Getting Started - Construction

Welcome to the WSIB registration site. To make registering with us as easy as possible, we will guide you through a series of simple questions to get you started.


Wondering if you need to register?

If you run a construction business, you need to register with the WSIB. Effective January 1, 2013, independent operators*, sole proprietors, executive officers of corporations, and partners in partnerships are considered workers and require coverage with the WSIB. In addition, other workers include family members, occasional workers, and workers covered by their principal contractor. You need to register within 10 days of hiring your first worker.


*Independent Operator in construction means an individual who does not employ any workers, reports himself or herself as self-employed for the purposes of an Act or regulation of Ontario, Canada or another province or territory of Canada (e.g., Canada Revenue Agency), and is retained as a contractor or subcontractor by more than one person during an eighteen (18) month period or, an individual who is an executive officer of a corporation that, does not employ any workers other than the individual, and is retained as a contractor or subcontractor by more than one person during an eighteen (18) month period.


Here's a list of the information you'll need to have on hand when you register (some may not apply):

  • Business legal name
  • Business trade name
  • Canada Revenue Agency (CRA) Business Number (if available)
  • Information about ownership (sole proprietor, partners in the partnership, executive officer(s) of the corporation), including name, address, date of birth.
  • Business addresses, phone number, fax number
  • Start date of the worker(s) you hired
  • An estimate of gross insurable earnings for a full calendar year
  • Email address

I am authorized to submit this registration on behalf of the legal entity (employer) named in this registration. I acknowledge that the information submitted in this registration is accurate and complete to the best of my knowledge and will be used to establish an account.
