They would need to run a few daily widebodies to make that concept work.
Summer widebodies -
AC 144 - arrives in YYZ @ 1702
AC 010 - arrives in YYZ @ 1837
AC 156 - arrives in YYZ @ 0530 (red eye)
AC 137 - arrives at YYC @ 1000
AC 009 - arrives at YYC @ 1114
AC 151 - arrives at YYC @ 2044 (1835 departure at YYZ)
