Some people don't want to continue in their fields but can take adjacent jobs that were never available to them back home. I mean a physician can join the United Nations or WHO, or something, if they have a PR to a "1st world" country, they would have better allocation into these positions than if they applied from back home, because donor countries get bigger slices of the pie, and after naturalization, their income either doubles or triples, again because they are citizens of a donor country. I still think that Canada benefits, maybe not from a licensed doctor/pharmacist or what have you, but from the high taxes these individuals pay. CEC argument used right!!!
