Are general contractors in Ottawa licensed?
Ontario has no provincial licence for renovation contractors. The HCRA licenses builders of new homes, and a renovation of an existing home typically does not call for an HCRA licence.

Ask who does each part and check their numbers. Of the top 30 general contractors in Ottawa by ProScore, 7 are registered with WSIB according to ProScore’s records.
