The Ontario pre-construction buyer's guide

Pre-construction in Ontario rewards preparation and punishes improvisation. The transaction is front-loaded, the decisions that determine whether it goes well are nearly all made in the first hour at a sales centre, years before you get the keys.

This guide is the whole arc, in order.

1. Understand what you are actually signing

A freehold pre-construction purchase in Ontario is a firm, binding, unconditional agreement from the moment the builder accepts it.

There is no cooling-off period. Condominium buyers get a 10-day statutory rescission right under the Condominium Act. Freehold buyers, detached, semi, townhome, get nothing. Read this first.

There is also generally no financing condition. Builders will not grant one on a home closing in three or four years, because no lender will commit that far out. Why.

So: no way out, and no financing certainty. Every protection you are going to have must be put in place before you sign.

2. Get represented, before your first visit

The builder budgets a co-operating brokerage commission whether or not you bring a broker. Walk in alone and the builder keeps it, the price does not drop. The economics.

Most builders require your broker to be registered at or before your first visit for representation to be recognised. Visit unrepresented and you often cannot add representation later. Sort this out first; it costs nothing and is irreversible in the wrong direction.

3. Know your rebate position before you shop

This is the largest number in the transaction after the price, and the current programs are unusually generous:

• Federal First-Time Home Buyers’ GST Rebate, up to $50,000, first-time buyers only.
• Ontario Enhanced New Housing Rebate, up to $80,000, and not restricted to first-time buyers.
• Ontario 5% top-up, up to $50,000, reduced by any federal rebate claimed.

Combined, up to roughly $130,000. How they fit together.

Two things to do now rather than later:

Confirm you qualify. The spousal test disqualifies more buyers than any other condition, and the consequence of being wrong is a bill from your builder at closing, not merely a missed rebate.

Note the deadline. The ENHR requires an agreement signed between April 1, 2026 and March 31, 2027. Signing date, not closing date. The deadline.

4. Get the money straight

Two separate piles, years apart:

Deposits, commonly 10% of the price on freehold, in instalments over 12 to 24 months, with the first draft due on signing. Typical structures.

Closing, land transfer tax, levies, connections, Tarion enrolment and legal fees, commonly $30,000 to $45,000 on a $1.1M home outside Toronto.

Then the items nobody budgets: appliances, window coverings, fencing and landscaping, often another $25,000 to $60,000.

And the one that ends purchases: an appraisal shortfall at closing, payable in cash with no exit.

Buy below your maximum. This is the single most protective decision available to you.

5. Choose the lot carefully

On low-rise, the lot matters more than the finishes and cannot be changed later. Premiums for permanent advantages, a walkout basement, backing onto protected land, meaningfully wider frontage, tend to hold value. Premiums for three extra feet of grass do not. Lot premiums.

Watch the interaction with the rebate bands: a premium that pushes your price past $1,500,000 can cost you the entire federal rebate. The cliffs.

6. Have the agreement reviewed before you sign

Not after. A few hundred dollars against a million-dollar irreversible commitment. What a lawyer looks for.

If one amendment is achievable, make it a cap on development charges and levies. On a four-year closing an uncapped clause is an open-ended liability decided by a municipal council. Why this one.

7. After you sign

• Deposit instalments on the contractual dates. Missing one is a default.
• Confirm Tarion registration within the first weeks, it affects your deposit protection, and freehold protection caps at 10% of price up to $100,000. Call Tarion; do not assume the builder did it. Deposit protection.
• Décor appointment, buy rough-ins, think hard about cosmetics.
• Keep your borrowing capacity intact. No new car leases. Review with your lender annually.

8. Approaching closing

Expect the date to move. Delays are normal and Tarion’s compensation caps at $7,500.

Do the pre-delivery inspection properly, two to three hours, your specifications in hand, everything written on the form. It is the warranty baseline, and it is the most consequential two hours of the purchase.

Then diarise your 30-day and year-end Tarion forms. Missing those windows forfeits claims you were entitled to.

The short version

Get represented first. Know your rebate position. Have the agreement read before signing. Cap the levies. Buy with margin. Do the PDI properly.

Let’s go through your situation before you commit to anything.
