Yes, its a code share that i cant find via air canada's site.

Its a miami layover with many long layover options to canada.

Option 2, is land via neighbouring to the south airport and transfering to canada there...this too is much cheaper.

And since no flights are easy for me, another three hours via usa is peanuts in a total 17+ hour flights.

Carol, thanks the heads up... its a once you know, you know question... i just didnt know...
