This, and the recent TFW changes announced by Alberta are welcome developments in how worker visas and permits are handled in both countries, that is, with greater granularity and control.  It's interesting that Christy Clark is issuing a call to top American tech workers while Alberta is seemingly closing the door.  IMO, what do we need to do in tech is to have open borders at the very highest ranks of tech development and research, but support local tech workers in the more common jobs: application programming, network support and database administration.  Politicians seem not to be aware of these distinctions and think of tech as tech. There are many anecdotal horror stories about abuse of the TFW program and it needs to be better managed.
