Buying Pre-Construction in Ontario: What the Contract Means

The short answer

• You are signing a builder-drafted contract, not buying a home and the two are governed by very different rules.
• The Condominium Act’s 10-day cooling-off period starts once you have received the agreement, the disclosure statement and the Condo Buyers’ Guide.
• A real estate lawyer should review the agreement during those 10 days, not after, because that is the only window to walk away cleanly.
• Deposits, closing costs, occupancy dates and assignment rights are set by the builder’s paperwork, so read them closely.
• Cancelling after the cooling-off period ends is difficult and can put part or all of your deposit at risk.

Buying Pre-Construction in Ontario Means Signing a Contract First

When you buy a resale condo, you’re buying something that exists. You walk through it, you see the finishes, you get an inspection if you want one and on closing day the title transfers. Pre-construction works differently. You’re signing an agreement of purchase and sale for a unit that might not be built for years.

That agreement is drafted by the builder’s lawyers, not yours. It sets out the price, the deposit schedule, the estimated occupancy date, the finishes you’re entitled to and dozens of clauses about delays, cost adjustments and cancellation rights that often favour the builder. Buying pre-construction in Ontario is really an exercise in contract law long before it becomes an exercise in real estate.

This matters because a lot of buyers treat the signing appointment like they’d treat an offer on a resale home: read it quickly, sign where indicated, move on. With pre-construction, that approach can cost you tens of thousands of dollars down the road in unexpected closing adjustments or a development that stalls for years.

What Ontario’s 10-Day Cooling-Off Period Actually Does

The Condominium Act gives buyers of new condo units a 10 calendar day cooling-off period. The clock starts only after you have received three documents: the purchase agreement, the builder’s disclosure statement and the Condo Buyers’ Guide from the Condominium Authority of Ontario. During those 10 days you can cancel with no penalty and get a full refund of your deposit.

The point of the cooling-off period isn’t to give you time to change your mind about the colour of the countertops. It exists because pre-construction agreements are long and complicated and most buyers sign first and only start asking questions afterward.

Ten days sounds like plenty of time, but it moves fast once you account for weekends, work schedules and the time it takes a lawyer to review a long document. If you’re seriously considering a project, the smart move is lining up your lawyer before you sign anything, not after.

What Counts as Cancelling in Time

To cancel within the cooling-off period, you need to give notice to the builder before the 10 days expire. Your lawyer can tell you the correct way to do it. Telling your sales rep you’ve changed your mind may not be enough on its own. Your lawyer can prepare and send the notice if it comes to that, which is one more reason to have one lined up early rather than scrambling on day nine.

Why the Cooling-Off Period Is When a Lawyer Should Read the Agreement

A lot of buyers assume their lawyer’s job starts near closing, when it’s time to review the final statement of adjustments. With pre-construction, that’s backwards. My guide to closing costs covers what a resale closing involves. The agreement you sign at the sales centre is the document that determines almost everything that happens afterward and once the cooling-off period ends, you’re bound by it.

A lawyer experienced in pre-construction deals is looking for things a buyer typically wouldn’t catch:

• Development charges, levies and utility hookup fees that can add to your closing costs and whether they are capped.
• Occupancy date language that separates “interim occupancy” from actual closing, during which you pay occupancy fees but don’t own the unit. Per HCRA, interim occupancy fees cover interest, estimated property taxes and maintenance and do not count toward your purchase price.
• Assignment clauses that restrict or heavily fee-load your ability to sell the contract before closing if your plans change.
• Delay and termination clauses that let the builder push dates or cancel the project under fairly broad conditions.
• Deposit structure and whether it’s held in trust as required and how it’s insured.

This is precisely the kind of review that has to happen inside the 10-day window. Once it closes, you can still ask a lawyer for advice, but you’ve lost your ability to walk away without penalty and any changes you want now require the builder’s cooperation rather than your legal right to cancel.

Deposits, Tarion and Where Your Money Actually Sits

Pre-construction condo deposits in Ontario are usually paid in installments on a schedule set out in your agreement and the structure varies by builder and project. By law, condo deposits must be held in trust. If a builder terminates the agreement and does not return your deposit within 10 days, Tarion provides protection of up to $20,000.

Freehold new homes have different limits and the rules can change, so confirm the details with your lawyer rather than a sales brochure. Don’t assume your whole deposit is protected. Ask and get it in writing.

Pre-Construction vs Resale: What You’re Actually Buying

Factor	Pre-Construction Condo	Resale Condo
What you sign	Builder-drafted purchase agreement for a future unit	Agreement of purchase and sale
Cooling-off period	10 calendar days under the Condominium Act	None, offer is binding once accepted (subject to conditions)
Closing costs	Development charges, levies and adjustments often uncapped	Land transfer tax, legal fees and adjustments can be estimated in advance
Timeline to ownership	Set by the builder’s estimated occupancy and closing dates	Set by the closing date in the accepted offer
Ability to see the unit	Model suite or floor plan only	Full in-person viewing and inspection possible
Exit before closing	Assignment sale, if the agreement permits it	Not applicable, you own the unit outright at closing

Where Pre-Construction Prices Actually Come From

Pre-construction prices are set by the builder based on projected costs, expected market conditions years out and how quickly they want to sell out a project. Early “VIP” access pricing can be set to generate momentum, which does not necessarily reflect market value at completion.

This means the price you sign at today has no fixed relationship to what the unit will be worth when it finally closes. Values can move either way over a multi-year build timeline, so a unit may appraise below the price you agreed to pay, which can affect your financing. This is a real risk worth discussing with both your lawyer and your mortgage professional before you commit deposit money.

Assignment Sales: Your Exit Ramp, If the Contract Allows It

Life can change over a multi-year building timeline. Buyers sometimes need to sell their contract before the building closes, which is called an assignment. Not every pre-construction agreement allows this and the ones that do may charge a builder consent fee or restrict how the assignment is marketed.

If there’s any chance your circumstances might change before closing, ask specifically about the assignment clause before you sign and have your lawyer explain exactly what it permits. This is not a detail to discover after you’ve already committed thousands of dollars in deposits.

What to Do Next

• Before visiting a sales centre, line up a real estate lawyer who specifically handles pre-construction condo deals, not just resale closings.
• If you sign, calendar the 10-day cooling-off deadline immediately and get the agreement to your lawyer within the first day or two, not the last.
• Ask the builder directly about development charge caps, occupancy fee schedules and assignment rights before you sign and get answers in writing where possible.
• Confirm with your lawyer how your deposit is held and what Tarion protection applies to your specific unit and project.
• Read my new construction guide and talk to your mortgage professional about how a multi-year closing timeline could affect your financing and appraised value at completion.

If you’re weighing a pre-construction purchase in the Ontario market, I’d rather you ask the awkward questions now than discover the answers at closing.
