You are in for a rude shock.
160,000 pts from YYZ with BR.

I fly J/C on that route and am lucky to get around 18,000 per RT.
You are going to have to do a lot of flying to get a RT reward ticket.
Even if you downgrade to Elite its still 120,000.

With the expiration dates on points it is near impossible to redeem LHs if making less than 4 LHs a year on BR.

Don't bother with the upgrade from elite to premium because they are difficult to obtain and the point requirement maakes it a waste.

I'd rather BR did away with the points and cut the ticket prices. Evergreen club is a horrible FF plan and offers no value. I would expect that even if you hope to cash in the miles on Aeroplan you will be sorely disappointed when faced with the $1000+ fees and charges Aircanada adds to reward tickets. I paid approx. $1200 last summer on a YYZ-ZRH-BKK routing. 150,000 miles in the craptastic TG first between ZRH and BKK and J class on AC metal for ZRH-YYZ. Big mistake.
