Short answer
Yes. Tarion says new freehold purchasers must notify it within 45 days of signing beginning April 1, 2026. Tarion also says the reduced-coverage consequence for late registration is deferred during a transition until January 1, 2027.
The buyer’s real concern
A buyer assumes the builder handles every warranty step. Months later, the buyer cannot easily confirm that Tarion knows about the agreement or whether maximum deposit protection applies.
What the official rule or guidance says
Tarion introduced an online purchase-registration process. Its current Q&A distinguishes the April 1, 2026 registration requirement from the later date when reduced deposit-coverage consequences are scheduled to take effect.
What this protection does not guarantee
Registration does not validate the builder contract, guarantee closing or insure every dollar paid. Condo and contract-home deposit arrangements are different. The builder’s receipt is not a substitute for the buyer keeping a complete record.
A practical Ontario example
Illustration only: A freehold buyer signs September 1, 2026. The prudent step is to register within 45 days even though Tarion’s transition may defer the reduced-coverage consequence, rather than depending on that transition.
What to do now
Register promptly using the Home ID, save confirmation and verify the agreement and payment schedule. Ask the lawyer whether every amount is legally characterized and protected. Tell the broker if future deposits will reduce funds available for appraisal shortfall or closing costs.
Questions to ask before the deadline
- Which document or delivery date starts the legal deadline?
- What can the builder change, delay, charge or refuse under the agreement?
- Could occupancy fees, adjustments or a lower appraisal create a cash shortfall?
- Will the mortgage approval and rate hold still be valid at final closing?
- Which issue needs a lawyer, accountant, inspector, appraiser or mortgage broker?
Rajiv’s broker perspective
A builder purchase creates two timelines: the legal contract and the future mortgage closing. A cooling-off right or warranty protection cannot replace a financing plan, and today’s pre-approval cannot guarantee the appraisal or income position years later. I would test the future closing conservatively, keep the buyer’s credit and funds traceable, and prepare A, alternative/B and—only where sensible—short-term MIC or private fallback options before the deadline becomes urgent.
