::::::::::::Well, there you're wrong; look up the Motor Vehicle Act and know that it's in all provincial driving exams (important when you consider the number of people from drive-on-the-left countries who have moved here).   
 ::::::::The British Columbia Act and the subsequent British Columbia Constitution Act, I think it's called, which are federal legislations mandating BC as a province, may state that English is the operating/DBA language of the province, but I don't think there are any provincial statutes mandating an official language-of-state. it may be that the Office of the Speaker proscribes the language to be used in the House; but other languages are not unknown - a recent controversy over Jenny Kwan making an address in Chinese proved controversial, but I think the upshot was that there is no official language, otehr than the de facto status of English, not even in the House. Certainly the BC government does not publish, other than in federal-related documentation, anything in French (IRs in BCGNIS have two listings, one in French, one in English, but that's because they're also federally-registered names). Daicaregos, it may help you to understand this is a thorny issue in BC, and the use of Colombie-britannique is always controversial (it's also in etymological error, as BC is named indirectly for the Columbia River by way of the Columbia District, and the French names of both use Columbia", not "Colombie", which refers to Colombia in South America...also in French it's typically in lower-case, not caps, though apparently there's a wikia Wiki convention about that...the usual French abbreviation in French is "le c.-b." or similar)...I have to reboot, more later.
