From what you have shared, roads in Canada clearly had a different view of this, since for one they never had large power like the US roads.
I have no practical knowledge of railroading in Canada beyond what you have shared.
But here, crossing the Appalachians, big articulated locos and lots of them was the answer for many roads.

Lastspikemike CPR built some 0-6-6-0 pushers around 1900 for the Big Hill at Kicking a Horse Pass, where the Spiral Tunnels are now. They were interesting in that the engines faced each other under the center of the boiler. They were later converted to a successful 2-10-0 design which lasted pretty much to the end of steam if I recall the data correctly.

Yes, you explained that before. Those are not big or powerful locos compared to Yellowstones, Big Boys, Alleghenys, Challengers, Chesapeakes (2-8-8-2's) and the like.
