How Are Damages Calculated When a Contract Is Broken?Winning a breach of contract claim does not automatically mean receiving every dollar anticipated under the agreement. In Hamilton v. Open Window Bakery, the Supreme Court of Canada examined how contractual termination rights affect damages.
The plaintiff had an agreement to provide services to a bakery for a fixed period. The contract also permitted the bakery to terminate the relationship earlier by giving specified notice. The bakery ended the agreement improperly, leading to litigation.
The Court confirmed that where an agreement allows alternative methods of performance, damages are generally assessed using the method least burdensome to the defendant.
The assessment therefore focused on the performance the plaintiff was contractually entitled to receive, rather than a prediction that the bakery would probably have continued the relationship for the full term.
The early termination provision mattered because it formed part of the parties’ bargain. Compensation could not simply be calculated as though that provision did not exist. The case demonstrates the importance of reading payment obligations together with the contractual rights that qualify them.
What this could look like in practice
Consider a hypothetical consulting agreement described as a two-year contract. A consultant reviewing a potential claim might initially calculate the remaining monthly fees through the end of the second year.
However, the agreement might also contain a clause allowing termination on notice. Before relying on the initial calculation, the consultant and lawyer would need to examine that wording and its relationship to the other provisions.
A useful financial summary would separate amounts already earned but unpaid, anticipated future fees, expenses, payments received, and any replacement work. That would provide a clearer starting point than a single total based solely on the contract’s stated duration.
The takeaway
Keep the complete agreement, including schedules and amendments, when seeking advice. Identify the clause you believe was breached and explain how you calculated the requested compensation. A clear distinction between the breach and the resulting financial claim can make discussions about litigation or settlement more focused and productive.
