As far as I can tell, the push against immigration in Canada is mainly around unskilled workers (which a lot of TFW are) and asylum seekers, but we will see how this pans out.

They're just turning the knob down a little bit because it was pretty high last few years and caused some supply side issues in housing and healthcare.

I'm sure Canada will gladly accept highly skilled engineers.

The push back against immigration is against the way it was exploited by scammers to exploit people and make money from them.

The sort of high educated immigrants of the sort that would work in software engineering will not face remarkable headwinds.
