So about a year ago, I started planning a trip from Montreal to Seattle by plane and back by truck. I kept asking my partner "when can we go? If we leave it too late, there might be snow in the Rockies." "I don't mind snow in the mountains." We went in November and caught the first snow of the year coming down the east slope. Whit knuckle driving! But October should be fine and I would sure have hated to have missed that drive through the Rockies. I was just spectacular.

On the other hand, the prairies. I have been across them many times in each direction and even the first time was too much. By train you can fall asleep safely. From Winnipeg east, you will get some prairie and then the glories of the area north of Superior. From the Terry Fox park, you can see forever across the Lake.

That car idea, however, is worth a look. Then it might be worth the trip across the prairies.

It sounds like you are quitting in Toronto? Would be a shame to come all this way and not see the whole of Canada! By train, plane or automobile.
