What is the Best route across Ontario (Winnipeg to Mtl)

[Francois23]

I'm doing Vancouver to Montreal. I heard ontario's shoulder are not so good.
What is the best way to go across. I was thinking of going from winnipeg to Nipigon on Hwy 1 (17) then take Hwy 11 to Kirkland lake and then across the border to rouyn-noranda and down to Montreal.
Does that make any sense? where are the best shoulders?
Thanks
