I noted that their gcmap graph uses ATL & CDG as centre points. Hubs for both airlines who want a larger C Series and have stated range is not a factor for their use.
The longest current route operated by a C Series is RIX-DXB, if correct, this represents 2.685mi (2,332nm) real world use. YUL-YVR is 1,995nm or roughly 15% less. It would seem that for real world use, a YUL-YVR use would pe possible, but perhaps not plausible year-round. And YUL-SFO/LAX out of contention.
Still not convinced this plane is right for AC and more of a get out of jail card for Airbus who wants to keep producing A321s so they can't sell anymore A320s for most customers
