Here’s what you need to know to stay up-to-date with us

Keep track of your transactions

Our online service for account and claim statements service gives you accurate and timely details on your WSIB account transactions. View and download your statements, including an archive of up to 18 months.


A clearance is a unique number issued by the WSIB that shows that a business, contractor or subcontractor is registered and up to date with us, including keeping current with premium payment and reporting. You can get and manage clearances online. Most newly registered employers requiring a clearance certificate at the time of registration will need to make an initial advance payment of $250. This payment is applied to your WSIB account as a credit and will be applied towards your future premiums.

If a workplace injury or illness happens

Each day across Ontario, people work in offices, construction sites, factories, warehouses and farms safely. But when a workplace accident happens, we are here to help.

As an Ontario business, you must pay your employee for the full day on the day of the incident and submit an Employer's Report of Injury/Disease form 7 online within three days of being notified of their injury or illness, if your employee:

  • needs more than first aid
  • is absent from work,
  • earns less than regular pay, or
  • requires modified work for more than seven days

If a fatal or catastrophic workplace accident occurs, call us at 1-800-387-0750. See injury or illness reporting for details and check our self-evaluator tool help you:
