I wouldn't worry to much about putting in cargo (especially if you do it during the summer). I have picked up two cats at Dulles International airport that came over from Bahrain (in the Middle East). They both had a layover in London and had to change planes, but their biggest issue was jet lag and getting used to colder climates.
Especially if it is a direct flight to Calgary you should not have any problems with it.
If we keep working on this I am sure we can figure out a way to get Coda up to Saskatoon.
