Paralegals follow their own rules and Guideline 19, so this post is about lawyers.

Can you call yourself a specialist, an expert, or say you specialize?

• "Specialist" or "C.S.": only if the Law Society has certified you (Rule 4.3-1), and By-Law 15 bars anyone else from a designation a reader might reasonably take as certification.
• "Specializes": in Law Society of Ontario v. Rothman (2021), the Tribunal's Appeal Division held that accurately saying a firm specializes in an area doesn't breach Rule 4.3-1. The verb isn't the noun. This feels pedantic because it is. It isn't settled, though: the LSO checklist still flags "specializing in".
• "Expert": not in the rule text, but the checklist flags it too. Risky rather than banned.

The commentary expressly lets you name practice areas, say your practice is restricted to one, and describe your experience accurately. "Practice restricted to family law. Called to the bar in 2011." Safer, and more convincing.

Can you put testimonials and Google reviews on a law firm website?

Yes. The rules don't ban testimonials, whatever some compliance pages say. Emotional ones may contravene, so "she explained every step and called back the same day" sits somewhere different from "he saved my family."

The bigger issue is confidentiality: under Rule 3.3-1, even the fact that someone consulted you is confidential, so a testimonial that identifies a client needs their informed consent. The same applies when replying to Google reviews: confirming the reviewer was your client is already a disclosure. More on asking for reviews, where Google also forbids incentives.

Can you publish case results and settlement amounts?

Yes, with a condition. An amount recovered or a success rate may contravene unless it comes with a statement that past results aren't necessarily indicative of future results, and that amounts and outcomes vary with the facts of each case. The commentary says "accompanied by", so it goes beside the number, not in the footer.

The duty of confidentiality applies even when others share the knowledge. The commentary does say it may not apply to facts that are public knowledge, but that is a grey area, so get the client's authorization before featuring a case, even a reported one.

Can you say you're the best, aggressive, or award-winning?

• "Best", "#1", "aggressive": the commentary reads "awards" and "rankings" broadly enough to include superlatives, which is where "Toronto's top" lands, and implying you're aggressive is on the may-contravene list.
• Awards: fine if they genuinely reflect your performance through a reasonable evaluative process, weren't paid for, and still comply when you cite them. An award you paid to receive is a receipt with a nicer font.
• Honours: honours for professional or civic service from government, the Law Society or a professional organization don't contravene the rule, provided they're genuine and the reference isn't misleading.

What are the rules for putting fees on a law firm website?

Rule 4.2-2 allows fee advertising if it's reasonably precise about what each fee covers, says whether disbursements, third-party charges and taxes are extra, and you strictly stick to it.

• Residential real estate: under Rule 4.2-2.1 the price must be all-in except HST and listed permitted disbursements such as land transfer tax, and must say those are extra. A purchase price must also include acting on one mortgage, and a sale price must include discharging the first mortgage. That covers prices returned through a website form too (a specific quote based on an actual assessment of the deal is different, provided you fully disclose the expected disbursements), and the extras can't hide in small print.
• "No win, no fee": contingency marketing triggers Rule 3.6-2.2, which requires a general maximum contingency percentage published on your website, easily accessible.
• Second opinions: marketing them is prohibited outright (Rule 4.2-1.2).

What do your firm name, domain and About page have to get right?

• Say what you are: Rule 4.2-1.1 requires every piece of marketing to identify that you're licensed as a lawyer, and the commentary says you must expressly state whether lawyers, paralegals or both provide the services. On a website, that means a line in the site-wide header or footer, plus any standalone landing pages, not a single sentence on the About page.
• Don't look bigger than you are: the LSO's marketing checklist flags it, and its guidance says lawyers practising in association shouldn't present themselves as a single firm, including in how associates are listed on websites. A headline about "our team of dedicated litigators" is a lot of team for two people and a printer.
• Names are case by case: the LSO's current guidance warns that firms often list "associates" improperly, and space-sharing lawyers practising "in association" aren't associates, so "& Associates" with no associates is a problem. But the Hearing Division in Rothman (2019), by a 2-1 majority, accepted "Real Estate Lawyers.ca LLP". Register any trade name with ServiceOntario.
• Domains: I found no LSO rule on them, but a domain is marketing, so I'd apply the same tests. A domain with "best" in it is a superlative with an annual renewal fee.

What about lead-generation services and referral arrangements?

Rule 3.6-7 bars giving any financial or other reward to someone who isn't a lawyer or paralegal for referring clients, and Rule 3.6-7.1 bars doing it indirectly. Referral fees go only to another licensee, under a written agreement, and they're capped.

Whether a pay-per-signed-client vendor fits those rules is a question for the Practice Management Helpline, not me. For what it's worth, I charge a flat one-time build price ($999 for a multi-page firm site), not a cut of signed clients.

Your contact form is a confidentiality question before it's a conversion one

Confidentiality covers prospective clients from first contact, and the Rule 3.3-1 commentary warns that taking in confidential information informally can later stop you acting for another party.

So I build the form around the conflict check: name, other parties, type of matter, and a note not to send details yet. A big empty box labelled "Tell us what happened" is a conflicts problem with a submit button. This refines the "brief description" field I suggested in how small firms get consultations: swap it for other parties and save the story for after the conflict check. The form also brings in PIPEDA.

Why no web designer can make your site "LSO-compliant"

Here's where I argue against my own trade. This isn't legal advice, and I don't answer for your marketing. You do. The Law Society won't give advance rulings on marketing. The fee rules alone have been amended repeatedly over the past decade, and tribunal decisions haven't always agreed on "specialize". Anyone selling an "LSO-compliant website" is promising something the Law Society itself won't.

Check the current text of Chapter 4 of the Rules or call the Helpline at 416-947-3315 (1-800-668-7380 ext. 3315). My job is narrower: to build a site where the compliant version is the default, and to flag every claim, result and fee line for your sign-off.

The rules and good copy want the same thing

Read the rules back and they're a copywriting brief: be specific, be verifiable, say what's included, don't shout. A sceptical prospect trusts "practice restricted to employment law since 2012" for the same reason the Law Society does. It can be checked. "Toronto's top employment lawyer" can't, and everyone reading it knows.

That's how I build websites for Ontario law firms. Want to see your firm's version? I'll design a free demo homepage with these rules in mind from the first draft, before you pay anything, and nothing goes live without your sign-off.

Frequently asked questions

What are the Law Society of Ontario's advertising rules for lawyers?

Rule 4.2-1 says a lawyer's marketing, website included, must be demonstrably true, accurate and verifiable, not misleading, and in the public's best interest. Other rules cover specialist claims (4.3-1), fee advertising (4.2-2 and 4.2-2.1) and identifying yourself as a lawyer (4.2-1.1).

Can lawyers use client testimonials in Ontario?

Yes, but emotional ones may contravene Rule 4.2-1, and because the fact that someone was your client is confidential, you need their informed consent before publishing a testimonial that identifies them.

Can a lawyer call themselves a specialist in Ontario?

Only if the Law Society has certified them (Rule 4.3-1), and By-Law 15 bars any other designation a reader might reasonably take as certification. Certified specialists may use "C.S." or "Certified Specialist" with their area.

Can lawyers post case results or settlement amounts on their website?

Yes, with conditions. An amount recovered or past success needs an accompanying statement that past results aren't necessarily indicative of future results and that outcomes vary with the facts of each case. Public decisions are a grey area for confidentiality, so get the client's authorization first.

Will the Law Society of Ontario review or approve my law firm's website?

No. The Law Society says no department, including the Practice Management Helpline, gives advance rulings on whether marketing complies, and compliance stays with the lawyer.
