There are lots of folks in southern Ontario who hang. I would see if there's anyone near you who could let you give a hammock a try. I've seen you on "winter trekker" and know that you understand that to get quality and comfort you sometimes have to spend some $$,,same thing applies to hanging. There are allot of folks on "hammock forums" who turned to hammock camping specifically because they had back issues on the ground. Sleeping in a hammock cured that. Sleeping in a hammock will definitely improve your options for finding a place to camp,,the best thing is once your through the learning curve, and there is a learning curve, you get the same comfort/lay in the hammock everywhere you set up. Have a look at Shugs 10 part series for new folks and also have a look at Jeff's " To The Woods" site. Good luck
