Most university programs in Canada do not need a powerful laptop. Note-taking, research, essays, spreadsheets, video calls and browser-based coursework run comfortably on a mid-range machine with 16 GB of RAM and a good battery. The exceptions are engineering, computer science, architecture and design programs, which may require specific software with real hardware demands.
Battery life and weight matter more than most students expect before their first semester. A laptop that gets carried across campus daily and used through back-to-back classes benefits far more from being light and lasting 8-plus hours than from having a slightly faster processor.
Before buying, check your program's specific requirements — some faculties publish minimum specs, and some software (CAD tools, certain engineering simulations) is Windows-only or genuinely demanding, which rules out a MacBook or a lightweight ultrabook for those students specifically.
