ProScore profiles are built from publicly available information and official public registries, and scored using ProScore’s own methodology. We check this data against third-party sources and work to keep it accurate, but records change and errors can occur. A ProScore is informational only — it is not a guarantee, endorsement, or recommendation. Before hiring any contractor, you should independently verify and confirm all relevant credentials, licences, insurance (including WSIB coverage) and references directly with the contractor and the issuing authority.
