It is my first time filling my tax. I am not sure if I should have done it for the previous year. I arrived in Canada (with work permit) in 27 Oct 2023. How to proceed?

Is there a way of filling both 2023 and 2024 at once? Also, my spose came with me but she has no job until now, not sure if I can consider her a dependent, and in that case, does she need to have a individual tax filled?
