two English cents
Perhaps this comment has already been made in French, which I wasn't able to read; if so forgive me please.
My short answer is that I believe that the board is intended for an international audience rather than a local one, and that this is as the readers and (perhaps more to the point) the advertisers wish. English is simply the most universally used language around the world, and of visitors to the board. Communicate on the board in French, and fewer readers will understand what you are saying. That is a practical reality, not a value judgement.
Certainly Montreal would lose much of its charm for many of its visitors if it were not French in character! This is not an attempt to subvert the local culture.
