The WSIB is another complete jungle to get through when the employment status isn't quite clear.
They ask questions to determine the premiums or if you are required to pay for the insurance.
If you are sort of an employee and sort of a sole proprietor, you can't answer the questions properly.
As a result a lot of contractors don't register with the WSIB and then they get caught working without a certificate.
Fines for working without a clearance certificate are very high........up to $100,000.
