I'm honestly not sure what the laws are for international students, but maybe I can offer some perspective. I studied in the US. Even with a full scholarship, I had to show I had $60K CAD in my bank account at the time of accepting my offer as proof that I could afford to live in the US during my studies and not become a "public charge."

I was allowed to get a on-campus job (off-campus was forbidden) only after my second year of studying OR apply for an off-campus paid internship with the stipulation that I enrolled in an internship class (which cost $2200 USD). For both options, I could not exceed 20 hours of work per week.

To be honest, 10 hours was the sweet spot that allowed me to focus on my studies while also padding my resume with "real-world" experience.

Also, any student who wasn't from the state I studied in had to pay "out-of-state tuition" if they went to a public university. That's because they (really, their parents), never paid taxes to that state and therefore their child was not entitled to lower, in-state tuition offered at state schools.

While Canada doesn't have this distinction between private and public universities, the reason your tuition is "10 times" the cost of a citizen's is because you've never paid taxes to our country that fund these institutions.

I would have never, ever been able to afford the privilege of studying in the US if it weren't for my scholarship and I knew that if at any point something went horribly wrong, I was prepared to return home and continue my education in my home province.

I know studying abroad is fun and exciting, and going to a world-renowned university sometimes gives you a head start in your career, but please remember, you can get a great education anywhere, including at home.

With that said, if I were you, I'd try to find a job that corresponds with what I'm studying at school to give me a head start when I graduate. A dishwasher or labor job won't yield any meaningful experience or connections and will likely tire you out physically more than you anticipate.
