Citation: Deakin v. Chu, 2025 ONSC 6198
The Deal That Went Up in Smoke
In Deakin v. Chu, Justice ten Cate confronted a question that may surprise transactional practitioners: does a home seller in Ontario have a positive legal obligation to disclose the presence of cigarette smoke to potential purchasers?
The answer, at least for now, is no. However, the case offers important lessons for drafting agreements and managing client expectations in residential real estate transactions.
The Facts
The Chus, living in Ottawa, retained a realtor to help them relocate closer to family near London, Ontario. Because of the long drive, their son John viewed the seller’s Ilderton home on their behalf. Notably, the Chus themselves never physically visited the property.
In March 2022, the parties signed an unconditional agreement of purchase and sale for $993,000, with a $100,000 deposit. The agreement included two significant features: a waiver of any building inspection and a standard “entire agreement” clause. The closing date was later extended to June 30, 2022.
On June 13, 2022, just 17 days before closing, the Chus’ lawyer advised that they would not close, claiming the property had been “heavily saturated with cigarette smoke” which was allegedly not disclosed. The seller’s lawyer immediately characterized this as anticipatory breach.
The Aftermath and Damages
The timing could not have been worse for the seller. She had already purchased a replacement home in London with a June 30 closing date, relying on the Ilderton proceeds. When the Chus refused to close, she was forced to:
- Borrow funds from a friend to close on her new home
- Re-list the Ilderton property in a falling market for $799,000 (reduced from the $993,000 sale price)
- Carry the property for months with no offers
- Eventually accept $740,000 in September 2022, closing in November
Her total damages exceeded $280,000, including the price differential, carrying costs, and bridge financing interest.
The Legal Analysis
The Chus attempted to analogize their situation to established case law on latent defects posing health risks, such as cases involving radioactive waste, a convicted child pornographer living across the street, or former garbage dumps. They asked the court to find that cigarette smoke constitutes a similar undisclosed health hazard.
The Court rejected this argument on three critical grounds:
First, no reliable evidence of smoke. The defendants never visited the property themselves, and neither their son nor their realtor filed affidavits. No photographs or expert reports substantiated the claim that the home was “heavily saturated with smoke.” The seller testified she never smoked indoors, though she permitted her brother to smoke in the backyard or garage with the door open.
Second, no representations were made. Unlike the case law the Chus relied upon (wherein the court ordered the rescission of a sale due to undisclosed safety risks of prior break-ins and threats of arson), there was no evidence the seller made any representations about smoking or the condition of the property.
Third, impractical consequences. The court declined to create a positive disclosure obligation for smoke, noting the far-reaching and confusing implications: How would sellers know if guests had smoked surreptitiously? What about smoking by previous owners? How much smoke is too much?
The court found this was a matter better left to legislation rather than judicial innovation.
Summary Judgment Principles
The Court granted summary judgment, finding the defendants showed “no real chance of success” because they failed to provide reliable evidence of smoke, representations, or a genuine health hazard specific to their circumstances. The Court emphasized that self-serving affidavits without detailed facts and supporting evidence are insufficient to create a triable issue.
Key Takeaways for Transactional Lawyers
- The Importance of Inspections
This case illustrates the critical protective function of inspection conditions. Had the Chus insisted on a building inspection or simply visited the property themselves, they could have identified any concerns about smoke before committing unconditionally. When clients waive inspections, ensure they understand they’re accepting the property “as is” with very limited recourse.
- Disclosure Obligations Remain Limited
Ontario sellers still have no general duty to disclose every potential concern about a property. The obligation to disclose remains limited to situations involving fraudulent misrepresentation or responding to direct inquiries. However, sellers should never make positive representations they know to be false.
- The Risks of Remote Transactions
The Chus’ decision to rely entirely on their son’s viewing, without ever visiting themselves, proved costly. While remote purchases have become more common, clients should understand the inherent risks of buying property without seeing it for themselves first.
- Anticipatory Breach is Serious
The seller’s lawyer correctly identified the June 13 letter as anticipatory breach. When a party clearly communicates an intention not to perform before the closing date, the other party can immediately treat the contract as breached without waiting for the closing date to arrive. This allowed the seller to act quickly to mitigate her damages.
- Market Timing Matters
The case demonstrates how a falling market can dramatically increase damages from a failed transaction. The seller’s $253,000 loss was largely attributable to the market decline between June and September 2022. In today’s volatile market conditions, these risks remain very real.
Conclusion
While Deakin v. Chu may not create new law, it reinforces important principles about unconditional agreements, disclosure obligations, and the consequences of buyers’ remorse. For transactional lawyers, the case serves as a reminder that the best way to protect clients from unwanted surprises is through thorough due diligence and carefully drafted conditions, not through after-the-fact legal challenges.
