If I can make a suggestion....take the hwy 17 route through Sault Ste Marie to Nakina. Assuming you're coming from the GTA, it's only about an one hour longer than hwy 11 through North Bay (15 hrs vs 14 hrs). However, it's infinitely more interesting. The stretch between SSM and Wawa is probably one of the most scenic roads in Canada between Cape Breton and the Rockies. Plenty of rivers that have Brook Trout through there...Chippewa, Pancake, Speckled Trout, Agawa, Sand, Old Woman, Michipicoten...just need to hike in a bit from the hwy to the better spots. Be sure to stop at Voyageur's Lodge in Batchawana Bay for Lake Superior smoked Whitefish and awesome homemade apple fritters...makes for a great picnic at the falls on the Sand R. or on Old Woman Bay. The White Fang Motel in Wawa is a good spot to hang your hat for the night.
Frankly, once north of Temagami, I personally find the hwy 11 route boring....flat and nothing but jack pine..
