Does Tarion cover a Toronto renovation?

Tarion does not cover most Toronto renovations — it's specifically designed to protect buyers of newly built homes, not renovation projects.

Tarion Warranty Corporation is Ontario's new home warranty program, mandated under the Ontario New Home Warranties Plan Act. It covers new homes and condos built by registered builders, protecting buyers against defects in work and materials, delayed closings, and deposit loss. If you're buying a newly built home or condo in Toronto, Tarion is very relevant. But if you're hiring a contractor to renovate your existing home, Tarion doesn't apply to that work.

This is a common misconception, and it matters because some homeowners assume they have a safety net that simply isn't there. For renovation work — whether it's a kitchen remodel, basement finishing, addition, or bathroom upgrade — your protection comes from the contract you sign with your contractor, not from any government-backed warranty program.

So What Protection Do You Have for Renovations?

Your main protections as a Toronto homeowner hiring a renovation contractor are:

• A written contract outlining scope, materials, payment schedule, and warranty terms
• The contractor's own workmanship warranty (typically 1-2 years for most trades, though this varies)
• Ontario's Consumer Protection Act, which gives you some recourse against unfair practices
• WSIB coverage — ensure your contractor has a valid WSIB clearance certificate so you're not liable if a worker is injured on your property
• Liability insurance — your contractor should carry a minimum of $2 million in general liability

Ontario Building Code inspections also provide a layer of protection — when permits are pulled and work is inspected, it ensures the work meets minimum code standards. This is one of the strongest reasons to always insist on proper permits for your renovation.

One Exception Worth Knowing

If your renovation involves converting your home into a new unit — such as building a laneway suite or garden suite from the ground up — and a builder is constructing it as a new dwelling, Tarion registration may be required depending on the structure. This is a nuanced area worth clarifying with your builder.

Your next step is to ensure any renovation contractor you hire provides a detailed written contract, proof of WSIB clearance, and valid liability insurance before work begins. You can find vetted local contractors through the Toronto Construction Network directory — a great starting point for comparing Toronto-area trades for your project.
