BIll 101 in Quebec mandates that all signs must be either in French only, or have French more prominently displayed than English. This is provincial legislation that contradicts the constitution of Canada, but is allowed under provincial use of the Notwithstanding clause, which allows short term renuable exceptions to the constitution if you don't mind coming off as a jackass, and intolerant of the rights of others.

This rule is enforced by provincial jackbooters who go around issueing tickets etc...

All this Fench and English stuff is getting more an more tenuous as increasing segments of the country speak neither language well.

The Conservative party, that has such a sensible line on guns and other maters, is in favour of more power to individual provinces and is in favour of the notwithstanding clause use on maters like gay mariage (me too). Which is why it is assumed there may be a basis for a minority Conservative, Quebec nationalist government federaly. It's always a nose-holding exercise up here, though the overall result isn't bad at all.
