All excellent advice. I'd pay particular attention too the good rain gear and sleeping bag/pad when you get your gear.
Weight is always a consideration. You can save plenty by using multi-purpose items and wearing synthetic clothes.
Your gear will evolve over time. Trial and error and personal preference will be your guide. I'd rather bring too much stuff the first time, than be short and uncomfortable. As long as you can carry your gear and keep up, it's just part of the learning curve.
I did the ultra-light thing during my backpack days. Part of the allure of canoe camping was the ability to bring along certain creature comforts that you would never haul on a long hiking trip.
Depending on the person, those could be fancy coffee pots/solar showers/camp chairs etc.
Some items are necessities, not luxuries. I wouldn't go on a trip without a good sleeping bag suitable for time of year. On that line, better to have to un-zip, than shake and shiver all night.
Same with rain gear. Another item I wouldn't go without is a decent tarp.
A large tarp for meals/fire is nice, but even a smaller one used with your tent sent-up can be a comfort in nasty weather.
My 2 creature items are my Byer mosquito hammock and the solar shower. The hammock is a nice place to read/write and nap, even doing duty under tarp as emergency bivouac.
Solar shower is nice after a few hard days paddling /portaging. Nothing beats a hot shower/clean clothes and a good meal IMHO before hitting the sack. In cold weather the quick dip doesn't really do the trick.
I know it's time when I can't stand to sleep with me

The British had it right, just because your in the wilderness, you don't have too live like savages
