That is a great question. I had to do significant research into this, as I had a choice of going to the 777 is YYZ as a DEFO in Jan, or wait until
SEPTEMBER for the 744 US. This was a tough choice but it seems that the insurance issue could be a bait and switch. Get you in the door for Canada, than say "sorry". Currency conversion risk, right-to-work issues, taxes, etc, the list goes on. I had to end up passing on the Canada offer. Hopefully that left open a spot for a HKG guy to get a base

.
Still patiently waiting for USAB...sighhh...
If anyone gets confirmed US guys based in Canada that ARE receiving cigna, please share.
