Research brief: Tarion Warranty Corporation — definitive reference (May 2026)

Status: Definitive Tarion reference compiled May 2026. Source brief for the 28 atomic Tarion entries that follow it. Peer to Research brief: Ontario Home Construction Regulatory Authority (HCRA) — definitive reference (May 2026).

Why this brief exists

Tarion is the second of the two regulatory bodies every Ontario new-home builder client deals with (HCRA is the first — see HCRA + Tarion are two distinct gates — an Ontario new-home builder needs both to legally build or sell). Buyers increasingly research Tarion coverage before signing, and the 2024 deposit-payout crisis ($100M+) plus the 2025/2026 enrolment-fee and deposit-rule changes have made Tarion a live topic.

TL;DR — 15 decision-ready facts

1. Tarion was established in 1976 under the Ontario New Home Warranties Plan Act (Tarion established 1976 under the Ontario New Home Warranties Plan Act; not-for-profit administrative authority, not a Crown agency).
2. On Feb 1, 2021, HCRA took over builder licensing; Tarion kept warranty admin, deposit protection, the Guarantee Fund, and dispute resolution (Post-Feb 2021 split: Tarion retained warranty administration, deposit protection, Guarantee Fund, conciliation; HCRA took licensing and conduct).
3. Statutory warranty is 1-2-7 — workmanship year 1, building envelope/distribution year 2, Major Structural Defects years 3-7 (Tarion 1-2-7 warranty in full — year-by-year coverage from possession through year 7 (workmanship, building envelope, distribution systems, MSD)).
4. MSD is defined by a three-test framework: failure, function, use (Major Structural Defect (MSD) — three-test framework (failure / function / use) defines what qualifies for year 3-7 coverage).
5. For APS signed on/after July 1, 2023: $400K freehold / $300K condo / $100K × units common-elements to a $3.5M cap, $50M project cap (Tarion coverage caps: APS on/after July 1, 2023 — $400K freehold / $300K condo unit / $100K × units common elements to $3.5M cap; $50M project cap).
6. Delayed closing: $7,500 cap, $150/day living expenses, $1,500 penalty if builder gives no 10-day notice (Tarion delayed closing / occupancy compensation — $7,500 cap, $150/day living expenses, $1,500 penalty for no 10-day notice).
7. Freehold deposit protection: $60K (≤$600K homes) / 10% to $100K (>$600K homes) (Tarion deposit protection — freehold: $60K (≤$600K homes) or 10% to $100K (>$600K); contract homes: $40K financial-loss coverage).
8. Condo deposits held in trust; $20K Tarion backup if trust fails (Condo deposit protection — held in trust under Condominium Act s.81; Tarion backs up $20K if trust fails).
9. April 1, 2026: freehold buyers must notify Tarion within 45 days of signing to qualify for full deposit coverage (coverage-tier changes deferred to Jan 1, 2027) (O. Reg. 17/25 freehold deposit change — from April 1, 2026, buyers must notify Tarion within 45 days of signing to qualify for full coverage; tier change deferred to Jan 1, 2027).
10. Conciliation is the adjudication step — if any item warranted, builder charged $1,000+HST per home ($3,000+HST common-elements) and the record stays on the OBD for 10 years (Tarion conciliation process — 120-day builder repair, $250 homeowner deposit, $1,000/$3,000 chargeable to builder if any item warranted, 10-year OBD record).
11. Homeowner appeals go to the Licence Appeal Tribunal within 30 days of a Decision Letter — note: HCRA matters get 15 days, Tarion gets 30 (Tarion LAT appeals — 30 calendar days from Decision Letter (vs HCRA's 15 days); first hearing ~37 days, decision ~40 days post-hearing).
12. 2025 enrolment fees (Bulletin 15, effective Sept 1, 2025): "$1,790 average payable by the vendor," 3.1% increase on $800K homes, with a $250 capital-replenishment surcharge (Tarion enrolment fees Sept 1, 2025 (Registrar Bulletin 15) — "$1,790 average payable by the vendor"; 3.1% increase on $800K homes; $250 capital-replenishment surcharge).
13. 2024 Guarantee Fund payouts exceeded $100M — largest single-year consumer payout in program history, driven by builder bankruptcies and >900 deposit claims (Tarion Guarantee Fund — 2024 payouts >$100M (largest single year in program history); 900+ deposit claims drove the $250 capital-replenishment surcharge).
14. The 2019 Auditor General Special Audit found ~9,700 homeowner requests dismissed for missed deadlines (1,300 by a single day), 65% of conciliations found the builder at fault, and the OHBA had "disproportionate influence" (Tarion 2019 Auditor General Special Audit (Bonnie Lysyk) — 65% of conciliations found builder at fault, 9,700 dismissed for missed deadlines (1,300 by 1 day), OHBA "disproportionate influence").
15. Tarion does not cover renovations — renovators rely on RenoMark + in-house workmanship warranties (Tarion coverage boundary — covers new homes, contract homes, RCCPs; does NOT cover renovations to existing homes or owner-built homes, RenoMark certification — CHBA private-sector renovation program; minimum 2-year written workmanship warranty, liability insurance, written contract, code of conduct).

What this brief recommends Candid do for builder clients

• Add a "Tarion-enrolled" acknowledgment to every new-home product/landing page.
• Surface deposit-protection limits in pre-construction marketing — these are now top-of-mind for buyers after 2024.
• Encourage clients to plan for the April 2026 / Jan 2027 freehold deposit-notice rule in their sales process.
• See RULE: Every Candid builder-client site must surface Tarion warranty coverage on every new-home product/landing page, with 1-2-7 structure named and CSS forms referenced for the canonical Candid rule.
• For PDI-related buyer education, see Pre-Delivery Inspection (PDI) — mandatory pre-possession walkthrough; PDI Form is not a warranty claim but failure to note items makes proof harder.

Honest caveats

• 2024 Guarantee Fund balance not fully extracted from the 2024 Annual Report; for context, the Fund stood at $592.3M in 2018 (Tarion Guarantee Fund — 2024 payouts >$100M (largest single year in program history); 900+ deposit claims drove the $250 capital-replenishment surcharge).
• Toronto Star investigative reporting on Tarion is led by Kenyon Wallace (not Robert Cribb, who is a Star investigative reporter focused on other beats) (Toronto Star Tarion investigation — multi-year reporting led by Kenyon Wallace (not Robert Cribb); CBC reporting led by Laura Osman).
• LAT self-rep success rate ("most SRLs lose") is from NSRLP/Captijn, not a published Tribunals Ontario stat — treat as [Reported] (Tarion LAT appeals — 30 calendar days from Decision Letter (vs HCRA's 15 days); first hearing ~37 days, decision ~40 days post-hearing).
• Tarion's current average claim duration is not directly published post-2024 CSS reforms; the 2019 AG figure of up to 18 months is now stale.
• The May 2026 builder-website Tarion-display sample is illustrative (~10 builders); a full audit needs browser-rendering (May 2026 builder-website Tarion-disclosure audit — Tridel/Minto/Tamarack have dedicated Tarion pages; Daniels/Brookfield/Empire less explicit; cleanest pattern is per-project warranty workflow).
