Drumbo, are you still working on the air pass?
As long as the Canada-Europe flight is on a*A carrier you can use the air pass with the folowing issues to bear in mind:
1. Minimim 3 sectors.
2. All confirmble in advance.
3. All collect status miles on your FF plan.
4. Prices are based on distance-starting at 75USD for 400 miles ( if I remember correctly)
5. A connection as in your example will mean 2 coupons.
6. Prcing can be obtained by your airline or TA
7. Flights are changeable without penalty.

Do call the TA and have them give you the prices. Still confused? send me a PM--although I am out of the country--will try answer it.
