Just noticed that the AC130 YYC-YYZ Friday Oct 3 3:15pm flight is served by E90???

With tons of consultants and oil commuters flying home from Calgary to Toronto, this flight is normally served by a 321 (174 seats).
But this Friday it is served by a tiny E90 (97 seats)!?!?

Do the people at Air Canada not know how to make money? Like why even allow the E90 to fly this flight? It should be served by a A321 or a 767.

At T-5 days, the flight's inventory is:
J/0 C/0 D/0 Z/0 P/0 R/0 Y/3 B/3 M/0 U/0 H/0 Q/0 V/0 W/0 S/0 T/0 L/0 K/0 G/0 A/0

Sorry for ranting, but this just means I have to fly home later.... lol.
