The problem in immigration is that the performance of immigrants has deteriorated over time, and this reflects the performance of both family class and economic immigrants, not to mention refugees. The government has been trying to deal with the whole issue of selecting the best economic immigrants by looking at the selection criteria. So they recognize the problem and they're trying to deal with it.
On the family class, though, the problem is that they're not subject to the same sort of screening. They don't have to pass language tests. They don't have the labour market readiness. So you're always going to have bad performance from family class immigrants.
I don't see a problem with giving family members extra points on adaptability, as the government does, but to bring people in just because they're family, I think you're just asking to have a larger and larger number of people who are going to be marginalized in the Canadian labour market and society.
