Filing a Tarion claim without engineering documentation is how valid deficiencies get denied. We document defects to the Ontario Building Code, manage the claim strategy, and stand behind our reports at conciliation and the Licence Appeal Tribunal. Serving homeowners and condominium corporations across Toronto, Mississauga, Brampton, Vaughan, Markham, Oakville, Pickering, Oshawa and all of the GTA.
Tarion’s pre-approved and preferred engineering consultant for six consecutive years — trusted on both sides of the process to be independent and evidence-based.
Common-element warranty claims from the first-year performance audit through the builder's 18-month repair period and beyond.
Individual warranty claims done right the first time — before deadlines pass and evidence disappears.
Most warranty claims are won or lost on documentation, not argument. Here is how Ontario's process actually works, and where an independent engineer changes the result.
Submitting a warranty form starts a 120-day period for the builder to repair or resolve the items on your form.
If the builder doesn't resolve a warranted item, you can request a conciliation. Tarion charges a fee — $250 + HST for an individual homeowner's unit, or $1,130 ($1,000 + HST) for a condominium corporation's common-element claim — refunded if any assessed item is found to be covered. A Tarion Warranty Services Representative attends the property with the builder and assesses each item as an impartial decision-maker.
Tarion issues a report stating which items are warranted. The builder then has a final 30 days to resolve them — for common elements, Tarion follows up with the corporation 90 days after the report date.
If you disagree with Tarion's assessment, you can request a Decision Letter, ask Tarion to arrange independent mediation, and ultimately appeal to the Licence Appeal Tribunal (LAT).

Conciliation is Tarion's assessment process: a Warranty Services Representative inspects the items on your warranty form — usually at the property, with your builder present — and decides whether each is covered under the Ontario New Home Warranties Plan Act. Request one when the builder has not resolved a warranted item within the 120-day builder repair period. Timelines are strict and depend on your warranty start date, so check your dates early.
No — and the two are easy to confuse because they share a name. A Field Review Consultant (FRC) is a firm authorized by Tarion under Registrar Bulletin 19 to carry out quality reviews during construction of higher-risk condominium projects, engaged by the builder. The conciliation field review inspection described on this page is Tarion’s own site attendance after a warranty claim has been made, to assess disputed items. HexoTech does not currently hold Bulletin 19 Qualification Status and does not offer RB19 field review services. What we provide is independent engineering evidence for condominium corporations and homeowners bringing claims — on the other side of that process.
The Tarion representative asks questions, makes observations, takes photographs and may bring in a specialist. You are responsible for presenting your position and supporting documents. This is where an engineering report, testing evidence and code references carry the most weight — and where we attend alongside you.
Yes — after a Conciliation Assessment Report you can ask Tarion to arrange mediation with an independent external mediator, in most cases at Tarion's cost. That mediation is between you and Tarion. HexoTech is not a mediator: we are the engineers who prepare the independent technical evidence you bring into mediation, or into a Licence Appeal Tribunal appeal.
If Tarion finds the builder did not meet their warranty obligations during the repair period, the conciliation is deemed "chargeable": the builder pays Tarion's inspection fee and the result is recorded on their Ontario Builder Directory record for 10 years. This is why well-documented claims often get resolved before conciliation — and why builders take engineering evidence seriously.
New Ontario homes and condominiums carry warranties over one year (workmanship and materials), two years (water penetration, major systems) and seven years (major structural defects). Common elements of condominiums have parallel coverage that begins at registration.
It isn't mandatory — but valid deficiencies are routinely denied because the documentation doesn't tie the defect to the Ontario Building Code or the correct warranty category. As Tarion's pre-approved consultant, we know exactly what evidence gets deficiencies acknowledged and repaired.
A defect in work or materials that affects a load-bearing element of the building and materially compromises its structural integrity — covered for seven years. MSD claims almost always require an engineering investigation to succeed.
Yes. We prepare expert reports for Tarion conciliation and Licence Appeal Tribunal (LAT) proceedings, review builder repair proposals, and provide expert testimony where needed. We work alongside your legal counsel.
Both. We represent individual homeowners on 30-day, year-one, year-two and seven-year MSD claims, and condominium corporations on common-element claims following the performance audit.
