You may have the impression that this sort of trip is easy and without potential problems. That is not true. Since you are surrounded by vast amounts of water, Quetico produces its own weather, i.e., it can rain for ten days in a row or snow in any month of the year. Excellent rain gear can make the difference in having a pleasant trip or a rotten experience. Even during the summer, rain gear can be useful in case the weather becomes cool and is invaluable in keeping the bugs off.
Wind can be a real bummer.
It's possible to be wind-bound for up to a week on a large lake. It can be a bit disconcerting to notice as you pass between the rollers there is a wall of water extending a foot and a half above the sides of your canoe. No sane person should be on a lake under these conditions. It is a testament to Tim's and my canoeing ability, as well as our obvious insanity, that we came through without any loss of limb or equipment. Everyone hears stories about the number of mosquitoes and black flies one finds in the north country.
