I used to have aspirations to move to Canada and I know folks who have tried to hire SREs in Toronto. While that post may sound hyperbolic, it is for all intents and purposes accurate. You can’t build an SRE team in Toronto because the talent pool is too shallow. It really is that bad. The story repeats over and over. The degree to which the US captured the Western countries through its dollar system is actually quite astounding and should terrify people.
