What do students do for work here?

I recently moved here from AB to go to school at U of S, but I was (maybe foolishly) thinking I would be able to find lots of part-time work aimed at making use of students.

After months of searching and applying, I can hardly find anything. Even in food service and retail most places are FT only. I have been looking on Canada job bank and Saskjobs.

Any advice for how/where to find work?
