We did that route two years ago. We went in reverse, went up Hwy 400 to 69 and stayed at Grundy Lake Prov Park (well laid out for Rvs and trailers) Killbear Prov Park is a gorgeous area but depending on what you are travelling in limits you to sites. We continued north to Sudbury and down Hwy 6 to Manitoulin and stayed in the Sheguiandah area. Great fishing, boating, and touristy things to see and do. Then took the ferry across to Tobermory. As stated before need to reserve in advance and it is pricey I recall it was in the $250 range for truck and trailer (price measured by the foot). There is an excellent fish and chips restraunt at the ferry terminal along with gift shop, beautiful native art for sale. Going up the Bruce, very scenic, lots of campgrounds especially closer to Tobermory, we stayed at Summer House Park on Miller Lake just a few Km from town. Lots to do in the area (hiking, tours, biking, scuba, canoe and boating etc). Algonquin Park is hge, we always stayed at Mew lake but there is about 10 camping areas there not including if you are going off the beaten trail. Excellent fishing. If travelling along the 401 (Brighton), there is the Presquille Prov Park, we go there every summer, swimming, biking, hiking, birding. Around 1000 Islands we stay at Ivy Lea KOA which is on the Parkway, 1000 Island cruise, Bolt Castle. City of Kingston just down the highway, night life, Pennitentary Museum, Fort Henry, shopping and restock the fridge. There is also a KOA in Kingston if planning to stay a couple of days. I could go on and on.
