Lloyd v. Baker, 2026 ONCA 434 (CanLII)
How Lloyd v. Baker Redefines Limitation Period Deadlines in Personal Injury Claims
In motor vehicle collision claims, determining whether an action has been initiated within the mandatory two-year limitation period often hinges on discoverability, specifically, when the plaintiff knew or ought to have known that their injuries met the “permanent and serious impairment” threshold under the Insurance Act.
The Ontario Court of Appeal decision in Lloyd v. Baker provides clarity on what this looks like in practice, offering vital guidance for personal injury lawyers evaluating the viability of a claim and managing limitation period risks.
The case arose from a motor vehicle collision in November 2015. Six years later, in November 2021, the respondent, Ms. Lloyd, commenced an action against the appellant, Mr. Baker, claiming damages for injuries sustained in the collision.
Mr. Baker brought a summary judgment motion arguing that the action was statute-barred under the Limitations Act. The motion judge dismissed the motion, finding that the claim commenced within two years of when Ms. Lloyd subjectively knew her injuries met the threshold.
The Ontario Court of Appeal allowed the appeal and dismissed the action, concluding that the motion judge erred in his legal analysis of discoverability based on the available medical evidence.
Like many personal injury claimants, Ms. Lloyd had a pre-existing concussion stemming from a workplace injury. While recovering, she was involved in the 2015 motor vehicle collision, which caused a second concussion. Although she initially believed she would fully recover and return to normal life, her symptoms persisted.
Medical records from the years following the collision painted a clear picture of ongoing struggles:
- Ms. Lloyd repeatedly reported physical and cognitive problems that affected her daily life, and received ongoing treatment from family doctors and specialists without complete success.
- While she returned to work in January 2016, she did so only on reduced hours and modified duties, never returning to full-time regular duties.
- Shortly after the collision, a treating physician noted the second head injury had aggravated her initial concussion. Diagnosed with post-concussion syndrome, Ms. Lloyd was advised by her doctor on December 1, 2016, that she might “never reach 100% or previous baseline.” In March 2018, another physician opined it was “unlikely” any treatment would suddenly “cure” her condition.
- November 28 to 29, 2019, Ms. Lloyd was assessed by a neuropsychologist, Dr. Day, who formally diagnosed a “mild neurocognitive disorder due to a traumatic brain injury” in a March 2020 report. During a follow-up meeting in July 2020, Ms. Lloyd claimed Dr. Day informed her she had suffered “permanent damage” (a point disputed by Dr. Day).
Following the July 2020 meeting with Dr. Day and the completion of the expert report, Ms. Lloyd consulted a lawyer and a statement of claim was issued on November 8, 2021, nearly six years post-collision.
The Court of Appeal reaffirmed key principles regarding discoverability and limitation periods in personal injury claims.
First, regarding discoverability and the statutory threshold, under Section 4 of the Limitations Act, a proceeding cannot be commenced after the second anniversary of the day the claim was discovered. In motor vehicle collision claims, Section 5, discoverability, must be read alongside the statutory deductible and the “serious permanent impairment” threshold under Section 267.5 of the Insurance Act (Sanei v. Debarros, 2024 ONCA 104). Meaning, the limitation period begins when the claimant knows, or reasonably ought to have known, that their injuries exceed these thresholds.
Second, a plaintiff does not need to know the full extent of their injury to trigger the limitation period (Peixeiro v. Haberman, [1997] 3 S.C.R. 549), as it is settled law that a cause of action is established as soon as it is reasonably discoverable that the injury meets the threshold.
Third, certainty of success is not the test because the Limitations Act “does not distinguish between meritorious and non-meritorious claims” (Andrews v. Pattison, 2022 ONCA 267). Consequently, a plaintiff does not need an expert opinion explicitly confirming the threshold has been met, nor do they need to be certain of success at trial for the clock to start running.
Finally, while Ms. Lloyd asserted she did not realize her injuries were permanent until her July 2020 meeting with Dr. Day, the Court of Appeal held that this subjective view was unreasonable in light of the objective evidence, noting that she had experienced continuous, debilitating symptoms for years and that her family doctors had warned her as early as 2016 that she might never return to her pre-collision baseline.
Crucially, the court noted that unlike cases involving unexpected complications or a sudden shift from minor to serious symptoms, Ms. Lloyd’s condition had been serious and unremitting from the outset.
