Executive Summary: Key Legal and Evidentiary Issues

• Dispute centered on the proper method for determining the fair market value of leased land at rent reset under a long-term ground lease

• Core legal issue involved whether the arbitrator correctly applied the legal test for “highest and best use” under appraisal standards

• Arbitration award interpreted the lease to require land valuation as vacant, unencumbered, and unimproved

• Conflicting expert appraisals presented differing valuations based on office versus residential development potential

• Court granted partial leave to appeal on the question of whether the arbitrator omitted required legal elements in determining “highest and best use”

• Ultimately, the court upheld the arbitrator’s decision and found sufficient reasoning and factual basis for the $12.5 million land valuation

Facts of the case

The applicant, Place Laurier Limited (PLL), holds a 70-year ground lease from the respondent, The Manufacturers Life Insurance Company (Manulife), for land at 170 Laurier Avenue West in Ottawa. The lease involves a 14-storey office tower constructed in 1972. Under the lease terms, rent is reset periodically based on the land's fair market value, excluding any improvements and as if the land were vacant and unencumbered. Following a zoning change in 2008 that allowed for higher-density development, the parties could not agree on the land’s appraised value for the third rental period, prompting arbitration.

The arbitration and decision

Arbitrator Sydney Troister was appointed to determine the fair market value as of April 30, 2022. The parties presented conflicting appraisals: Manulife's expert valued the land at $16.17 million based on its potential for a 27-storey residential tower, while PLL’s expert valued it at $4.67 million based on continued office use. The arbitrator interpreted the lease to require valuation of the land as vacant and unencumbered, meaning its potential for redevelopment had to be considered. Although critical of both expert reports, the arbitrator concluded that the most likely highest and best use was future residential redevelopment after a buy-and-hold period. He determined the fair market value to be $12.5 million, adjusting the appraisal inputs accordingly.

Court proceedings and issues on appeal

PLL sought leave to appeal under section 45 of the Arbitration Act, 1991, claiming the arbitrator committed legal errors in his valuation. Specifically, PLL argued that the arbitrator failed to correctly apply the legal test for "highest and best use," notably by neglecting the financial feasibility and maximum return components. The court agreed that this raised an extricable question of law and granted leave on that issue, as well as on whether the arbitrator provided sufficient reasons to support his valuation conclusion.

Outcome and reasoning

The Ontario Superior Court ultimately dismissed the appeal. Justice Jensen found that while the arbitrator did not explicitly break down each component of the "highest and best use" test from the Canadian Uniform Standards of Professional Appraisal Practice (CUSPAP), his reasoning showed that all elements had been implicitly addressed. The arbitrator had sufficient evidence—including market conditions, zoning allowances, and expert critiques—to support his conclusion. The judge also confirmed that arbitrators are not strictly bound by appraisal standards when determining legal questions unless expressly required by the arbitration agreement. The court held that the arbitrator provided adequate reasons for his decision, allowing parties and reviewing courts to understand how he reached the $12.5 million valuation.

Conclusion

The appeal was dismissed, and the arbitrator’s decision was upheld. The judgment reaffirmed the high threshold for judicial intervention in commercial arbitration awards and clarified that while appraisal standards may inform the analysis, arbitrators retain discretion in applying them unless strictly required by the terms of arbitration.
