Population growth is going to slow down, though. The natural increase rate is already dropping, indications are that will go negative by 2030. Furthermore with increased development in the third world immigration demand will also be lower. Whereas now demand exceeds the quota, in the coming decades we may have problems with the quota not being filled. Canada's population a hundred years from now won't be that much bigger than it is today (maybe about 10-15 million more).
Montawa, or Montawall if you want to include Cornwall, may never happen.
If growth in Ottawa & Montreal continue as a narrow tube along the highways (as had happened along autoroute 15 north of montreal) and in no other directions, it could happen. Ottawa is growing mostly westward & southward, though, not southeast along the 417 (there's a good amount of growth right now in Embrun & Casselman but that's already tapering off).
