An independent operator/contractor must have to have mandatory coverage with WSIB; however, in case of an accident WSIB can decide your company is responsible for the individual and deem him or her your employee. To minimize your exposure to WSIB costs/penalties confirm with WSIB the status of the independent operator before you hire them, by having you and the independent operator complete a WSIB questionnaire form, both signing it and sending it to WSIB for a decision.
The WSIB FAQ Employee (worker)/independent operator status provides more details. Visit also the Office of the Employer Adviser site for more information and read WSIB policy concerning Workers and independent operators.
There is mandatory registration for owners of a business in the construction industry.
