Registration FAQs

Getting started

How do I know if I need to register my business?

We have a few questions to help you figure it out.

What happens if I register my business more than 10 calendar days after hiring my first employee?

Businesses in most industries are required by law 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 differ. You can learn more about mandatory coverage in the construction industry.

If you are not registered with the WSIB, and should be, you can voluntarily step forward and register your business for the first time in which case we may waive penalties, refrain from investigating and/or laying provincial charges, and only require payment of retroactive premiums (interest free) up to 12 months from the effective date of registration. See our policy on voluntary registration.

If you do not step forward and register your business and your business is identified through an investigative processes, such as the WSIB’s information exchange agreement with the Canada Revenue Agency (CRA), discovery through a business audit, registration initiated by an injury/illness to an employee, or any other circumstances where you did not step forward to register voluntarily, you may be subject to a financial penalty and/or legal charges.

We cover all employees that work for a business that must be registered with us – even if that business hasn’t registered. 

What do I need to know if I run a business that’s not based in Ontario but hires people to work in Ontario?

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.

How do I register if I had a WSIB account in the past?

Use our online registration service to register. You’ll be able to include any prior and/or existing account(s) you’ve had with the WSIB. We will review the information and decide if a new account will be created, or if your prior account will be reactivated. If we have any questions, we’ll contact you.

How do I register a new account, if I already have an account with the WSIB?

Use our online registration service to register. You’ll be able to include any prior and/or existing account(s) you’ve had with the WSIB. We will review the information and decide if a new account will be created based on the legal name and physical location of business. If we have any questions, we will contact you.

Do I have to sign up for the eRegistration service, and is there a cost?

eRegistration is a free service, and does not require sign up. Visit eRegistration to register now.

What if I don’t want to register online?

We encourage you to register online but you are able to register by phone, in person, by mail or fax. Contact us to find out more.

Registering online

Is the online registration service available to anyone registering for an account?

Yes, anyone can use our online service to submit business registration details if they have hired an employee or they operate their business alone as a contractor.

Can my representative (e.g. accountant/bookkeeper, family member, etc.) register my business for me?

Yes, but they must check off the statement saying that they are authorized by the business owner to submit registration information.

Can I register my new business prior to hiring employees?

No. The Workplace Safety & Insurance Act asks that you contact us within 10 calendar days of hiring your first employee. We do not 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.

Can I save information I enter in the online eRegistration system and return to it later?

No. For security reasons, you must enter all information and submit it at one time. You will be timed out of your session if you are inactive for 30 minutes, and none of the information you have entered will be saved or stored online. To avoid this, please navigate to another page before 30 minutes has elapsed.

We recommend havingall necessary information on hand before you start.

How do I know when my registration is complete?

Once you have submitted your information to us online, a confirmation number will be displayed on a printable summary page. We will also email this number to your company contact email address you provided to us during registration. Once your account has been activated, we’ll email you your WSIB account number and send you a welcome package by mail.

How long will it take to get my WSIB account activated after I submit my information online?

If we have all the information that we need from you, your account will typically be activated within 10 business days.

I did not receive a confirmation email after submitting my registration information. What happened?

The confirmation email is sent to the company contact email address that you provided.

You will not receive the email if the email address provided was invalid, incomplete, or filtered to exclude email from unknown senders. However, if you clicked on 'submit' and a confirmation number was displayed onscreen, then we do have your registration information and will contact you with your account information.

We’ll then provide a confirmation number you and we’ll send an email to confirm the receipt of your registration application.

I submitted registration information online and got a confirmation number by email. Does this mean I now have a WSIB account?

Not yet. The confirmation email confirms the receipt of your registration information. We will review the information you submitted and we’ll email you your WSIB account number and send you a welcome package by mail.

I submitted eRegistration information and found I made a mistake, how can I go back to my submission to revise it?

You cannot revise an eRegistration submission once you've created it and received your confirmation number. Have your eRegistration confirmation number ready and call 416.344.1000 or 1.800.387.0750 for assistance.
