Tip 1) Don't bother converting to a Canadian CPL.
I have both JAA and CAN and started my flying career there. You will need at least 500-1000hrs to get a job on a piston twin as co-pilot and before that you will be expected to work the ramp. They are very traditional with regards to progression and you will be expected to pay your dues.
Tip 2) I wouldn't hold out too much hope of getting a piston twin job in Europe. As the point has been already made, the place is not awash with operators like other parts of the globe.
I have 800 hours on PA31's (and well over 1000tt) and am still looking in the UK with no luck yet. Its pretty dry out there.
