Hi. I've recently made a PC build before Halloween last year. The one I have would be too much as I use a 8 core Ryzen 3700X CPU along with 16GB RAM.
I think you would need to upgrade the motherboard and the CPU. Go with a 6 core CPU from Intel or AMD. No need to get the 10th gen Intel or the new AMD chips as you could go with previous gen CPU chips at lower prices.
The graphics card may need an upgrade. There is no need to buy a $1000 CAD graphics card. Do check for compatibility with the motherboard.
The RAM could be saved and maybe the PC case and cooler. Again, do check for compatibility.
PCPartPicker along with some Youtube videos has been helpful with researching PC builds, prices and such.
It is not known what the budget for the upgrades is. Is the currency in USD, CAD, AUD?
