Coverage and premiums

Most businesses in Ontario that employ workers must register with the WSIB within 10 days of hiring their first full or part-time worker. Although this is a legislative requirement, there are many benefits to you, as the employer. Find out about the registration process and the premium rate you can expect to pay.

We sometimes audit employers to ensure accurate payroll reporting and proper rate group classification. Find out more about this process by visiting our Employer audits page.

If you disagree with a decision we’ve made, we offer a variety of resolution processes.
