Tarion Warranty Explained: What Every Ontario Pre-Construction Buyer Must Know

Buying pre-construction in Ontario means your purchase is backed by Tarion—the province's mandatory new home warranty program. Understanding how Tarion works can give you confidence and help you enforce your rights. Here's a comprehensive overview.

Deposit Protection

Tarion protects your deposits (up to $20,000 per unit) if the vendor goes bankrupt or fails to fulfill the contract. This is crucial when you're paying deposits over many months before a shovel hits the ground. The Tarion deposit protection page explains the conditions and limits.

Construction Defects and Warranty Periods

After closing, Tarion covers defects in workmanship and materials. The warranty has different periods: one year for cosmetic and minor issues, two years for major systems (e.g., plumbing, electrical), and seven years for structural defects. Full details are on the Tarion warranty coverage page. Ontario's official program page provides additional context.

Delayed Occupancy Compensation

If your unit isn't ready by the firm occupancy date, you may be entitled to compensation for living expenses. Tarion sets out the rules for when and how much. Tarion's delayed closing page has the specifics.

The Pre-Delivery Inspection (PDI)

Before closing, you'll complete a Pre-Delivery Inspection to document any deficiencies. This is your chance to create a formal record. Tarion's PDI guide explains the process and how to report issues. CBC and CTV have reported on common PDI issues and how to protect yourself.

Always Verify Registration

Before signing, confirm your developer is Tarion-registered. Unregistered builders leave you without warranty protection. For vetted pre-construction projects in the GTA, see our listings or contact us for guidance.
