Should cities make local businesses advertise in English?

In parts of Metro Vancouver, residents see flyers, business signs, and bus shelter ads that are entirely in a language other than English - often Chinese. In a region where more than half the residents have a first language other than English, you can see why a company would feel comfortable advertising in one of those languages. But not everyone thinks that's right. Chak Au is a city councillor in Richmond, BC. He wants to encourage all businesses to advertise in English, so that non-Chinese residents don't feel left out.
