In Ontario, international students working with a valid IRCC work permit or off-campus work authorization are fully covered under the Workplace Safety and Insurance Act. Employers are legally required to report their earnings to the WSIB and pay the corresponding industry premiums, just as they do for Canadian citizens.
Ontario is home to world-class educational institutions in cities like Waterloo, London, Toronto, and Ottawa, attracting hundreds of thousands of international students every year. To afford the high cost of living, many of these students take on part-time jobs in restaurants, retail, warehouses, and the gig economy. A common misconception among small business owners is that foreign students, temporary foreign workers, or individuals without permanent residency are somehow exempt from provincial labour laws or the workers’ compensation system.
This is a dangerous and costly myth. 📍 The Workplace Safety and Insurance Board (WSIB) provides no-fault insurance based on the nature of the employment relationship, not the worker’s citizenship or immigration status. By May 2026, the rules are crystal clear: if an international student is working for your business, they are classified as an employee under the Workplace Safety and Insurance Act (WSIA). Failing to declare their wages and pay premiums is considered premium evasion, which can lead to severe audits, massive fines, and retroactive billing. Here is how you can ensure your business remains legally compliant.
Step-by-Step Process for Registering International Student Workers in Ontario
Hiring international students is an excellent way to fill labour shortages, but it requires diligent payroll management. Integrating foreign students into your WSIB reporting structure is a straightforward process if you follow these precise administrative steps.
Step 1: Verify Work Authorization and SIN
Before putting a student on the schedule, you must verify that they are legally allowed to work in Canada. 🔍 Check their study permit to ensure it includes conditions allowing off-campus work (adhering to current IRCC hour limits). Obtain their Social Insurance Number (SIN); international students are usually issued a SIN starting with the number ‘9’. You must retain copies of these documents for your payroll records.
Step 2: Register Your Business with the WSIB
If this international student is your very first employee, you must formally register your business with the WSIB. Under Ontario law, most businesses must register within exactly 10 days of hiring their first worker. You can complete this registration easily through the WSIB online portal by providing your Canada Revenue Agency (CRA) business number and payroll details.
Step 3: Calculate Insurable Earnings
When it is time to report to the WSIB, you must calculate the “insurable earnings” for all your employees, including the international students. 💰 Insurable earnings generally include their gross hourly wages, vacation pay, tips (if controlled by the employer), and any room and board provided. You must combine the student’s wages with the wages of your Canadian employees to find your total payroll figure.
Step 4: Report and Remit WSIB Premiums
Depending on the size of your payroll, you will be required to report and pay your WSIB premiums on a monthly, quarterly, or annual basis. Log into your WSIB online services account, enter the total insurable earnings, and the system will automatically multiply that amount by your specific industry premium rate. Pay the balance promptly to avoid interest charges.
Step 5: Provide Workplace Safety Training
Foreign students may not be familiar with Canadian workplace safety standards. 👥 You are legally required by the Occupational Health and Safety Act (OHSA) to provide basic safety training. Ensure they know exactly who to report an injury to, and clearly display the WSIB “In Case of Injury” (Form 82) poster in a prominent area, like the staff breakroom or kitchen.
Step 6: Consult an Employment Lawyer or Accountant
If you are ever audited by the WSIB and are accused of paying international students “under the table” or failing to declare their wages, it is crucial to speak with a professional. A local Ontario employment lawyer or a chartered accountant can help you navigate the audit, negotiate a payment plan for retroactive premiums, and shield your business from the harshest penalties.
How Much Does it Cost in Ontario?
The cost of WSIB coverage for an international student is identical to the cost for a Canadian worker. The exact amount you pay depends entirely on your industry classification rate.
| Feature | Estimated Cost (CAD) | Details |
|---|---|---|
| WSIB Registration Fee | $0 | Registering an account with the board is free for employers. |
| Premium Rate (e.g., Restaurants) | Approx. $0.80 per $100 | If a student earns $1,000, you pay $8.00 in premiums (rates vary by NAICS code). |
| Premium Evasion Fines | Up to $500,000 | Corporate fine for intentionally hiding payroll or paying students “under the table.” |
| Maximum Insurable Earnings | Over $116,000 annually | You only pay premiums up to the annual ceiling; part-time students rarely hit this cap. |
How Long Does the Process Take?
Maintaining compliance with WSIB reporting deadlines is a continuous, year-round administrative duty. ⌖ Missing deadlines will trigger automated administrative fines on your account.
- Initial Registration: Must be completed within exactly 10 days of hiring your first employee, regardless of their nationality.
- Premium Reporting: Typically due by the last day of the month following your assigned reporting period (monthly or quarterly).
- Clearance Certificates: WSIB clearance certificates, proving your account is in good standing, are generally valid for 90 days at a time.
- WSIB Audits: If flagged, an employer audit can investigate your payroll records from the past several years to uncover unpaid premiums.
Frequently Asked Questions (FAQ)
What happens if the student gets injured and returns to their home country?
If the injury was work-related, the student is still entitled to WSIB benefits. However, managing healthcare and loss of earnings internationally is highly complex, and the board will require constant medical updates from foreign doctors to continue payments.
Are international students eligible for loss-of-earnings benefits?
Yes. If an injury prevents them from performing their part-time job, they are entitled to 85% of their net average earnings, just like any other worker, provided they have a valid work permit.
Do I have to pay WSIB if I pay the student in cash?
Yes. Paying an employee “under the table” in cash to avoid taxes or WSIB premiums is strictly illegal. All compensation, regardless of how it is distributed, must be declared as insurable earnings.
What if the student exceeds their IRCC permitted work hours?
While exceeding the allowed hours violates federal immigration law, the WSIB still considers them an employee under provincial law. You must report all wages paid, and the student will still be covered if injured, though they may face separate IRCC consequences.
Do I deduct the WSIB premium from the student’s paycheck?
Absolutely not. Under the WSIA, employers are strictly forbidden from deducting WSIB premium costs from a worker’s wages. The employer must bear 100% of the insurance cost.
