I was recommended Chinook Helicopters.I would recommend them.They do loads of conversions and if they like you they may hook you up with work.
The earlier you can get here the better.
I came now to scope out a good place to start as I am bringing my family over.
There is definitely demand here, Its nice to be wanted and I only have 1500hrs.
Call Chinook now as they are super busy. There is alot of study material online.
Try the transport Canada website.Half the publications they use here are
available there. Goolgle PStar for a good start in regs.
Luck
