mustbethesims4 Sure, I can find something for under 900 CAD. What do you think of this one?

Its graphics card is capable of running all current Sims 4 content on ultra graphics settings, and it has enough memory and storage for Sims 4 and regular use, including multitasking. It's only on sale for a few more hours though (maybe), so if it's what you want, don't wait.
I checked Best Buy Canada, Amazon Canada, and Memory Express as well, and I don't see anything else with equivalent hardware for under $850. But there are a handful of good options up to $900, so if you don't like the Acer, tell me why and I'll list some other laptops to consider. In that case, please also let me know whether you'd be willing to get an open-box unit and from which stores.
