Why are Ontario tech CEOs so worried about Amazon HQ2 in GTA? Supposedly steal 'their' employees. Because 1) tech pays lousy and have been so for a long time; 2) highly unstable employment, most workers are contractual, not a career path' 3) can't compete with Amazon. 
S0-called 'tech', meaning computer/network R&D&operations, in Ontario is tiny stuff, second rate and pays lousy. No way Amazon will do it here. And if it does it's because it intend to hire 95% from overseas.
