What happens if my builder is registered with Tarion but the actual construction company is different?

The Home Construction Regulatory Authority (HCRA) licenses builders and vendors — the entities that sell new homes to consumers — while Tarion administers the warranty itself. Under the Ontario New Home Warranties Plan Act, it is the vendor and/or builder who has the statutory obligation to provide the warranty. Separately, the New Home Construction Licensing Act, 2017 requires that vendor or builder to be licensed by the Home Construction Regulatory Authority (HCRA) — HCRA licenses, Tarion warranties. The warranty obligation runs to the purchaser from the registered entity.

In practice, larger development projects often involve a layered corporate structure: a vendor entity (the company that signs the purchase agreement with buyers) and a construction company or general contractor that actually builds the home. These may be separate legal entities. What matters for your warranty coverage is whether the vendor — the party you contracted with — is the licensed vendor on the enrolment.

The construction entity that physically builds the home does not independently need its own licence, but the vendor/builder relationship must be properly constituted. Tarion's registration system captures these structures.

If you have questions about who exactly is warranting your home, check the Tarion warranty certificate you receive after possession. It identifies the registered vendor and the home. Any claim must be made against the registered vendor through Tarion's system. If the corporate structure is unusually complex or confusing, your real estate lawyer can help clarify who bears the warranty obligation.
