That's a very difficult and complicated question. I'm not sure I'm sufficiently expert in that area to make a very detailed comment, but I should note that the granting system is very different in Canada from that in the U.S. and Europe. The money is spread much more thinly among many more people. This can also be a barrier to bringing top scientists into the country. The opportunity for large grants to do the most exciting research is often limiting within Canada.
