Laptop for university

Hi all! I'm starting university this fall as a computer science student in Canada, and I'm looking for a laptop that's under 1000 CAD I'm open to refurbs/ used it should be small and lightweight ( like not more than 14 inches screen size) 2 in 1 preferably At least 16 GB Ram and 512 GB SSD Not a MacBook. Everyone I know is recommending me a MacBook but I prefer windows Software.

I don't know that much about laptops so some help would be much appreciated. Thanks in advance!
