That being said, I don't want to give AC any ideas, as I'd wish they'd keep the CR9's to routes under ~1200 miles.
At some point in the past the E90 was fairly common on YYC-YYZ, but no longer, so I was surprised that it showed up. OTOH, we might see the A223 on the route at off-peak times. Although right now it shows up on YYC-YUL and of January or early February. This said I have not checked YYC-YYZ.
