Standard form contracts, from municipal tendering packages to CCDC agreements, are now the norm in the construction industry. They often arrive as "take-it-or-leave-it" documents: the owner or public authority sets the terms, and the contractor either signs or walks away from the work.
When disputes arise, the key issue is how courts will interpret those terms and whose interpretation governs. This has significant consequences for contractors, owners, and sureties navigating construction disputes, bond claims, and warranty obligations.
Two decisions of the Supreme Court of Canada provide guidance on how courts interpret standard form, non-negotiable contracts: Ledcor Construction Ltd. v Northbridge Indemnity Insurance Co. (“Ledcor”) and Emond v Trillium Mutual Insurance Co. (“Emond”). Both decisions concerned the interpretation of a standard form Builders’ Risk insurance policy, but the principles articulated by the Court provide useful guidance for construction parties seeking to interpret their own standard form agreements.
In Ledcor and Emond, the Court uses “standard form” to refer to contracts that are non-negotiable. While CCDC contracts are also standard form agreements, they are often amended through supplementary conditions or other negotiated revisions. Where that occurs, the contract may no longer be treated as a true standard form agreement for interpretive purposes, and different interpretive principles may apply.
Together, these decisions confirm that courts will not depart from the plain meaning of a contract simply because one party ended up with a less favourable result. Only where the language is genuinely ambiguous will further interpretive tools be applied, including, as a last resort, the doctrine of contra proferentem (Latin for “against the offeror”).
How Courts Approach Interpretation
Courts follow a structured, three-stage approach when interpreting standard form contracts:
Stage 1: Plain Meaning
The court gives effect to the language of the contract, read as a whole. If the meaning is clear, the analysis ends there.
Stage 2: Resolving Genuine Ambiguity
If the language reasonably supports more than one interpretation, the court turns to broader interpretive tools, including the reasonable expectations of the parties and the commercial realities of the industry.
Stage 3: Contra Proferentem
If ambiguity remains after Stage 2, the court may apply contra proferentem, resolving the uncertainty in favour of the party who did not draft the contract. This is a doctrine of last resort.
This staged approach reinforces that ambiguity is a threshold issue, not a starting assumption.
The Role of Non-Negotiability
A key feature of standard form contracts is that they are not negotiated. As a result, the usual focus on the parties’ specific intentions carries less weight, since there is little or no negotiation to inform that analysis. Courts instead look to broader considerations such as the purpose of the contract, the nature of the relationship it creates, and the industry in which it operates.
An interpretation applied to a standard form contract may therefore carry across multiple projects where the same form is used, subject to project-specific differences.
What This Means in Practice
For contractors and owners, the takeaway is straightforward.
Courts will not search for ambiguity to relieve a party from a bad bargain. The wording of the contract will govern unless it reasonably supports more than one interpretation.
Where a contract is non-negotiable, ambiguity may ultimately be resolved against the drafting party. However, that protection is limited and will not apply where the contract was negotiated or amended.
In particular, the use of a CCDC standard form contract does not automatically engage contra proferentem, especially where the contractor has had the opportunity to amend the terms.
The Bottom Line
Together, Ledcor and Emond confirm a disciplined yet commercially realistic approach to standard form contracts. Courts begin with the ordinary meaning of the contract’s language and enforce it as written unless genuine ambiguity remains. Only where ambiguity persists will courts turn to broader interpretive tools and, if necessary, apply contra proferentem.HOW WE CAN HELP
