Buyers Walked Over “Sewage Concerns.” The Court Called It a $212K Breach.
Insights from Switzer v. Petrie, 2023 ONSC 5115

Real Estate Law. Real-World Lessons.
Every week, Ontario courts deliver decisions that reshape how real estate deals play out - impacting your closings, commissions, and client relationships. But who has time to sift through 50+ pages of legalese?
We do.
Clause & Effect breaks down Ontario’s biggest real estate cases into clear, practical takeaways for realtors, mortgage advisors, and investors. No fluff. No Latin. Just sharp lessons you can actually use.
Let’s dive in!
What happens when buyers casually pull the plug on a real estate deal just ten (10) days before closing, then blame the sellers for not waiting around for a better price?
In Switzer v. Petrie, buyers ditched an $810,000 home purchase citing vague "unforeseen consequences," leaving sellers scrambling and forcing a quick resale for $600,000. The court had to decide: Did the sellers jump the gun, or did the buyers’ last-minute bailout justify the speedy sale?
The Case: One Cancellation, Two Weeks, and $210K Gone
On May 14, 2022, Scott and Kathleen Petrie agreed to buy Lloyd and Violet Switzer’s residential property for $810,000, depositing $15,000. Closing was set for July 14, 2022.
Just ten (10) days before closing, the Petries pulled out due to vague "unforeseen consequences," leaving the Switzers in a bind. Specifically, they claimed they weren’t provided with a promised property survey and discovered the property's municipal sewage system relied on a "trash pump," raising doubts about plumbing reliability. Despite these concerns, they failed to substantiate their claims properly in court.
The Switzers immediately relisted at $699,900, and after two weeks, and with only one offer, they accepted a sale at $600,000, closing on August 19, 2022. They then sued the Petries for their losses ($210,000) plus costs.
The Court Showdown: Hasty Resale or Reasonable Action?
The buyers argued:
The Switzers acted too hastily, selling below market value.
The sellers failed to mitigate properly, rushing to accept a low offer.
A trial with expert market analysis was necessary to determine fair value.
The sellers countered:
They acted reasonably to mitigate their losses.
They properly exposed the home to the open market through a realtor.
The quick sale was the best, and in fact, the only offer they received.
The Decision: Seller Wins - Quick resale was reasonable
Justice Nicholson sided squarely with the Switzers:
No evidence of improvidence: The quick resale was at arm’s length, properly listed, and reasonable under market conditions.
No duty to wait indefinitely: Sellers aren't expected to gamble that a better offer will come along.
Burden of proof on buyers: The buyers failed to provide any real evidence (like expert appraisals or cross-examinations) to support claims of improper mitigation.
Result: Sellers awarded full damages of $212,302.11, offset by the $15,000 deposit.
Key Takeaways (Without the Legalese)
1/ Quick resale allowed if reasonable.
Lesson: If buyers bail, sellers don’t have to wait for top dollar - just a reasonable offer from an open market.
2/ Arm’s-length sales are strong proof of market value.
Lesson: Courts typically accept the resale price as fair unless there’s concrete evidence it was improvident or rushed.
3/ Buyers must actively challenge mitigation.
Lesson: If buyers dispute resale fairness, they must promptly provide real evidence, not just opinions, to challenge sellers’ decisions.
