One minority language that is not suffering from lack of official recognition is Canadian French.
Quebec, of course, was a French colony, while Canada as a whole was an English colony. And French-speaking Canadians are evidently very active politically such that there are a lot of laws to protect the French language. Public schools are offered in both English and French; only children who are already fluent in English may attend English public school. Children who have a home language that is neither English nor French must attend French schools.
An interesting twist is that businesses in Quebec must have French signs which means, among other things, that they may not use apostrophes. You will sometimes see little maple leaves, stars, etc. used instead of apostrophes all across Canada (so that the business does not have to have two different signs/logos).
