There have been points in history when it was the U.S. that graciously welcomed talented individuals displaced by intolerant, anti-intellectual, or dangerous regimes, and reaped the social, technological and economic rewards. I do not think it hyperbolic to say that this flow is now in the throes of reversal. An investment on this front made by Canada today will be a signal heard around the world and pay off richly in the years and decades to come.
