How do I verify that a bathroom renovation contractor in Ontario is registered with HCRA?

HCRA (Home Construction Regulatory Authority) registration applies specifically to builders and vendors of new homes in Ontario — not to renovation contractors working on existing homes. This is one of the most common points of confusion among GTA homeowners planning bathroom renovations, and understanding the distinction is important for verifying your contractor's credentials properly.

The HCRA replaced the former Tarion registration system for builder licensing in February 2021. It licenses and regulates businesses that build or sell new homes in Ontario, ensuring they meet competency and financial requirements. If you are buying a newly built home and want to verify that the builder is properly licensed, you can search the HCRA's public registry at hcraontario.ca. Similarly, Tarion warranty coverage applies to defects in new home construction — covering materials and workmanship for up to 7 years on new builds — but does not cover renovations to existing homes.

What to Verify for a Renovation Contractor

Since HCRA registration does not apply to bathroom renovation contractors, here is what you should verify before hiring a contractor for your GTA bathroom project:

WSIB (Workplace Safety and Insurance Board) coverage. Request a current WSIB clearance certificate from your contractor. This confirms they carry workplace injury insurance for their employees. If an uninsured worker is injured on your property, you could face liability. You can verify WSIB coverage online at wsib.ca using the contractor's business name or account number. This is one of the most important checks you can do.

Liability insurance. Your contractor should carry a minimum of $2 million in commercial general liability insurance. Ask for a certificate of insurance naming you or your property. This protects you if the contractor causes damage to your home — a burst pipe during rough-in, water damage from a plumbing error, or accidental damage to finishes.

Licensed trades. In Ontario, plumbing and electrical work must be performed by licensed tradespeople. Ask your contractor to confirm that their plumber holds a valid Ontario plumbing licence (or Certificate of Qualification from the Ontario College of Trades / Skilled Trades Ontario) and that their electrician is licensed with the Electrical Safety Authority (ESA). You can verify an electrician's licence through the ESA at esasafe.com.

Business registration. Verify that the contractor operates as a registered business in Ontario. You can search the Ontario Business Registry for their corporation or business name. A legitimate contractor will have a registered business name, HST number, and proper business structure.

Additional Due Diligence

References and past work. Ask for 3 to 5 references from recent bathroom renovation projects in the GTA, and actually call them. Ask about timeline adherence, communication, quality of finishing work, and how the contractor handled any issues that arose. If possible, visit a completed project in person.

Written contract. Ontario's Consumer Protection Act requires home renovation contracts over $50 to be in writing. Your contract should include a detailed scope of work, itemized pricing or clear allowances, payment schedule tied to milestones (never pay more than 10 to 15% upfront as a deposit), start and estimated completion dates, warranty terms, and a dispute resolution process.

Permit history. Ask whether the contractor regularly pulls permits for their projects. A contractor who avoids permits is a red flag — permits protect you by ensuring work is inspected for Ontario Building Code compliance. You can verify open and closed permits through the City of Toronto's online permit records.

Lien history. Construction liens filed against a contractor can indicate payment disputes with subcontractors or suppliers. While this requires a title search, it is worth checking for larger projects.

The bottom line: while HCRA registration is not the right credential to check for a renovation contractor, there are several meaningful verifications — WSIB, insurance, trade licences, and references — that will help you hire a qualified bathroom renovation professional in the GTA.
