Executive Summary: Key Legal and Evidentiary Issues

• Dispute focused on proper calculation of loss of future earning capacity after a motor vehicle accident.

• Trial judge disregarded expert economist’s report and instead applied a fixed annual loss approach.

• Appellant argued that statistical averages and compounding effects were misapprehended.

• Respondents maintained that the judge’s method was reasonable despite omission of expert data.

• Court of Appeal found both factual and legal errors in the trial decision.

• Damages were significantly reassessed to reflect more realistic future earnings.

Facts and outcome of the case

Background of the dispute
The case arose from a 2015 rear-end motor vehicle collision in which Jessica Tiemer struck the vehicle driven by Alissa Laurin. Liability was admitted, leaving damages as the sole issue in dispute. Laurin claimed that her injuries reduced her ability to earn income at the same level she had achieved before the accident, and the key point of contention became how her future earning capacity should be valued. At trial, expert economic evidence was presented to assist in projecting Laurin’s income losses over time.

Trial court’s decision
The trial judge chose not to rely on the expert economist’s analysis and instead calculated Laurin’s loss of future earning capacity using a constant annual loss model. This method did not account for factors such as wage growth, statistical earning averages, or compounding effects. As a result, the court awarded Laurin $463,289 for future income loss. Laurin appealed, contending that the trial judge had failed to properly interpret and apply the economic evidence presented.

Issues before the appellate court
The Court of Appeal examined whether the trial judge erred in law and fact by disregarding the expert report, failing to incorporate statistical averages into the analysis, and underestimating Laurin’s pre-accident earning trajectory. A central question was whether the judge had substituted an overly simplistic approach in place of the more rigorous method supported by the expert evidence.

Findings of the appellate court
The appellate court determined that the trial judge’s approach was flawed. By ignoring the economist’s projections, the court underestimated the likely impact of Laurin’s injuries on her lifetime earnings. The appellate court emphasized that proper calculation of loss of earning capacity requires consideration of realistic income progression, wage growth, and compounding factors, rather than reliance on a static annual figure. The court concluded that Laurin’s pre-accident earning potential had been significantly undervalued.

Revised award
Having found errors in both fact and law, the appellate court reassessed damages. The award for loss of future earning capacity was increased substantially from $463,289 to $1,000,000. This reassessment better reflected the economic realities of Laurin’s situation and ensured her future losses were more accurately compensated. No separate order for appeal costs was specified.
