English-only creative running in Quebec
The Charter of the French Language is not an informal preference — it is a legal requirement that advertising directed at Quebec consumers be available in French. English-only Meta campaigns geographically targeting Quebec create legal exposure and, as a practical matter, underperform with French-primary Quebec buyers who are less likely to engage with English-language product advertising. The resolution is straightforward: Quebec French creative must be produced for any campaign with Quebec geographic coverage, and Meta's language targeting settings must be used to serve the correct language variant to each audience. This is a creative production and account configuration requirement, not a technical complexity. Brands running Canada as a single English-language market have likely been running non-compliant advertising in Quebec if their campaigns cover the province.
