The Pre-Construction Assignment Clause Costing Buyers $250K — And How to Protect Your Investment
With 60+ active pre-construction projects across Markham, Unionville, and York Region, assignment sales are booming. But most buyers don't realize: a single clause in your Agreement of Purchase and Sale could cost you $250,000+ in lost equity. The precedent is real — Mattamy v. Ishola — and it's reshaping how assignment transactions work in Ontario. Here's what every pre-con buyer needs to know, from Michael John Lau, Markham's top REALTOR® and pre-construction specialist.
The $250K Mistake Most Pre-Construction Buyers Don't See Coming
You signed an Agreement of Purchase and Sale for a pre-construction condo in Markham. The deposit schedule felt manageable. The completion date seemed far away. But buried in Section 12.4 — or maybe Appendix B — is an assignment clause that could lock you out of selling your contract before closing. And if you try to assign anyway? You could forfeit your entire deposit, face legal action, or lose six-figure appreciation gains.
⚠️ The Reality: In Mattamy (Markham) Ltd. v. Ishola (2023 ONSC 4127), the Ontario Superior Court upheld a builder's right to block an assignment and retain the buyer's deposit when contract terms weren't followed. The buyer lost over $250,000 in projected equity. This isn't theoretical — it's citeable precedent affecting Markham buyers today.
What Is an Assignment Clause — And Why Does It Matter?
An assignment clause governs whether — and under what conditions — you can sell your right to purchase a pre-construction unit before the building is complete. This is critical because:
- Market Shifts: If prices rise 20% between signing and closing, your contract itself has value.
- Life Changes: Job relocation, family growth, or financial changes may require an exit strategy.
- Investment Flexibility: Many buyers purchase pre-con as an investment, planning to assign before closing.
But not all assignment clauses are created equal. Some allow assignments freely; others require builder consent; some prohibit them entirely after a certain date.
In this landmark 2023 case, a buyer attempted to assign their pre-construction condo agreement without following the builder's strict procedural requirements. The court ruled:
- Contract Terms Are Enforceable: Builders can set specific conditions for assignments (written consent, fees, timing).
- Substantial Compliance Isn't Enough: Minor deviations from the process can void your assignment rights.
- Deposit Forfeiture Is Possible: If you breach assignment terms, the builder may retain your deposit as liquidated damages.
- Equity Loss Is Real: The buyer in this case lost both their deposit and the appreciated value of the contract.
Why This Matters for Markham Buyers: Mattamy, Fieldgate, Remington, and other major builders in Markham use similar assignment language. If you don't understand your clause before signing, you're signing blind.
60+ Active Pre-Construction Projects = 60+ Reasons to Pay Attention
Markham and York Region currently have over 60 active pre-construction projects — from high-rise condos in Downtown Markham to townhomes in Box Grove and detached homes in Mount Joy. Each project has its own assignment terms. Michael John Lau tracks these developments and helps buyers:
Before you sign, Michael reviews the assignment language across competing projects so you can choose flexibility that matches your goals — whether you plan to occupy, rent, or assign.
If market appreciation creates assignment value, Michael coordinates with real estate lawyers to ensure your assignment follows every procedural requirement — protecting your gains and your deposit.

Real Scenarios: Assignment Strategy in Action
📍 Downtown Markham Condo — Investor Exit
Situation: Buyer purchased pre-con in 2023; market appreciated 22% by 2026; needed liquidity
Strategy: Michael reviewed assignment clause upfront; coordinated lawyer for consent request; marketed within builder guidelines to pre-qualified buyers
Result: Assignment completed with builder approval; buyer netted $187K in equity after fees; zero legal risk
📍 Unionville Townhome — Life Change Pivot
Situation: Family relocating for work 18 months before closing; couldn't carry two properties
Strategy: Early assignment clause analysis revealed 90-day builder consent window; Michael initiated process 120 days pre-deadline
Result: Assignment approved in 3 weeks; buyer avoided carrying costs and preserved deposit; seamless transition
📍 Box Grove Detached — Avoiding the Ishola Trap
Situation: Buyer received informal assignment offer; builder's clause required written consent + $5K fee
Strategy: Michael paused the transaction, engaged lawyer, submitted formal request per contract terms
Result: Assignment approved with documented compliance; buyer protected $210K in appreciation; avoided Ishola-style forfeiture
