What's the HCRA, and does my bathroom contractor need to be registered with them?

The HCRA — Home Construction Regulatory Authority — is Ontario's regulatory body that licenses builders and vendors of new homes, and your bathroom renovation contractor does not need to be registered with the HCRA unless they are building or selling brand-new homes. This is a common point of confusion for Toronto homeowners, so it is worth understanding clearly.

The HCRA was established in 2021 as an administrative authority under the Ontario New Home Warranties Plan Act. Its primary role is to license and regulate new home builders and vendors — companies that construct and sell new residential properties in Ontario. If a company is building a new house, new townhome, or new condo building, they must be licensed by the HCRA. The HCRA replaced the previous licensing function that was handled by Tarion.

HCRA and Renovation Contractors

Renovation contractors — including bathroom renovation specialists working across the GTA — are not required to be HCRA-licensed because they are renovating existing homes, not building new ones. There is currently no provincial licensing requirement for renovation contractors in Ontario, which is why due diligence falls heavily on the homeowner.

This does not mean your bathroom contractor operates in a regulatory vacuum. Ontario has other protections and requirements that apply to renovation work:

WSIB (Workplace Safety and Insurance Board) coverage is essential. If an uninsured worker is injured on your property during a bathroom renovation, you as the homeowner could be held liable. Always request a WSIB clearance certificate from your contractor before work begins. Legitimate GTA bathroom contractors carry WSIB coverage as standard practice.

Licensed trades are required for specific work. Plumbing work must be performed by or under the supervision of a licensed plumber (holding a Certificate of Qualification from the Ontario College of Trades or its successor). Electrical work must be performed by a licensed electrician, and all electrical installations require an ESA inspection. These trade licensing requirements protect you regardless of whether the general contractor holds any other certification.

Liability insurance is another must-have. Your bathroom contractor should carry a minimum of $2 million in commercial general liability insurance. This protects you if the renovation causes damage to your property — for example, a plumbing connection failure that causes water damage to floors below.

Tarion Warranty and Bathrooms

Tarion provides warranty coverage for new home construction in Ontario, covering defects in materials and workmanship for up to 7 years on certain components. If you purchased a newly built home in the GTA and discover bathroom defects within the warranty period, Tarion coverage may apply. However, Tarion does not cover renovation work on existing homes. If you are renovating the bathroom in your 1960s North York bungalow or your 2005 Mississauga townhouse, Tarion warranty does not apply to the renovation — your protection comes from your contract with the renovation contractor and their liability insurance.

What to Check Instead

Since HCRA registration does not apply to bathroom renovators, here is what you should verify before hiring a bathroom contractor in the GTA: WSIB clearance certificate (current and valid), commercial general liability insurance ($2 million minimum), references from recent GTA bathroom projects (ask for 3–5 and actually call them), confirmation that they use licensed plumbers and electricians for those portions of the work, and a detailed written contract specifying scope, materials, timeline, payment schedule, and warranty terms.
