I guess there are part time jobs everywhere. Only thing to remember is not to fall into "All work and no studies, thereby breaking
the rules". There may be a problem in future then. All good if one sticks to 20 hours during session and full-time during breaks.
Best wishes on finding suitable work at Saskatoon.
Official break is always summer from your school it is for 4 months you can work as much as you want and make enough for next tuition fee . But don't expect that you can make lots of money while study , doing part time job . You can make enough for living expenses in part time job. Some cities like Toronto there is lots of cash jobs available if you can find that one , you can make some money towards your tuition .
