Guarantee vs Indemnity: How to decide if you need to comply with the GAA
Introduction
In WBI Home Warranty Ltd. v Optimistix Management Inc., 2024 ABCJ (“WBI”) and Trisura Guarantee Insurance Co. v North American Steel Erectors Inc., 2023 ABKB (“Trisura”), Alberta courts revisited the distinction between guarantees and indemnities in the context of compliance with the Guarantees Acknowledgement Act, RSA 2000, c G‑11 (the “GAA”).
The central issue in both cases was whether the defendants’ obligation was a guarantee requiring compliance with the GAA, or an indemnity which would fall outside the scope of the GAA. This is an important distinction because the GAA requires that where an individual gives a guarantee, that individual must obtain independent legal advice and sign the guarantee in front of a lawyer. If an individual provides an indemnity, no such requirement for independent legal advice exists.
When a labelled indemnity will be treated as a guarantee
In WBI, the plaintiff brought a claim against defendants who had signed an “indemnity agreement” in connection with a builder’s obligations under home warranty policies. Under the agreement, the individuals agreed to indemnify WBI for losses arising where the builder failed to repair defects or otherwise breached its obligations.
The defendants argued that, despite the label, the agreement was in substance a guarantee, and therefore unenforceable because the formal requirements of the GAA had not been met. The formal requirements being that the guarantors would need to obtain independent legal advice and execute the guarantee in front of a lawyer. The Applications Judge found that it was a guarantee and thus the GAA had to be followed. Since no independent legal advice was obtained, the court determined it was unenforceable and WBI could not pursue an indemnity claim against the individual defendants.
WBI appealed and the Court of King’s Bench allowed the appeal, finding that the agreement was an indemnity rather than a guarantee. The Court emphasized that the characterization of an agreement depends on the substance of the transaction and the parties’ obligations, not simply whether liability is triggered by another party’s default. The defendants were directors, officers and/or shareholders of the builder who stood to benefit from the builder obtaining the warranty insurance necessary to conduct its business. Their promise to indemnify Royal & Sun Alliance Insurance Company of Canada (RSA) was part of the consideration that induced RSA to assume that insurance risk.
The Court also found that the defendants’ obligation was separate from the builder’s obligation to repair defects. RSA could proceed directly against the indemnitors without first exhausting its remedies against the builder, and their liability was joint and several. These features were characteristic of an indemnity. Accordingly, the GAA did not apply and the failure to comply with its execution requirements did not make the agreement unenforceable.
The key takeaway is that a court will look beyond the “indemnity” label to the substance and commercial context of the obligation. A third party’s default may trigger an obligation without necessarily making that obligation a guarantee.
Despite default, the indemnity holds
In Trisura, the plaintiff sought to enforce an indemnity agreement against individuals following losses paid out under a construction bond after the contractor’s default. The defendants argued that the obligation should be treated as a guarantee, on the basis that it was triggered by the contractor’s failure to perform, and was therefore unenforceable due to non‑compliance with the GAA.
The Court rejected that argument, holding that the fact the obligation was triggered by another party’s default did not automatically transform it into a guarantee. Relying on settled Alberta law, the Court confirmed that the agreement remained an indemnity and was enforceable despite non‑compliance with the GAA. In particular, the Court found that the numbered operative provisions of the agreement, being clauses 1 through 34, clearly created an indemnity under Alberta law.
The Court also considered “Special Instructions” in the agreement that referred to complying with the GAA, Those instructions appeared in small italicized font after the agreement’s 34 numbered provisions and immediately below the signature blocks. They appeared alongside other instructions concerning the proper execution of the agreement by corporations and partnerships. The Court considered this placement and context significant and concluded that the Special Instructions were directed at the proper execution of the agreement and ensuring that the persons or entities signing it were bound, rather than defining the substantive nature of their obligations.
The Court interpreted the instruction to comply with the GAA as a precaution intended to protect Trisura in the event that the agreement was subsequently characterized as a guarantee. It was not a contractual term providing that compliance with the GAA was a condition precedent to enforcement of the agreement regardless of its proper characterization. Accordingly, non-compliance with the instruction created a risk to Trisura if the agreement was ultimately found to be a guarantee, but did not render an otherwise valid indemnity unenforceable.
The Court ultimately found that the agreement was a true indemnity, and the failure to comply with the GAA did not provide a defence. The decision confirms that the characterization of the obligation turns on the substantive rights and obligations created by the operative provisions of the agreement, rather than simply the fact that the indemnitors’ liability was triggered by another party’s default or that the agreement contained precautionary instructions referring to the GAA.
Key Takeaways
The cases confirm that the analysis focuses on the proper characterization of the obligation, specifically whether the liability is secondary and contingent on another party’s default or primary and independent. A guarantee is a secondary obligation, where one party agrees to answer for another’s default, and liability arises only upon that default. If an obligation is characterized as a guarantee and the GAA is not complied with, it is unenforceable. By contrast, an indemnity creates a direct obligation to compensate for loss, independent of any third party’s performance. Thus, an indemnity sets out that the indemnitor is directly liable regardless of whether another party is in default or not. Since the obligation exists by itself, it is an indemnity and does not need to comply with the GAA.
The distinction is determined by substance, not form. Courts will assess how the obligation operates in practice rather than how it is labelled, focusing on whether liability is contingent on default or arises independently.
