Our WSIB Services Include

Who Needs to Register with WSIB?

Most Ontario businesses that employ workers — including full-time, part-time, casual, and seasonal employees — are required to register with WSIB within 10 days of hiring their first employee. Some industries and self-employed individuals have different requirements.

Industries that must register include construction, manufacturing, retail, healthcare, transportation, and many others. Professional services firms (law, accounting, engineering) are generally optional but may choose to register.

WSIB Premium Rates

WSIB premium rates vary by industry and are applied to your insurable earnings (total payroll). Rates are reviewed annually. Our team ensures your premiums are calculated correctly based on your specific industry classification and payroll, preventing overpayment or underpayment.

WSIB Annual Return

Every registered WSIB account must file an annual reconciliation return by February 28 each year. This return reconciles your actual insurable earnings for the previous year against the estimated premiums you paid throughout the year. We prepare and file this return as part of our year-end services.

Frequently Asked Questions

Are all Ontario businesses required to have WSIB?

No — some industries and businesses are exempt or have optional coverage. Construction businesses and most industrial businesses are mandatory. Service businesses and professional corporations may be optional. We can advise you on your specific registration requirements.

What happens if I don't register with WSIB?

Failure to register when required can result in back premiums, penalties, and interest. WSIB can also assess your account based on industry averages, which may result in higher premiums than if you had registered properly.

Do I need WSIB if I only hire subcontractors?

It depends on whether your subcontractors are considered independent operators under WSIB rules. We can help you assess whether your subcontractors require WSIB coverage and obtain clearance certificates.

Can you help if I have received a WSIB audit notice?

Yes — we provide full WSIB audit support, including reviewing your records, responding to WSIB inquiries, and representing your business throughout the audit process.
