The Canadian tech industry is either unable or unwilling to compete for these skilled workers.  Companies such as Google, Apple, and Facebook attract the talent by offering premium wages, outstanding employee benefits, excellent personal networking,  and the opportunity for personal development.  The favourable taxation works is also a significant US advantage.  While the major US hubs are more expensive to live, Toronto and Vancouver are quickly approaching those levels.  Yet an initial salary of $150M or more is standard in the States, in Canada it is an exception.  So I suspect the information really is as the article states 'anecdotal'.  There may be a short term boost for Canada, but the best and brightest will move where the work is most challenging and interesting and the rewards are best in class.  Rather than rubbing their hands in glee at the misfortune of the States they should be deciding on the best way to compete on an ongoing basis.
