Tons of float operators in Canada, not sure what their requirements are. Everyone claims they require 100-500hrs float. As for the 737 type rating, wont do you much good here since most of the FOs hired on 737s have 2000-3000hrs with lots of turboprop time and PIC time. The industry here is such that if you dont want to instruct in the city, you head north to the boonies. Its not as bad as it seems, infact I know some float guys that fly 8 months a year and make almost twice what a westjet FO makes. Good luck in your search, and as prang one pointed out, this is a land of immigrants, although I was born here so I dont know how I am an immigrant and you're free to find your own opportunity, just dont steal mine
LOL.
Good luck!
