I agree that each trip will be different... still there are basic items that need to be considered. I use this ultralite canoeing list to make sure the basics are there and add onto it if necessary. In a generic sort of way, this was LightJay's 12-pound pack.

For a general planning guide, take a look at Kevin Callan's The Happy Camper... it covers general camping needs and leans towards canoeing.
Good luck and don't forget to report back on how horribly unprepared the first canoe trip turns out to be... jest kidding but really, the first canoe trips are often the worst and after the first few you develop a much thicker skin and thousands of black flies biting every hour becomes normal.
