Tarion Warranty and New Home Protection — What Every Markham New Build Buyer Must Know
Every new home in Ontario comes with Tarion warranty coverage — but most Markham pre-construction buyers understand it only vaguely, and that gap costs money. Michael John Lau & Neeraj Moolchandani explain the coverage periods, the new 2026 registration deadline, and deposit protection.
Every new home built in Ontario — from a $452,900 boutique condo on Main Street Markham to a $2,200,000 Cornell Rouge detached home — comes with one of the most important consumer protection programs in Canadian real estate: the Tarion new home warranty. But most Markham buyers who sign pre-construction purchase agreements understand Tarion in only the vaguest terms — and that gap in understanding costs them money, time, and stress.
Michael John Lau and Neeraj Moolchandani, top real estate agents in Markham Ontario, make Tarion literacy part of every new construction buyer conversation. Here is everything you need to know before you sign.
What Tarion Is — and What It Is Not
Tarion administers Ontario’s new home warranty program. Your warranty coverage starts around the purchase process and continues for up to 7 years after possession depending on the issue category. The warranty stays with the home if it is sold. Coverage is provided by builders and backstopped by Tarion.
What Tarion is not: a general “everything that annoys me must be fixed” program. New homes settle. Materials move. Wood shrinks. Concrete cures. Some of that is normal; some is not. The warranty protects you from defects that fall within defined coverage — not a guarantee your home stays showroom-perfect through four seasons of Ontario humidity. Understanding this distinction before possession is essential.
The Three Coverage Periods — What Is Covered and When
Year One — Workmanship and Materials
The one-year coverage begins on possession and covers defects in work and material, unauthorized substitutions, violations of the Ontario Building Code, and fitness for habitation. This is your broadest coverage window — use it. Document everything you notice within the first 30 days on your 30-Day Form, and again at your year-end on the Year-End Form.
Year Two — Building Envelope and Major Systems
The two-year coverage begins on possession and covers defects in the electrical, plumbing, and heating delivery and distribution systems, water penetration through the building envelope, and Code violations affecting health and safety. Water penetration is the critical two-year item — if your Markham new build develops a leak through the roof, windows, cladding, or foundation in the first two years, document it thoroughly and file before the two-year anniversary.
Years Three to Seven — Major Structural Defects
The seven-year major structural defect warranty covers serious structural failures such as foundation problems or collapsed load-bearing elements. For Markham buyers in Cornell Rouge, Gallery Towers, UnionCity, and the broader pipeline, this provides the long-term backstop that makes new construction’s risk profile manageable.
The Critical New 2026 Deadline: Effective January 1, 2026, new freehold homebuyers must notify Tarion of their purchase and provide transaction particulars within 45 days of signing their Agreement of Purchase and Sale. The 45-day window starts from your APS signing date — not possession, which may be years away. Buyers who miss this deadline may have reduced compensation in cases of builder bankruptcy or cancellation.
Deposit Protection — The Most Important Pre-Possession Protection
Tarion provides deposit protection if a builder fails to complete a project due to bankruptcy or abandonment. For new-build homes, the maximum financial limit for certain defects in work and materials is $400,000. For new condominium units, the maximum financial limit is $300,000.
For Markham pre-construction buyers paying staged deposits on projects that may not complete for two to three years — Gallery Towers, UnionCity, Pangea Condos, Cornell Rouge — deposit protection is the most immediately relevant Tarion benefit. Register your purchase within 45 days of signing, keep all deposit receipts and correspondence, and understand that your deposits are protected against builder insolvency up to the applicable limits.
Buy New Construction With Confidence
Michael John Lau & Neeraj Moolchandani research builder Tarion history before recommending any project, and guide you through registration, PDI, and warranty timelines — at no cost to you on most new builds.

The PDI — Pre-Delivery Inspection — is the walkthrough of your completed new home before you take possession. It is your opportunity to identify and document every defect, missing item, damage, and departure from specifications before the keys change hands. Both scratched hardwood floors and sticky windows should be flagged. Reporting within 30 days ensures the builder addresses them promptly.
Attend the PDI with a notepad, a camera, and a checklist. Do not be rushed. Document everything in writing and photograph everything you flag. The PDI form you sign becomes the baseline record for your 30-Day Form claims — if it is not on the PDI form, the builder may argue it existed before possession.
Checking Your Builder’s Tarion History
Before signing any Markham pre-construction agreement, verify your builder’s registration and complaint history on Tarion’s public registry at tarion.com. The searchable database includes registration status and any warranty conciliations, Director’s Orders, or chargeable conciliations on record. A clean Tarion history is not a guarantee of quality — but a history of unresolved warranty complaints is a material red flag.
Michael John Lau and Neeraj Moolchandani, top real estate agents in Markham Ontario, research builder Tarion history as standard practice before recommending any new construction project to buyer clients. This is the level of due diligence that distinguishes experienced new construction representation from simply walking clients into a sales office.
