The pattern for many Hong Kong immigrants is to have the mother and children live in Canada while the father works in HK.The family doesn't declare the foreign income in Canada.
So they enjoy the benefits of a low tax HK income. And they get all the nice things that go with living in high tax Canada while not contributing to it -free healthcare, subsided University, safe communities, clean environment, low income benefits.
It's so common it has a name, satalite family/astronaut dad.
This isn't a good deal for Canada and Canadians.
