On December 12, 2022, the Office québécois de la langue française notified the Town of Mount Royal that it would lose its status as a recognized bilingual town since it no longer meets the demolinguistic conditions set out in the Loi sur la Charte de la langue française.
However, please be informed that at its January 24, 2023 meeting, the Town Council will adopt a resolution to maintain its status as a bilingual municipality. Section 29.2 of the Loi sur la Charte de la langue française, states that, following the adoption of this resolution, the bilingual status of the Town of Mount Royal will be maintained.
