A recent decision from the Ontario Court of Appeal, Thiessen v. Thiessen Estate, 2026 ONCA 730, has clarified the applicable limitation period for certain claims against estates, particularly those involving real property. The case centered on a dispute between a surviving spouse and the estate of his deceased wife regarding a claimed beneficial ownership interest in her residence. This ruling underscores the critical importance of timely action in estate litigation, especially when asserting property rights.

The couple married in March 2014, and a year later, in March 2015, they executed a marriage contract after receiving independent legal advice. This agreement outlined their intention to sell their individual homes and jointly acquire a new property as tenants in common. However, they were unsuccessful in finding a suitable new residence, leading them to decide to reside in the wife's existing home. In June 2016, the husband sold his own property, depositing $223,000 into their joint bank account the following month. On the very same day, the wife transferred $100,000 from this joint account to her three children. The husband contended that this financial contribution entitled him to a 50-percent beneficial ownership share in the wife's residence. Despite this, the property's title remained solely in the wife's name, and neither the marriage contract was amended nor any joint ownership registered.

Following the wife's passing in January 2022, the husband initiated legal proceedings against her estate in April 2024, seeking recognition of his claimed beneficial ownership interest in the property. The deceased's will had provided him with a conditional life interest in the residence, with the remainder interest designated for her children upon its termination. Concurrently, the husband also pursued a claim for dependant support under the Succession Law Reform Act, which the Superior Court ultimately dismissed in September 2024, deeming it statute-barred.

Subsequently, the estate trustees filed a motion under Rule 21 of the Rules of Civil Procedure, asserting that the husband's property claim was also time-barred. The motion judge, in their initial ruling, dismissed any claim for damages under the Trustee Act. However, the judge permitted the husband's constructive trust claim to proceed, applying the ten-year limitation period stipulated by the Real Property Limitations Act (RPLA), thereby allowing the claim to move forward. This decision set the stage for the appeal, as the estate trustees argued that the Trustee Act should have governed the entire claim.

The Ontario Court of Appeal, in its review, sided with the estate trustees, concluding that the two-year limitation period prescribed by the Trustee Act applies to the husband's claim. The court determined that the Trustee Act takes precedence for claims against estates that stem from alleged wrongs for which the deceased would have been liable, even when these claims involve real property, unless a specific statutory exception is met. The appellate court identified the alleged contractual or equitable wrong as having occurred when the deceased failed to register the husband's claimed ownership interest after the $100,000 payment was made.

The court explicitly rejected the husband's argument that the estate trustees, rather than the deceased, were responsible for the relevant wrong. Furthermore, the claim did not fall within the statutory exception for claims to recover land or rents involving express trusts vested in a trustee. The court noted that the alleged agreement to substitute the existing residence for the contemplated jointly purchased property was oral and had not been documented in either the marriage contract or the deceased's will. Emphasizing that equitable trust claims are not automatically exempt from the Trustee Act, the court affirmed that the nature of the alleged injury, rather than the specific remedy sought, dictates the applicability of the statute. Relying on the precedent set in Ingram v. Kulynich Estate, 2024 ONCA 678, the court reiterated that specific limitation provisions governing estate claims supersede the general provisions of the RPLA concerning land recovery. Consequently, the appeal was allowed, and the husband's property claim was deemed statute-barred. The court did not address the estate trustees' alternative argument that the claim lacked a reasonable cause of action.

This decision from the Ontario Court of Appeal carries significant weight for estate law practitioners and individuals pursuing claims against estates in Ontario. It unequivocally establishes that the two-year limitation period under the Trustee Act will generally apply to claims against an estate for alleged wrongs committed by the deceased, even when those claims seek a beneficial interest in real property. This ruling clarifies a potential ambiguity where the Real Property Limitations Act (RPLA) might otherwise suggest a longer ten-year period for land-related disputes.

The court's emphasis on the "nature of the alleged injury" rather than the "remedy sought" as the determining factor for the applicable limitation period is a crucial takeaway. This means that even if a claimant seeks a constructive trust, which typically involves real property, the underlying wrong being attributed to the deceased will trigger the shorter Trustee Act limitation. Lawyers advising on estate matters, particularly those involving property claims by surviving spouses, must be acutely aware that the Ontario Court of Appeal has affirmed the two-year limitation period under the Trustee Act takes precedence over the RPLA's ten-year period for claims against estates, even for real property. This ruling underscores the critical need for prompt action when pursuing beneficial ownership interests against an estate to avoid claims being statute-barred.
