There seems to be a trend in the migration towards Canada of top physicists. It has been announced that Nobel Laureate Anthony Leggett will be Mike and Ophelia Lazaridis Distinguished Research Chair at the University of Waterloo. He follows the footsteps of another Nobel Laureate Carl Wieman, who earlier bolted Colorado University for University of British Columbia. However, unlike Wieman, Leggett still retains his position at the University of Illinois. It appears that he's having a joint appointment with Waterloo, spending 2 months a year there.
Hey, I guess if you're a Nobel Laureate, you can probably write your own ticket. Still, it certainly appears that universities in Canada are in a very aggressive period of recruiting well-known physicists for their institutions.
