In Poole v. Poole, , 2026 ONSC 1545[1], Justice Rees addresses a familiar scenario in estates and property litigation: siblings jointly owning a family cottage whose relationship has broken down. The decision reinforces two consistent themes in Ontario law: courts are reluctant to enforce informal family arrangements as binding contracts, and a co-owner’s right to sale under the Partition Act[2] is difficult to resist absent compelling evidence.
Facts
The dispute arose between two brothers, Gregory and James Poole, who jointly owned a cottage with their mother as joint tenants.[3] Following their mother’s death in 2019, the property passed to the brothers by right of survivorship.
The brothers and their families continued to use the cottage together for a period of time, but their relationship eventually deteriorated.
James offered to purchase Gregory’s interest in the cottage.[4] When that did not resolve matters, Gregory commenced an action alleging[5]:
- an oral agreement between the brothers not to sell the cottage before 2033
- a second oral agreement governing time-sharing of the property
- interference with his use and enjoyment of the cottage, including harassment
James denied these claims and counterclaimed for sale of the property under the Partition Act, bringing a motion for summary judgment.[6]
Issues
The Court considered four central issues[7]:
- Whether there was a genuine issue requiring a trial regarding the alleged oral agreement not to sell the cottage before 2033;
- Whether there was a binding agreement respecting time-sharing;
- Whether James’ conduct constituted actionable interference with Gregory’s use and enjoyment of the property; and
- Whether there was any basis to deny James’ presumptive right to sale under the Partition Act.
Analysis
Justice Rees held that there was no genuine issue requiring a trial and that the matter could be fairly determined on the paper record using the Court’s enhanced fact-finding powers.[8] The issues were straightforward, and summary judgment was a proportionate means of resolving the dispute.[9]
1. No Agreement Not to Sell the Cottage Before 2033
No credible evidence of an oral agreement
Gregory’s claim rested largely on a bare assertion in his affidavit that the parties had agreed not to sell the cottage until 2033. The Court found this evidence unpersuasive.
His discovery evidence introduced shifting explanations for the alleged agreement, including references to family values and, alternatively, an attempt to shield the asset from James’ divorce.[10] Critically, Gregory failed to adduce corroborating evidence, including from his spouse, whom he claimed had witnessed relevant discussions.[11]
The Court preferred James’ evidence and found it implausible that he would agree to restrict the sale of a significant asset for years without documentation or consideration.
Surrounding circumstances did not support the claim
Gregory’s reliance on surrounding circumstances was also rejected.
The transfer of the property reflected a gratuitous transfer from their mother to her sons as joint tenants.[12] Her will did not address the cottage, as it passed outside the estate by right of survivorship.[13] There was no evidence that she intended to restrict the brothers’ ability to deal with the property.[14]
The Court concluded that no such agreement existed.
2. No Binding Time-Sharing Agreement
The Court found that no enforceable agreement existed governing the brothers’ use of the cottage.[15]
At most, the evidence showed that the parties attempted to coordinate their respective use of the property following a falling out between their families.[16] These arrangements were informal and never reduced to writing.
Justice Rees held that such arrangements are properly characterized as social agreements, grounded in mutual trust and convenience, rather than legally binding contracts.[17] Courts are slow to impose contractual obligations in these circumstances.
3. No Actionable Interference with Use and Enjoyment
No nuisance claim available between joint tenants on these facts
Gregory alleged that James’ conduct amounted to nuisance.
The Court rejected this claim, confirming that nuisance requires an indirect interference originating outside the claimant’s land. Here, both parties were using the same jointly owned property. The alleged interference was therefore “direct” and not actionable in nuisance.[18]
Alleged conduct did not meet the threshold
In any event, the alleged conduct did not rise to the level of substantial or unreasonable interference.[19]
The evidentiary record did not support claims of harassment.[20] Text messages were relied upon by Gregory but were not properly before the Court, and even if considered, were not threatening or intimidating in tone.[21]
Other complaints – including James attending at the cottage, repositioning a boat lift, repainting a room, and performing maintenance – were found to be trivial or beneficial to the property.[22] None amounted to actionable interference.
4. No Basis to Refuse Sale Under the Partition Act
James, as a joint tenant, had a presumptive right to seek partition or sale.[23]
The Court emphasized that it has very limited discretion to refuse such relief.[24] To do so, the responding party must demonstrate malicious, vexatious, or oppressive conduct, or some other sufficient reason, such as a binding agreement restricting sale.[25]
Gregory established neither.
There was no enforceable agreement preventing sale, and while Gregory had a genuine sentimental attachment to the cottage, that was not a sufficient legal basis to deny relief.
Disposition
The Court granted the summary judgment, and the cottage could be sold under the Partition Act.
Despite allegations that Gregory advanced baseless claims, including fraud, the Court declined to award substantial indemnity costs. James was awarded partial indemnity costs of $49,420.35, which the Court found reasonable and fair.[26]
Final Thoughts
Poole v. Poole is a clear illustration of the limits of informal family arrangements in property disputes.
Absent cogent and supported evidence of a binding agreement, courts will not enforce understandings rooted in family dynamics. At the same time, the decision reaffirms the strength of the Partition Act: where co-ownership becomes untenable, a party seeking sale will generally succeed.
The case also serves as a cautionary reminder that advancing unsubstantiated claims, particularly in an effort to resist sale, may result in summary dismissal and significant costs consequences.
