What changed?
On June 12, 2026, the Supreme Court of Canada released reasons in Société de l’Acadie du Nouveau-Brunswick v. Canada (Prime Minister), 2026 SCC 22. The appeal concerned whether New Brunswick’s constitutional language guarantees require the province’s Lieutenant Governor to be able to understand and communicate in both official languages when performing the functions of the office.
Core holding
By a 6–3 majority, the Court allowed the appeal. Chief Justice Wagner, writing for the majority, held that appointing a Lieutenant Governor of New Brunswick who cannot understand and communicate in both official languages infringes section 16(2) of the Canadian Charter of Rights and Freedoms.
The majority emphasized New Brunswick’s distinct constitutional status as Canada’s only officially bilingual province. It interpreted section 16(2) alongside section 16.1, which recognizes equality of New Brunswick’s English and French linguistic communities, and concluded that the Lieutenant Governor is an institution of the province’s government for this purpose.
Remedy
The Court restored declaratory relief in part rather than quashing the appointment. In practical terms, the decision clarifies the constitutional requirement for the office going forward while leaving implementation to public authorities.
Dissent
Justices Rowe, Karakatsanis and Jamal would have dismissed the appeal. The dissenting reasons said the Charter provisions create a regime of institutional bilingualism in New Brunswick, but do not impose a personal bilingualism requirement on the Lieutenant Governor.
Why it matters
The decision is a significant official-languages and constitutional-law ruling. It may affect how federal appointment advice is framed for New Brunswick’s vice-regal office and how courts analyze the relationship between institutional bilingualism, personal office-holders, and New Brunswick’s specific Charter guarantees.
