What is an assignment sale in Ontario real estate, and is it a good idea for buyers and sellers? If you’ve been shopping for pre-construction condos or townhomes in Pickering, Ajax, or anywhere across the GTA, you’ve likely encountered the term. Assignment sales are one of the most misunderstood transactions in Ontario real estate — but in the right circumstances, they can be an excellent opportunity for both the person selling and the person buying. Here’s everything you need to know.

What Is an Assignment Sale in Ontario Real Estate?

An assignment sale (or “assignment of purchase and sale”) occurs when the original buyer of a pre-construction property — the “assignor” — sells their contractual rights in the Agreement of Purchase and Sale (APS) to a new buyer (the “assignee”) before the original closing date.

In practical terms: the assignor signed a pre-construction APS with a builder, paid deposits, and now — before the building is complete and before they take title — they are selling those rights to you. You “step into their shoes,” assume the original agreement with the builder, and close on the property as if you were the original buyer.

Assignment sales are most common in pre-construction condominium and townhome markets, and they are particularly prevalent in pre-construction heavy communities like Pickering and across Durham Region, where significant development has occurred over the past decade.

How Does an Assignment Sale Work in Ontario? Step by Step

Step 1: The Assignor Gets Builder Permission

Most pre-construction agreements in Ontario contain a clause requiring the buyer to get the builder’s written consent before assigning. Some builders permit assignment freely; others charge an assignment fee (typically 1–2% of the purchase price), require that the assignment happen within a certain window, or restrict assignments altogether. The original buyer must review their agreement carefully and get builder approval before listing the assignment for sale.

Step 2: Listing and Marketing the Assignment

Assignment sales are often listed on MLS in Ontario (with the builder’s permission) or marketed off-market through real estate agents who specialize in this type of transaction. The listing price for an assignment is typically the original purchase price plus a “profit” or “premium” that reflects the appreciation in value since the original APS was signed — in some cases, this appreciation can be substantial, particularly in hot markets like Pickering.

Step 3: Assignment Agreement

Once a buyer is found, both parties sign an Assignment Agreement — a separate contract that transfers the rights and obligations of the original APS from the assignor to the assignee. The original APS with the builder remains in place; the assignee simply replaces the assignor as the purchaser.

Step 4: Deposits and Payments

The assignee typically reimburses the assignor for all deposits already paid to the builder, plus pays any agreed-upon profit or premium. The exact structure depends on the deal. These funds are typically held in trust by the real estate brokerages until completion.

Step 5: Closing with the Builder

At the original closing date, the assignee closes the transaction with the builder as the new buyer — completing the final payment, registering the unit, and taking title. From this point, it’s a standard purchase.

Assignment Sale Ontario Real Estate: Pros and Cons for Buyers

Advantages for Assignment Buyers

• Buy into a sold-out project: If a pre-construction building is fully sold, an assignment may be your only way to purchase a unit in that specific building at that price point.
• Potentially better pricing than resale: Assignment prices are sometimes below what a unit would sell for on the resale market after registration, since the assignor is transacting privately and the market hasn’t fully corrected to post-occupancy pricing.
• Shorter wait time: If you’re buying an assignment close to the original closing date, you may take possession sooner than if you’d bought a new pre-construction unit from scratch.
• New unit quality: You’re still getting a new unit — builder’s warranty, modern finishes, no deferred maintenance.

Risks and Considerations for Assignment Buyers

• HST complexity: Assignment sales in Ontario have significant HST implications. If you plan to rent the unit out (rather than occupy it yourself), you may not qualify for the new housing HST rebate, which can add $20,000–$40,000 to your effective closing cost. This must be reviewed carefully with a real estate lawyer and accountant before signing.
• No cooling-off period for buyers: Unlike buying directly from a builder (which has a 10-day statutory cooling-off period), assignment buyers do NOT automatically have a statutory cooling-off period. Any conditions must be negotiated into the assignment agreement — which is why having an experienced agent and lawyer is critical.
• Financing complexity: Not all lenders finance assignment purchases, and the financing terms can differ from standard mortgages. Confirm your financing options before going firm on an assignment.
• The original agreement still governs: You’re bound by all terms of the original APS between the assignor and the builder — including any caps or uncaps on development charges, closing cost structures, and interim occupancy conditions.
• Due diligence on the original APS: Your lawyer must review the original agreement in full. Hidden costs, unfavourable terms, or permission restrictions in the original APS become your problem as the assignee.

Assignment Sale Ontario Real Estate: Pros and Cons for Sellers (Assignors)

Advantages for Assignment Sellers

• Exit before closing: Life changes — job relocation, financial circumstances, or simply a change in plans. An assignment allows you to exit a pre-construction agreement before the closing obligations hit.
• Capture appreciation: If values have risen since you signed the original APS (as often happens in rising markets), you can realize that gain through an assignment premium without ever closing on the unit.
• Avoid carrying costs: If you didn’t intend to hold the property as a rental and can’t sell it immediately on the resale market post-closing, an assignment avoids closing costs, land transfer tax, and months of carrying costs.

Risks for Assignment Sellers

• Tax on profit: The CRA treats the profit from an assignment sale as fully taxable income — not as a capital gain. If you’re selling for a profit of $100,000, expect to pay ordinary income tax on that amount. Proper tax advice before entering an assignment sale is essential.
• Builder restrictions: Not all builders permit assignment — and some that do charge significant fees or restrict the timing. Check your original agreement before making any plans.
• Market risk: If values have fallen since you signed (as happened in the 2022–2024 correction), you may find that buyers are unwilling to pay the original price, let alone a premium. In a soft market, assignment sales can be difficult to complete.

Is an Assignment Sale a Good Idea?

The answer depends entirely on your specific situation — your tax position, financing options, the terms of the original APS, the current market conditions, and your goals. There’s no universal answer. What is universal is the need for experienced, independent professional advice before entering any assignment transaction — whether as buyer or seller.
