You can apply the permanent residency through Immigration Canada.
And after couple of years when it comes though apply Air Canada, Jazz or Westjet and start as an F/O with $35000 salary.
I do have CASA ATPL but I can't work there because of the same problem. I need Australian permanent residency to be able to work there and low salary.
However, if you want to instruct students at flight school for a year, then you can get a visa for that. There's no conversion for the instructor rating. You will have to do the whole course.
