Yea I probably shouldn't have used a quote there. The number ranges from 20% to 50% depending on which part of vancouver you look at. Point is that they aren't a minority there.
Assuming your parent meant "not a small minority". I don't have numbers in front of me, but having lived in and near Vancouver most of my life, I wouldn't be surprised if close to that percentage had Chinese origins. Regardless, it's enough people that it's certainly worth candidates' time to consider them.
As an average across Vancouver, are Chinese really 25%+ of the population?
