Flatface-
I think you are misunderstanding the central issue to this. An American company paying a third of their Canadian counterparts is setting up to take flying away from Canadian pilots.
An American company that offers meager benefits, typically hires relative low experience pilots, who often pay for their own training, and then work to the bone for next to frack all - will be taking the jobs from pilots who worked and developed experience for years to get a fair paying job with good benefits.
Is it just business? I don't know... seems like a betrayal of Canadian pilots; Canadian workers; Canadian families - Air Canada affiliated or otherwise by Canada's "flag carrier"...
