Another place you may want to take a look at it is Blue Fox Camp in Algoma. I haven't been myself, but a couple of buddies were there a few years ago and had a great time.
Some other food for thought. A few years back we drove up the James Bay Road. It's a "highway" that runs up the east side of James Bay in Quebec, that's the furthest north you can go by road in eastern Canada. It was constructed to facilitate the building and maintenance of the huge hydro-electric projects up there. It starts in Matagami (9 hours from the GTA) and goes 600km north up to the small outpost of Radisson, where there's a campground and lodge with excellent fishing (Brookies, Lakers and huge Pike) on one of the reservoirs. In between there is nothing but wilderness...one gas station at just past the half way mark....but absolutely nothing else. There are several primitive unserviced campsites along the way, some with gravel boat ramps on lakes (that had good trout fishing too). The reason I mention this trip is, almost every single river or creek we crossed and stopped to fish had Brookies....lots in the 12"+ range.
We just pitched tents along the way, but if you rented yourself a nice RV and towed a tinner, you would have a fabulous couple of weeks of wilderness fishing in relative comfort.
