from Akula's reply, I'd guess that he is a base camper.  Cooking over a fire works ok for that style of canoe camping.

Me, I travel every day but 1 - last few years, that's 1 layover day out of 11 or 12 days in, covering 130 to 150 miles or so, with lots of portages.  I don't have the time to "cook", not the desire to "cook" on a canoe trip.  All I ever do is boil water, the only exception being maybe to cook fish over a fire on the one layover day.  If I took time to "cook", I'd have to alter my plans, shorten my loop, spend less time paddling - don't want to do that.  "Cooking" over an open fire is not a part of why I go to Quetico.   I might have a small fire in the evening to burn trash, or I might only do that every 3rd day or so - minimul wood needed for that.  If its been raining steady for the last three days, I don't bother at all.  At camp, I want to relax, not "work" to gather and cut and maybe split wood.

So a stove - the small and lighter the better - is the way I go.
