If you are looking for a more general answer, I would say that through the Canadian government's research chair initiative which has been under way for a number of years, our Canadian universities have been able to recruit Canadians who had been working abroad and who were sufficiently drawn by the Canada Research Chairs Program to leave their job abroad and return to Canada. Furthermore, we have been able to recruit foreigners, that is non-Canadian researchers who saw in this program an opportunity to carry out more stimulating and interesting research work than they were doing in their own country.
Last year, I went to Germany. My colleague at the Max-Planck Institute expressed to me his disappointment at having lost some German researchers who had decided to immigrate to Canada to take advantage of the Canada Research Chairs Program. These were young researchers, generally between 35 and 45 years of age.
