[B]#1. I -think- an openjaw is where I book ONE ticket that is YYC -> YYZ and YYZ -> YYC, and where I book ANOTHER ticket that's YYZ -> LHR and LHR -> YYZ ... Right?</font>
No. What your described is end-to-end ticket which means you are using 2 tickets to get to your final destination. Open jaw means that you fly into one city and out of another, provided that the distance between those two cities is shorter than the distance from the origin to the destination and v.v.

Yes, provided that the fare that you're flying on is eligible for Q miles. I think you meant "Aeroplan points" or did you put "errorplan" on purpose?

...That routing is looking expensive any way that I calculate it. Any other ideas?!</font>
It'll probably be cheaper if you go to LHR instead but you don't get the double miles.

No fare restriction as long as it usually earns Aeroplan miles. So the lowest you can book is N class. [Z is no good because it earns 0 miles]
