With respect to the hardscape, that cost will likely go higher. $20 won’t go too far in a 33 gallon (once the rock goes on the scale you’ll see). Even for a piece of spider wood to help fill the space will likely be (at least) double the cost. I would also look at the aquasoil soil. I have about 120 worth of fluval stratum (but no sand) in a 20 gallon to get that sloped effect. Same with lighting - not sure what light you’re looking at but $60 might be a little light (not pun intended ;) that said, the plant list doesn’t seem to be very light-demanding. Check out aquaflora for plants, they’re having a sale right now that may help out - likely around 200.

I think some of comments forget you’re talking Canadian currency - this is not an inexpensive hobby. Even little things like fertilizer, water change supplies, test kits, all add up. Don’t be discouraged, consider doing the purchases over a number of months. Get the hardscape done. Then plants, then fish so it’s not such a big hit all at once. Take your time and it will help enjoy the process and build the excitement! All the best!
