Welcome to the Forum. I don't want to discourage you, but with your budget, I'd be very tempted to buy used, as getting all of that gear to a decent specification is dam near impossible for $2K CAD.
I'm a fan of Sony's STR-DN1080, which is discontinued by the way. It was introduced about 4 or 5 years ago. I was recently looking for a STR-DN1080 for my Mother to replace her Sony STR-DE598 as she needs to get to HDMI switching for her newer devices (Apple TV, Telus Cable box, & a Blu-ray Player) and Bluetooth Broadcast for headphones. I was also looking for the STR-DN1080 as it has the simplest remote I have ever used; and my Mom is getting up there and gets confused with her current remote. (I've got a STR-DN1050 in the Family Room 5.1 setup, and a STR-DN1060 at the Family Cabin in 5.1. I also have a Denon AVRX-4400H in the Atmos set-up => 5.2.4 in the Games Room, and a Denon 7.1 AVR-S900W in the Man Cave / Junk Room in the basement. Yes I'm an Audioholic, and I know I've got a problem...)
In Canada (yes I'm a proud Canadian) there may be the odd STR-DN1080 around (Best Buy?) at $1000. Best Buy has a open box listed on the Web for $800, and a few open box ones through their marketplace at $770 with a 6 month warranty. Even at such prices it's just too much for your budget.
Frankly, I think Denons are a better receiver than any similar priced Sony. And I have had multiple samples of both. I used to have a 3rd Denon but I gave it to my brother.
The Sub mentioned seems too small for your room, and the Magnat speakers wouldn't even cut it in my garage. The enclosure, is plastic and they are targeted to outdoor patio type applications as they have a splash proof designation (IPX 5).
Below is from their website describing the X160:
"The big sister of the X 130 is equipped with a 165 mm bass-midrange driver. With an extended bass range that delves down to 30 Hz and an upper cut-off frequency of 36,500 Hz, it ensures full music enjoyment regardless of whether it´s used as a monitor speaker directly on a workstation, or as a speaker in a hi-fi configuration on a shelf or sideboard. An efficiency level of 92 dB and a maximum load capacity of 220 watts ensure a high dynamic range. The dimensions, however, remain pleasantly compact: Measuring 186 mm wide and 310 mm high, it is hardly any bigger than an A4 sheet. A weight of 3.3 kg, however, gives you an idea of just how much technology is incorporated in the Symbol X 160."
Frankly I don't believe a word of it They say the frequency response is 30 - 36,500 Hz with a 6.5" woofer and a PET Tweeter. Total Bullsh*t. You'd be wasting your money!
Other will chime in with their suggestions, but I doubt if the speakers and the Sub will get any positive responses.
Take a look at Facebook Marketplace, Craigslist, Kijiji, and maybe you'll find someone selling a whole system for $2K CAD or less. If so, post it here and the gang will chime in if you should go look at it, or walk away.
I hope this is helpful.
