International students in Canada can work unlimited hours in two ways:
On-Campus Jobs: No limit on hours for jobs on your school campus.
Freelancing: Work unlimited hours for foreign clients as it's not considered Canadian labor.
Note: Canada🍁has made the 24-hour off-campus work rule permanent. This means you can now legally work up to 24 hours per week while classes are in session. This is an increase from the previous 20-hour limit and gives you more flexibility and income.
You can still work unlimited hours during scheduled academic breaks (like summer and winter holidays). Just be sure to maintain your full-time student status and have a valid SIN.
