For most Quebec consumer practices, yes: build the French page first and the English page second. Statistics Canada’s 2021 census reported French as the first official language spoken by 82% of Quebecers, so most prospects phrase the question in French. Whether engines treat the two languages differently is unmeasured, so Firm AEO treats the order as a priority call and the language effect as something to test.
Firm AEO has covered Quebec twice: article 145 and the testimonial ban, and the wider Canadian rules around CASL and Law 25. Both mentioned French answer pages in a line. This post is the full language question: which language leads, how the two pages should be structured, and how to find out what each engine can actually retrieve. Firm AEO is a marketing company, not a law firm, and the firm’s own counsel decides what it publishes.
- Statistics Canada’s 2021 census reported French as the first official language spoken by 82% of Quebecers and English by 13%, so a consumer-facing Quebec firm’s likeliest prospect asks the question in French.
- No published study has measured how ChatGPT, Perplexity, Gemini or Google AI Overviews treat French-language legal pages against English ones. Every claim that one language wins is untested, which is why a Quebec firm should run its own bilingual test.
- The structure that avoids the usual failure is two complete pages at separate URLs, each written in its own language with its own direct answer, linked to each other with hreflang. A machine-translated mirror adds a page without adding a retrievable answer.
- Article 145 of the Code de déontologie des avocats and the Charter of the French Language apply to a Quebec firm’s content in both languages. The firm’s ethics counsel and legal counsel decide how, not Firm AEO.
Which language do Quebec prospects actually search in?
Most Quebec prospects search in French. Statistics Canada’s 2021 census reported French as the first official language spoken by 82% of Quebecers and English by 13%, with 46.4% of the population bilingual according to CBC’s reading of the census release. A prospect with a legal problem usually describes it in the language they think in, which is French for roughly four in five people.
Two cautions apply. The census measures language spoken, not the language of an AI prompt. And the English-speaking minority, about one million people, is concentrated in the Montreal area, so a Montreal firm serving anglophone and allophone clients may see a very different mix from a firm in Saguenay. Firm AEO treats the census as the starting prior and the firm’s own intake data as the correction.
Do AI engines treat French and English legal pages differently?
Nobody has published a measurement. Firm AEO searched for a study comparing how ChatGPT, Perplexity, Gemini, Google AI Overviews or Copilot retrieve French-language and English-language law firm pages and found none. The Quebec agency guidance that exists, such as a December 2025 post from bofu.ca, argues for French-first structure on legal and commercial grounds and states no retrieval figures.
That leaves one defensible position. A French prompt is most likely to retrieve French pages, because the question’s wording matches the page’s wording. How often an engine answers a French question from an English source, and the reverse, is a property each firm can measure for its own prompts in an afternoon.
How should a bilingual Quebec firm structure its pages?
A bilingual Quebec firm should publish one complete page per language at separate URLs, each opening with its own self-contained 40 to 75 word answer, and connect them with hreflang annotations and visible language links. The French page is written for French readers, not translated line by line from the English one.
The reason is retrieval. An engine lifts a passage, so a page whose first paragraph is a stiff translation of an English answer gives it a weaker passage to lift than a page written in the idiom a Quebec reader uses. Terms of art should follow Quebec usage, such as délai de prescription for a limitation period, because the engine matches the vocabulary of the prompt.
- One URL per language, for example /fr/ and /en/ paths, never a language toggle that changes content on one URL.
- The same lawyer names, spellings, bar admission and address on both pages, so the firm reads as one entity.
- Each page answers the same question set, but the French version is written first, not back-translated.
- Schema, headings and FAQs in the language of the page, with inLanguage set correctly.
What do the Charter of the French Language and article 145 add?
Both apply regardless of which language leads. Final provisions of Bill 96, which amended the Charter of the French Language, took effect on June 1, 2025 for commercial advertising and trademarks, according to a June 2025 DLA Piper summary. Law firm summaries describe the rules as reaching websites and online advertising, but Firm AEO did not find Office québécois de la langue française guidance that spells out how they apply to a law firm’s pages.
Article 145 of the Code de déontologie des avocats bars testimonials in advertising in either language, so an English page does not escape it. A Quebec firm’s legal counsel and ethics counsel decide how both rules apply. Firm AEO treats them as constraints on the content plan and does not interpret them.
How do you test what each engine retrieves in each language?
Run the firm’s ten most common client questions twice, once in French and once in English, across ChatGPT, Perplexity, Gemini and Google AI Overviews, with three logged-out runs per prompt. Record whether the firm is named, which competitor is named, the language of every cited URL, and whether a cited English page answered a French question. That is 240 runs for ten questions and four engines.
The result is a table of language by engine, and it settles the order of work with the firm’s own data instead of an agency’s opinion. Repeat it quarterly or after a major page change, since engine behaviour moves.
| Engine | French prompts: firm named | English prompts: firm named | French prompt answered from an English page | Action if the gap is large |
|---|---|---|---|---|
| ChatGPT | x of 30 | x of 30 | x of 30 | Strengthen the French page’s opening answer |
| Perplexity | x of 30 | x of 30 | x of 30 | Check which directory cited, in which language |
| Gemini | x of 30 | x of 30 | x of 30 | Check the Google Business Profile language |
| Google AI Overviews | x of 30 | x of 30 | x of 30 | Check hreflang and indexing of the French URL |
When should an English page lead instead?
An English page should lead when the firm’s own data says its clients ask in English: a Montreal practice serving expatriates, immigration clients, cross-border commercial work or the anglophone minority. The census prior fits a broad consumer practice and fits a niche practice badly, so the intake form’s language field and the bilingual test outrank the provincial average.
A federal practice area such as immigration or tax may also draw prospects searching in other languages entirely. Firm AEO covered that pattern in its immigration post. The principle holds for Quebec: lead with the language the target prospect uses, written natively, and cover the second language with its own complete page.
Is a French-only site enough for a Quebec law firm?
It can be for a firm whose clients are overwhelmingly francophone, since 82% of Quebecers report French as their first official language. A firm with anglophone, allophone or out-of-province clients gives up retrievable answers by skipping the English page. The bilingual test and the intake form’s language field show which case applies.
Can a Quebec firm just machine-translate its English pages into French?
It can, but the result is usually a weaker answer passage than one written in Quebec French, and engines lift passages. Terms of art differ, for example délai de prescription. Firm AEO recommends native drafting reviewed by a lawyer who practises in French, and the firm’s counsel approves what is published.
Does hreflang make AI engines cite the right language version?
Hreflang tells search engines which page serves which language, and Google documents it for search results. No published study shows whether ChatGPT, Perplexity or Gemini use it when choosing a cited page. Firm AEO treats it as correct hygiene, not as a retrieval guarantee.
Do the Barreau du Québec advertising rules differ between the French and English pages?
No. Article 145 of the Code de déontologie des avocats applies to the lawyer’s advertising whatever the language, so a testimonial barred on the French page is barred on the English one. The firm’s ethics counsel decides how it applies.
