A French Canadian interpreter is a specific request, and most agencies fill it with whoever is on the French list. That interpreter learned French in Paris or a US classroom, and will spend a Quebec deposition decoding the witness before translating them. Our office is in New York; our French Canadian interpreters grew up with Quebec or Acadian French and work across the country, in person near you or by phone and video the same day.
The demand sits in three places. New England's former mill cities, Manchester, Lowell, Worcester and Waterbury, still hold a Franco-American generation now in its seventies and eighties whose first language is French and whose English is fading with it. Broward and Palm Beach counties fill each winter with Quebec snowbirds, and a share of them end up in a Hollywood or Fort Lauderdale emergency room. And US litigation with a Quebec party produces depositions of French Canadian witnesses wherever the case is filed.
Quebec French is spoken, not read. A witness under oath in Quebec French uses tu where a French textbook expects vous, drops syllables, and uses anglicisms that do not mean what the English word means. Acadian French from New Brunswick and northern Maine, and the chiac of Moncton, differ again. An interpreter who stops to decode is no longer keeping pace with the record. We ask where the speaker is from and assign on that.
Most French Canadian court work is civil: a commercial dispute with a Quebec supplier, a cross-border custody matter, an insurance claim after an accident on I-87. The witness often speaks serviceable English and the attorney books an interpreter anyway, because a deposition transcript in a second language is a gift to opposing counsel. Several states certify French court interpreters through the national oral exam; where a court requires that credential we match it, and confirm the interpreter also works comfortably in Quebec French. Prism is a private agency, not a court-appointed vendor.
Two patients need one. The Franco-American elder in a Manchester nursing home whose English has thinned with dementia until only the French of childhood is left, and the Quebec snowbird admitted to a Florida hospital in February with a cardiac event. A federally funded hospital must provide a French interpreter at no cost to either, and a bilingual nurse pulled off the floor is not that. We send an interpreter who speaks the patient's French, in person for a diagnosis or a discharge plan, by video for a follow-up.
The Quebec-born spouse at a green card interview is the routine case: someone who works in English every day and would still rather answer questions about their marriage in French. The interpreter's job is to render the answer without polishing it, which is harder than it sounds when the question and the answer both come fast. We send a neutral French Canadian interpreter briefed for USCIS work, and we remind couples that one spouse cannot interpret for the other at their own interview.
Canadian federal documents, a passport, a citizenship certificate, a police certificate from the RCMP, come bilingual and need no translation. New Brunswick paperwork is usually bilingual too. Quebec is the province that issues in French only, and since the 2022 language law, English versions are rarer still. So the documents on our desk are Quebec's: the copy of an act of birth or marriage from the Directeur de l'état civil, a divorce judgment from the Superior Court of Quebec, a notarial marriage contract or will drawn up by a Quebec notary, which has no exact US equivalent and needs a translator's note, a CEGEP diplôme d'études collégiales or university transcript for an I-140. Quebec civil status forms carry marginal mentions and a woman's birth surname after marriage, and a translator who Americanizes either has introduced an error. We keep the issuing authority as printed, translate every stamp and margin, and deliver a signed Certificate of Translation Accuracy; the full service is at certified translation.

Our only office is in New York, and our French Canadian interpreters work nationwide. For in-person work we assign someone based in or near the city. These are the areas where French Canadian work is concentrated; the full list of 288 cities is below it.
Prism Linguistics is rated 4.6 out of 5 across 67 client reviews for its interpreting and translation work in the United States. That is the company-wide figure; we do not publish a separate rating per language because there is no honest way to measure one. If a French Canadian assignment ever falls short, tell us and we put it right.
