A few things...

Soap is a huge oversight.

You have far less water than you need to use all those things and nothing to filter / screen the big stuff out to make boiling easy, to say nothing of a water filter. No way of capturing rainwater that I can see either. If you're going to use bleach to purify, get a few syringes and needles. Light and will help measure accurately.

I'd stick a bunch of the stuff in paper (sugar, flour etc) into ziplock bags (light, handy, especially once stuff is open and spills happen - perhaps include a straw to suck the air out between usings / compact stuff and it might help with keeping the smell down and not attracting animals) and bring more baby wipes. Those go pretty fast, when you're "showering" with them.

I personally have a light nesting set of pots / pans I bought off of craigslist and use them instead of dishes.

Get a small, light cutting board. I started filling cleaned mio bottles with oil, I find I use quite a bit less and it's a lot less messy / wasteful. But a liter of cooking oil can find a use. If you're going to keep the big bottle, take a spare cap that firs, mark it so you don't get confused and punch a tiny hole in it.

Bottled propane is a pain in the ass to find in times like these and the containers are heavier.

A coleman liquid fuel stove can run on auto gas. Not great for it in the long term (i.e. daily use for months), but it can be cleaned, and it's very efficient for the weight. Lots of old timers will tell you it's impossible, they used leaded gas and they would foul quickly. Some people take injector cleaner with them and put a tiny amount in each fill. If you do get a liquid stove, I'd also store a spare gasket or two, just as those are known to fail and it's a pain in the ass to figure out a replacement in the field. If you live in a very cold area (i.e. yes, fuck your winters), some gelled gasoline is a good idea to start them. A liter of gas, 1 medium egg white (absolutely no yolk), salt, blend carefully without flame is easy to make and keeps a while if kept cold. They make a commercial product too.

Also...a .22 cleaning kit should be the right size for most of what you need to maintain the liquid fuel stoves - and you should pack a care kit for your rifle.

My liquid coleman sits under a seat in my van all the time, so weight of it, etc is no biggie. Pack it full of stuff, like a lighter, spatula, etc - and if you can find one, a griddle that fits inside.

If you do stay propane, then maybe an adapter for a full size tank. Hose / regulator won't weigh that much. You might want to look into thermos cooking for the rice to save fuel (and perhaps pack some oatmeal), the weight of a wide mouthed thermos bottle would easily be worth the fuel you'd save.

I don't know how you'd survive a sask winter. Instead of mylar sheets which rip, go for mylar coated car window shades - I got a bunch at Army and Navy for under $2 each and they have survived quite a few years. A lot more durable as they are attached to some sort of semi stiff backing and they have straps. I've used mine a bunch, even sitting on them by a fire every time I go camping (you stay really toasty) and they're mostly still going strong. Toss em in a sleeping bag if you're cold) Pushpins can be used to secure them to the insides of most vehicles. Not a perfect solution.

Plain mylar? Noisy, teary, annoying. I don't think it's ever survived a trip. You can buy it for cheap from aliexpress if you are going that route though.

A pot scrubby is another good idea. Sometimes you don't have any fine sand to clean pots with.

I personally take one of these mesh basket organizers. Folds up flat, is fairly light and is great for drying pots, pans, organizing stuff, etc.

These things in case it's not clear.

I've also begun to pack a mouse trap. Light weight and can be a huuuge bullshit saver. And an axe/hatchet.
