If you are willing to drive to the western Quebec, there are tons of great places: James river, Le Verendrye come to mind. I've heard great things about Lake Superior Park as well.
But I hear you...Algonquin, Killarney, French River, etc. are being done to death because of their proximity to Toronto. Still beautiful places, but I'd now rather do their treks in the Fall when all the weekend warriors have packed away their gear. I hate having to put 2 or 3 portages between me and my put-in just to get some solitude.
I find that I plan most of my week-long things after Labour Day: still warm days and water, but cool nights for sleeping. Few bugs and fewer people!
