For hygienic reasons, it would be advisable to bring your own sleeping bag. On a canoe trip it's difficult to avoid the portages. The places where there are fast moving rivers or dams that are not navigable in a canoe. Then, the canoe and your packs must be carried overland, to an adjoining lake or river that is safe to resume paddling once again. For obvious reasons, you want the lightest equipment that you can find, and the most comfortable pack.
Outdoors equipment is quite costly.
It is best to rent it first, make sure that you enjoy canoe tripping and then, think about investing in some of your own. Do not take an old, canvas tent. At the outfitters rent the higher end models. You will not be required to carry all of the equipment yourself. This should leave just enough space in your backpack for a change of clothes.
