I just wanted to add that I like the idea the professor had because, in fact, assisted relative class used to be a category under the previous immigration act, whereby having a Canadian citizen or a permanent resident sibling automatically gave the skilled worker 15 points, I think, and that made a huge difference in the qualification of that person. Perhaps that could be a way to facilitate helping a sibling come to Canada.
