A typical student job pays minimum wage, around 8-10$/ hour. So if you find a job that pays you 10$/ hr for your max 20 hrs per week, you are looking at $200 a week and $800 a month. After taxes, that leaves you with around $550-ish at the end. That probably wont be enough to cover your rent and food.
also consider that getting that part time job is not so easy, especially if you are:
1. a new comer to canada
2. your english is not as good
3. you have no real world work experience
Also, you will be competing with tons of other students. So dont expect to get a job the same day you land. You could very well go months when looking for your first job.
If you work more hours, then you would not be studying. So what would be the point of paying all that tution if you are not going to get an education.
The easiest way to manage finances is to get into a program that offers co-op. On your co-op work terms, you can make better than minimum wage working full time and save enough to pay part of you tution fee in the following semesters.
There's a reason why you are supposed to prove you have the financial means to pay for your education when applying for a visa as working while studying is not a very easy thing to do. Even domestic canadian students can barely pay their tution while working part time.
I would suggest figuring out your financial situation before coming here so you dont have to rely upon work, atleast for the duration of your studies. You can always work with your PGWP and pay back if you borrow money from a bank as a student loan.
P.S. savings interest rates a pretty shiite at the moment. Dont expect anything better than 1.5%-2%
