Buying a Pre-Construction Condo in Ontario: The Legal Steps

Buying a pre-construction condo in Ontario is fundamentally different from buying a resale home — the legal process is longer, more complex, and involves risks and protections that don't exist in a standard transaction. You're not just buying a property; you're buying a promise that a property will exist, and the legal framework around that promise matters enormously.

This article walks through the key legal stages every pre-construction buyer should understand, from the moment you sign in the sales office to the day you hold the title to your unit.

Stage 1: Signing the Agreement of Purchase and Sale

In a pre-construction purchase, the builder's sales team presents you with an Agreement of Purchase and Sale (APS) — a thick, heavily drafted document prepared by the builder's lawyers. It governs everything: the unit specifications, the purchase price, the deposit structure, your rights on delay, and what happens if the project is cancelled.

Have a Lawyer Review the APS

The most important thing you can do at this stage is have your own real estate lawyer review the APS before you sign, or immediately after. The agreement heavily favours the builder as drafted. Your lawyer can identify:

• Delay and termination clauses: Most builders include provisions allowing them to delay closing by months or years, or to terminate the agreement under certain conditions, without the same penalties that would apply to a buyer who walks away.
• What "finishes" means: Specifications for flooring, cabinetry, and appliances often contain language like "or equivalent substitute at the builder's discretion." Your lawyer can flag how binding those finishes actually are.
• Capping clauses for closing costs: Builders charge buyers a share of certain closing costs (development levies, utility hookups, etc.). Some agreements cap these costs; others are open-ended. Your lawyer will identify what you may be on the hook for.
• Assignment rights: If you want the option to assign (sell) your contract before closing, the APS needs to permit it. Many builder agreements restrict or prohibit assignment, or charge an assignment fee.

Stage 2: The 10-Day Cooling-Off Period

Ontario law gives pre-construction condo buyers a 10-day cooling-off period under the Condominium Act, 1998. Starting from the date you receive a copy of the fully signed APS (and all required disclosure materials), you have 10 calendar days to rescind the agreement — cancel it outright — for any reason, with no penalty and a full refund of any deposit paid.

This cooling-off period is a critical consumer protection. Use it. Even if you feel confident in the purchase, this is the window to have a lawyer review the agreement, reconsider the project, or confirm your financing is actually in place. Once the 10 days expire without you rescinding, you are bound by the agreement.

Stage 3: Deposits

Pre-construction purchases require substantial deposits, paid in instalments over the time it takes the building to be constructed — which can span several years. A typical deposit structure might require payments at signing, 30 days, 90 days, and 120 days after signing, totalling 15–25% of the purchase price (sometimes more on luxury or high-demand projects).

Deposit Protection Under Tarion

Ontario's Tarion Warranty Corporation (now operating under the Home Construction Regulatory Authority, or HCRA) administers deposit protection for new home and condo purchases. Deposits paid on a pre-construction condominium are protected up to specified maximums — as of writing, verify the current coverage limits at tarion.com, as they are adjusted periodically.

If the builder becomes insolvent, is unable to complete the project, or fails to close for certain reasons, Tarion's deposit protection may reimburse your deposit up to the covered maximum. Note: Tarion deposit protection is not unlimited, and for higher-end units where the deposit exceeds the coverage cap, you may have exposure above that threshold. Your lawyer can advise on the risk profile for your specific purchase.

Stage 4: Construction and Delays

Pre-construction projects almost never close on the originally advertised date. The Condominium Act and related regulations allow builders to extend the closing date by providing proper notice within prescribed timelines. Builders typically have the ability to push closing forward by a year or more under their "outside closing date" provisions.

What this means for buyers:

• Your mortgage pre-approval expires. A pre-approval issued today may not be valid by the time your unit is ready in two or three years. You will need to re-qualify for a mortgage at whatever interest rates exist at the time of closing.
• Market conditions change. The value of your unit at closing may differ significantly from what you paid at the time of signing.
• Your personal circumstances change. Life circumstances (employment, family, finances) may be very different by the time the project is ready.

If a builder delays beyond the "outside closing date" (or cancels the project), buyers may have rights to rescind and receive deposit refunds — but the specific rights depend on the APS terms and the applicable statutory framework. Your lawyer can assess your rights in the event of a significant delay or cancellation.

Stage 5: Interim Occupancy

In a condominium, there is a unique stage called interim occupancy that does not exist in freehold purchases. This occurs when the builder has completed your unit but the condominium corporation has not yet been formally registered under the Condominium Act. You cannot legally own your unit — title cannot be transferred — until the condo is registered.

During interim occupancy, you are permitted to move into your unit, but you are technically a tenant of the builder, not an owner. You pay interim occupancy fees — a monthly amount covering:

• Interest on the unpaid purchase price (calculated at a rate set by regulation, not market rates).
• Estimated condominium maintenance fees for the building.
• Estimated property taxes for the unit.

You do not pay down any mortgage principal during interim occupancy; your purchase funds are still locked up until final closing. Interim occupancy periods vary — sometimes a few weeks, sometimes many months — depending on how long it takes the builder to register the condominium.

Stage 6: Final Closing

Final closing occurs when the condominium is registered and title to your specific unit is transferred to you. This is when:

• Your mortgage funds are advanced.
• You pay the balance of the purchase price (less deposits already paid).
• Your lawyer registers the transfer and your mortgage in the land registry.
• Land Transfer Tax (and Toronto MLTT if applicable) is payable.

Closing Costs on a New Build

Pre-construction condo closings typically involve additional costs beyond those in a resale transaction:

• HST on new residential units: New condos are subject to HST. If the unit is your principal residence, you may qualify for the HST New Residential Rebate, which significantly reduces the tax payable. If you plan to rent the unit rather than occupy it, the HST treatment differs — get tax advice early. Verify current rebate conditions with your lawyer and the CRA.
• Development levies and education levies: Charges the municipality imposes on the builder, which are typically passed to buyers. The APS will specify whether these are capped or open-ended.
• Utility connection fees and meter charges: Charged by the builder for connecting your unit to utilities.
• Tarion enrollment fee: A fee for registering your unit under Tarion's new home warranty.
• Legal fees and disbursements: Your lawyer's fees for the final closing work.

These costs can total tens of thousands of dollars on a new condo purchase, on top of the original purchase price.
