By law, most businesses need to register with the WSIB within 10 calendar days of hiring their first employee. If you own or operate a business in construction, your registration obligation may be different. You can learn more about mandatory coverage in the construction industry.

If you’re not registered with us, and should be, you can voluntarily register your business for the first time. To register your business, please gather your business information, sign up for our online services and then use the registration service.

Signing up for our online services does not mean you have registered your business. After creating an online services account, you must use the registration service to complete your registration. 

Not registering may result in penalties, investigation and provincial offences charge or having to repay retroactive premiums. See our policy on voluntary registration to learn more.

No. We ask that you register with us 10 calendar days of hiring your first employee. We don’t accept future-dated registrations.

If you own or operate a business in construction, you can register as of the date your business starts performing construction work, or the date you meet the criteria of an independent operator in construction, see our policy on Workers and Independent Operators for more information. You can also learn more about mandatory coverage in construction.

Businesses have an obligation to find out if they should register in Ontario when either hiring:

• Ontario resident employees to work in Ontario, or
• Employees from outside of Ontario to work in Ontario

Most non-resident businesses who employ an Ontario resident to work in Ontario are required to have coverage for them with the WSIB. A non-resident employee is someone whose permanent residence is outside of Ontario. A non-resident employee who works in Ontario normally has a substantial connection with Ontario unless the employment here is minimal and short-term, compared to their employment somewhere else. See our policy on non-resident workers for more information about your registration obligations.

Registering is free, but if you need a clearance certificate right away and haven’t paid any premiums, you’ll need to pay a $250 deposit to get the clearance certificate. The $250 will act as a credit on your account, so when the time comes for you to pay your premiums, you’ll have already paid $250 against the bill. You can get your clearance certificate online quickly and easily.
