Before your first job we need the licence or certificate your trade requires, proof of liability insurance and, where WSIB coverage applies to your work, a current clearance. We check each against the issuer where we can, and check the clearance before booking and before every payment, and the insurance before every payment.

WSIB clearance, where WSIB coverage applies to your work. It shows your business is registered and up to date with WSIB. It lasts up to 90 days, and a payment waits until a current one is on file.
Liability insurance. You carry commercial general liability insurance to apply, with Roundhouse named as an additional insured. We confirm the limit with you when you apply.

In Toronto, also a City of Toronto Plumbing Contractor licence; elsewhere, the licence the city requires. Toronto requires it of any business contracting or repairing plumbing, or advertising as a plumbing contractor. |

Yes. TSSA says that when a contractor agrees to do work and subcontracts it to another contractor, both have to meet the registration and certification requirements.
Independent operators outside construction may not have to register with WSIB, and a business that is not registered cannot get a clearance. Tell us when you apply and we will say what to send instead.
Up to 90 days. We check it before booking and before every payment, so send the new one when it is issued.
