Good Morning Michael,
I understand what you want cause I did the same work as you do. I take it you are working for FCA and Skyservice. I worked for MYT and Skyservice. I tried years ago after my first season to go and work for them in Canada. Tried every which way to go but they wouldnt take me cause I needed a visa. I know alot of the skycrew but from what I gather from them you do need the visa. Two years ago I got the chance to work with skycrew on the A330 for a few months it was fantastic. You still have plenty of time to get there in the winter. Talk to your pilots they know as best as anyone. Hope this helps a bits.
cheers
