I just wanted to answer his second point, his major point, about the possible relationship between a mismatch in the permanent immigrant program and the rise of undocumented workers. I think that's a very good insight. I think the market—because I am an economist—will attempt to correct it.
If you have a points system that doesn't really reflect the demand for workers, you're going to have an unhappy world. You're going to have highly skilled Chinese coming here who can't practise their professions, because either they're not in demand or they lack credential recognition. And you're going to have employers who don't have enough workers, who will take a chance on hiring an undocumented worker to build a house, either here or in Toronto.
So this is the connection.
