I guess one of the points I would make there is that as we've seen the immigration numbers change over the years, there has been a definite attempt to increase the proportion of immigrants selected on the basis of economic criteria and reduce the family-class component. I think that has been done without any evidence that this is really a priority from the point of view of the overall design of the program.
While we've been doing that, we've also been changing the economic selection criteria to reduce the emphasis on skill level and increase the emphasis on immediate labour market concerns. That may actually have reverberations for family-class immigration of the future. That probably represents more of a threat to the long-term economic benefit of the program than increasing family-class immigration.
