Toronto has passed a law a few years ago to ban smoking in all restaurants. After the law is in effect, people become very cooperative and only smoke outside the restaurants. In fact, the business in the food industry has not gotten any worse because of that, it seems that more and more people seem to go out to eat. Smokers here don't complain about the law, they respect the right of non-smokers. This is something that HK will never be able to do.
