It's Richmond, not Vancouver, that's trying to encourage english in the business sphere. The reason is because there are so many chinese only signs that many non-chinese aren't even going into the city and it's hurting the city. I know that I only go into Richmond when I absolutely have to, and there's no reason for me to go. I haven't been there since I quit my last job that was in Richmond over a year ago.
As for the Quebec referendum, the only problem I had with it is no one asked the rest of the country if they could stay. That would've been a VERY different referendum if that happened.
