As above from mttachi, aeroplan points (but note, no Q miles) posted quickly, inexpensive rental car from Avis easily arranged at buttonville (no heavy airport concession fees); very convenient if you are headed to Markham/eastern suburbs. (But Air Canada gets my "business" for the rest of the year. Can't beat the AC value of hot breakfast, MLL lounge access, and flexible standby scheduling . . . of course, on Aeroplan award tickets.)
