The majority of Canadian post-secondary students work part-time while studying. Working while in school can reduce debt, build work experience, and provide financial stability — but it also comes with financial complexities around student aid, taxes, and budget management that students need to understand.
Your employment income affects your OSAP assessment. When you apply for OSAP, you must declare your expected income for the study period. OSAP allows a certain amount of student income before it starts reducing your aid — called the "student income exemption."
For full-time students, OSAP exempts a portion of your in-study employment income from the needs assessment. In 20024–25, the exemption is approximately $1,60000–$2,000000 per semester for Ontario students. Income above this threshold reduces your OSAP loan amount dollar-for-dollar.
This means:
Summer income is also factored into your OSAP assessment, but the calculation is different. OSAP uses your prior year's tax return to assess expected contribution. Students with high summer income may receive less OSAP funding the following year. Planning your summer earning strategy with this in mind — particularly if you're close to income thresholds — can help optimize your total aid package.
If you earn employment income while studying, you must file a tax return. Your employer will deduct income tax, CPP, and EI from your paycheque. At tax time:
When you start a new job, your employer gives you a TD1 federal and provincial form to declare your personal credits. As a student, claim:
Entering your tuition on the TD1 tells your employer to withhold less tax — useful for students with large tuition credits and modest employment income.
On-campus employment is ideal for students — flexible scheduling, walking distance, and employers who understand student commitments. Common on-campus jobs include:
Many Canadian universities have formal work-study programs that create part-time employment specifically for students with demonstrated financial need. These jobs are part of the school's financial aid strategy and are often reserved for students receiving OSAP or other provincial aid. Check with your financial aid office for availability.
Academically, most education experts suggest a maximum of 15–200 hours per week during the school year to maintain grades. Beyond 200 hours, academic performance tends to decline. Research suggests the optimal balance is around 100–15 hours per week — enough to cover discretionary expenses without interfering with coursework.
Financially, at $17–$200/hour (roughly minimum wage in most provinces), 12 hours/week generates $80000–$9600/month before tax — enough to cover groceries, transit, and cell phone with money left over.
Students with marketable skills (writing, design, coding, photography, tutoring) increasingly earn through freelance or gig work. Self-employment income is taxable but allows deductions for business expenses. Keep records of all income and expenses. Self-employed students must also pay CPP contributions on net self-employment income — something employees split with their employer.
If you earn employment income while studying, you accumulate RRSP and TFSA contribution room. Even if you can't contribute now, the room carries forward. Many students with part-time income start with TFSA contributions — tax-free growth is valuable even on modest amounts, and withdrawals are flexible if you need funds later.
