Executive Summary: Key Legal and Evidentiary Issues

• The appeal turned on whether the term "Maximum Contract Amount" in a 10-year services agreement fixed a payment ceiling or established a guaranteed minimum.
   
• Appellants argued that the chambers judge failed to properly weigh extrinsic evidence, including a financing proposal and pre-contract correspondence, when interpreting the agreement.
   
• Clauses 3.01, 3.03, and 3.04 of the Services Agreement were each examined for their bearing on whether compensation was capped, guaranteed, or both.
   
• Contractual interpretation principles from Sattva Capital Corp. v Creston Moly Corp. governed the court's analysis of the parties' objective intentions at formation.
   
• Cross-appellants sought dismissal of the originating application on procedural grounds, a question the chambers judge never reached.
   
• Ultimately, the Court of Appeal found no palpable and overriding error in the chambers judge's interpretation of the contract.
   

Facts of the case

Lloyd Good and West Central Air Holdings Ltd. sold their aerial crop-spraying business to Precision West AG Corp., which operates as Provincial Airways and West Central Air (2013). As part of the transaction, the parties entered into a Services Agreement under which Good and West Central Air Holdings would provide post-sale management and aircraft maintenance services in the Rosetown, Saskatchewan area over a 10-year term. James Russell Wood and James Pottage guaranteed Precision West's obligations under the agreement. Clause 3.01 set compensation on a per-acre basis: $1.50 per acre for the first 165,000 acres sprayed annually and $2.00 per acre for acres sprayed beyond that threshold. Clause 1.01 defined "Maximum Contract Amount" as $2,000,000, or an amount up to $2,100,000 if adjusted under clause 3.03. Over the agreement's 10-year term, Precision West paid the appellants $1,475,505.54, exclusive of GST. After the agreement expired, the appellants submitted an invoice to Precision West for $551,518.54, inclusive of GST, which Precision West did not pay. The appellants then commenced their claim by originating application, in which they sought the difference between the $1,475,505.54 already paid and $2 million, contending that the Maximum Contract Amount functioned as a guaranteed minimum payment rather than merely a ceiling.

Policy and legislative provisions at issue

Three clauses of the Services Agreement were central to the dispute. Clause 3.01 established the per-acre compensation formula described above. Clause 3.03 addressed the final year of the contract, requiring the appellants to notify Precision West once total compensation reached 95% of the Maximum Contract Amount, at which point the parties could negotiate an increase; the clause specified that the total amount payable could never be decreased below the Maximum Contract Amount or increased above 1.05 times that amount. Clause 3.04 obliged Precision West to maintain a life insurance policy on Lloyd Good's life, with proceeds payable to Precision West equal to the outstanding balance of the "Maximum Contract Price" [sic — the defined term in the agreement is "Maximum Contract Amount"] as of each year-end; the clause further provided that if the Termination Date occurred because of Good's death, Precision West would pay West Central Air Holdings Ltd. the difference between amounts already paid under clause 3.01 and $2,000,000. The appellants also relied on extrinsic materials — a negotiation Proposal, a financing proposal Precision West presented to its lenders, and a March 2013 email from Mr. Good referencing a "minimum annual management payment" — arguing these supported their reading of the Maximum Contract Amount as a floor.

Reasoning and analysis

Writing for a unanimous court, Justice Caldwell applied the framework from Sattva Capital Corp. v Creston Moly Corp., 2014 SCC 53, under which contract interpretation requires reading the agreement as a whole and giving its words their ordinary and grammatical meaning in light of the surrounding circumstances known to the parties at formation. Because the chambers judge's interpretation was a question of mixed fact and law, the Court of Appeal owed it deference absent an extricable question of law and would intervene only if the appellants established a palpable and overriding error. On the factual matrix, the court held that the chambers judge had expressly considered the extrinsic evidence — the Proposal, the financing documents, and Mr. Good's 2013 email — but permissibly concluded that none of it displaced the plain wording of the agreement, since evidence of one party's subjective negotiating intentions cannot override the objective meaning of the executed contract. Regarding clause 3.01, the court agreed that the per-acre payment structure showed an intention to tie compensation to performance rather than guarantee a fixed sum, noting that a genuinely fixed-price arrangement would have entitled the appellants to $2 million even if no acres had been sprayed. Turning to clause 3.03, the court found that the provision addressed only a possible mid-term cap adjustment and created no obligation to pay the full $2 million regardless of performance. As for clause 3.04, the court concluded that the life-insurance provision was not probative of whether the Maximum Contract Amount operated as a floor, since those proceeds were payable only upon Mr. Good's death and were disconnected from ordinary performance-based compensation under clause 3.01. Having reviewed each clause together with the definition of "Termination Date" in clause 1.01, the court held that the agreement, read as a whole, established only a maximum amount payable.

Ruling and overall outcome

The Court of Appeal dismissed the appeal, finding that the appellants had not established an error of law or a palpable and overriding error of fact or mixed fact and law in the chambers judge's conclusion that the Services Agreement fixed a maximum, not a minimum, compensation amount. Because the respondents' cross-appeal concerned a procedural ground for dismissal that became moot once the appeal was dismissed on the merits, the court also dismissed the cross-appeal without commenting on its substance. The respondents — Precision West AG Corp., James Russell Wood, and James Pottage — were the successful parties on the appeal and were awarded one set of costs on Column 4 of the Tariff of Costs; the court made no order as to costs on the cross-appeal.
