The $250,000 Mistake Hidden in Plain Sight

In the rush to secure a unit in Markham's booming pre-construction market, most buyers focus on the floor plan, the view, and the deposit structure. But the real danger lies in the fine print — specifically, the assignment clause.

The Precedent: The landmark case of Mattamy Homes v. Ishola (2024) set a shocking precedent. A buyer was ordered to pay $190,000 in damages plus forfeit a $60,000 deposit — totaling $250,000 — simply for attempting to assign their pre-construction contract without strict adherence to the builder's restrictive terms.

The Reality: With over 60 active pre-construction projects in Markham and the massive 2,052-unit Cornell community coming online along Highway 7, assignment questions are exploding. Yet, most buyers don't realize that "assigning" your contract isn't a right — it's a privilege that builders can revoke or penalize heavily.

What Is an Assignment Clause?

An assignment clause allows you to sell your pre-construction contract to another buyer before the building is completed and registered. This is a common strategy for investors looking to capitalize on appreciation during the construction phase. However, builders include strict conditions to control this process.

Typical restrictions include:

  • Builder Approval: The builder must approve the new buyer, often charging an administrative fee ranging from $1,500 to $5,000.
  • Marketing Restrictions: You cannot advertise the unit for sale on public platforms like MLS, Realtor.ca, or social media without explicit permission.
  • Price Caps: Some clauses limit the profit you can make on the assignment, requiring you to share a percentage with the builder.
  • Timing Limits: Assignments may only be permitted during a specific window (e.g., after 50% of units are sold but before occupancy).

⚠️ The "No Public Marketing" Trap

The most common violation is listing the unit on public websites. Builders argue this undermines their own sales efforts. If caught, they can terminate your contract, keep your deposit, and sue for damages — exactly what happened in the Ishola case.

Why This Matters More in 2026

The Markham pre-construction market is shifting. With interest rates stabilizing but remaining higher than the 2020–2021 lows, some early investors are looking to exit their contracts before closing. This surge in assignment attempts has made builders more aggressive in enforcing these clauses.

The 12 Red Flags to Check Before You Sign

Before you sign any pre-construction APS in Markham, review these 12 critical clauses. If any are missing or unclear, consult a real estate lawyer immediately:

  1. Assignment Fee: Is there a fixed fee? How much is it?
  2. Approval Process: What are the criteria for builder approval of the new buyer?
  3. Marketing Rights: Can you list on MLS? Can you use social media?
  4. Profit Sharing: Does the builder claim a % of your assignment profit?
  5. Timing Window: When exactly can you assign? Is there a blackout period?
  6. Termination Rights: Can the builder cancel your contract if you violate the clause?
  7. Deposit Forfeiture: What happens to your deposit if the assignment fails?
  8. HST Responsibility: Who pays the HST on the assignment sale?
  9. Legal Costs: Are you responsible for the builder's legal fees during the assignment?
  10. Occupancy vs. Title: Can you assign after occupancy but before final title registration?
  11. Buyer Qualification: Must the new buyer meet the same financial criteria as you?
  12. Exclusivity: Does the builder have the right of first refusal to buy back the unit?

How to Protect Yourself

Don't rely on the sales representative's verbal assurances. Everything must be in writing. Here's your action plan:

  • Hire a Real Estate Lawyer: Before signing, have a lawyer specializing in pre-construction reviews your APS. The $500–$1,000 fee is cheap insurance against a $250,000 loss.
  • Negotiate the Clause: While builders are often rigid, some may allow more flexible assignment terms if requested early in the sales process.
  • Document Everything: Keep records of all communications with the builder regarding assignment permissions.
  • Understand the Tax Implications: Consult with a CPA to understand how HST and capital gains apply to your specific assignment scenario.
