Executive Summary: Key Legal and Evidentiary Issues

• Enforceability of a personal guarantee signed by a sophisticated commercial guarantor to secure a cinema company’s overdue lease and film payment obligations to IMAX.
• Significance of an alleged oral assurance by IMAX’s president that the guarantee was “for auditor reassurance only” and “had no real enforceability,” in light of a comprehensive entire-agreement / no-representation clause in the guarantee.
• Impact of the absence of contemporaneous documentary support, delay in raising the alleged side agreement, and the inherent improbability of the alleged representation on the court’s assessment of credibility.
• Proper use of the application procedure under Rule 14 where a respondent claims there is a “material fact in dispute” and seeks a full trial with viva voce evidence.
• Application of the doctrine of unconscionability to a personal guarantee given by a well-educated, legally trained businessperson with access to counsel and a clear commercial benefit from the arrangement.
• Consequences of undisputed indebtedness under commercial lease and related agreements, and the resulting judgment against both the corporate debtor and the personal guarantor for over $2 million plus interest and costs to be determined.

Factual background

IMAX Corporation entered into a series of commercial agreements with Cinémas Guzzo Inc. under which IMAX leased projection systems and supplied IMAX films for use in Cinémas Guzzo’s theatres. In exchange, Cinémas Guzzo undertook to make lease payments for the systems, pay certain film-related sums, and remit a percentage of revenue generated by IMAX films shown in its cinemas. Over time, Cinémas Guzzo fell into arrears and failed to comply with its payment obligations. IMAX issued multiple Notices of Default in 2023 and 2024, but initially refrained from full enforcement, granting indulgences and deferrals while the parties attempted to manage the indebtedness.

The personal guarantee structure

To address growing concerns about non-payment, IMAX sought further assurance. Instead of imposing a new payment plan requiring immediate and weekly payments from Cinémas Guzzo, IMAX accepted a personal guarantee from the company’s CEO and co-owner, Vincenzo Guzzo. On July 22, 2024, Guzzo executed a personal guarantee in favour of IMAX, covering all amounts then due and owing from Cinémas Guzzo to IMAX as well as any future amounts that would become due. Guzzo, who holds degrees in economics and law and is a sophisticated businessman, had access to legal advice; indeed, the signed guarantee was transmitted to IMAX by Cinémas Guzzo’s lawyer. The guarantee therefore formed part of a broader commercial restructuring in which IMAX agreed not to insist on more onerous immediate payments in return for personal security from Guzzo.

Continuing defaults and commencement of the application

Despite the personal guarantee, Cinémas Guzzo continued to default on its obligations after July 2024. On December 6, 2024, IMAX demanded payment from Guzzo under the guarantee. No payment was made. IMAX’s counsel then sent a further formal demand to both Cinémas Guzzo and Guzzo in February 2025. Those demands also went unsatisfied. IMAX ultimately commenced an application in the Ontario Superior Court of Justice seeking judgment against Cinémas Guzzo for the outstanding debt and against Guzzo personally under the guarantee. As of January 15, 2026, the outstanding indebtedness was quantified at $2,094,842.25, and the respondents did not dispute either the amount or that Guzzo had signed a guarantee broad enough to cover all of Cinémas Guzzo’s obligations to IMAX.

The alleged side representation and evidentiary dispute

In response to the application, Guzzo filed an affidavit in August 2025 asserting that, before he signed the personal guarantee, IMAX’s Global President, Mark Welton, had orally assured him that the guarantee was only to reassure IMAX’s auditors so that the receivable would not be written off and that the guarantee would be treated like a minimum margin figure of $15,000 with “no real enforceability.” This claim, if accepted, would suggest a side agreement purportedly undermining the legal force of the document on which IMAX was suing. However, there were no contemporaneous emails, texts or documents recording this alleged conversation, no clear particulars of where or when it occurred, and no earlier written reference to it despite several critical enforcement steps by IMAX. Guzzo did not raise the alleged assurance when IMAX first demanded payment under the guarantee in December 2024, in the February 2025 lawyer’s demand letter, on service of the Notice of Application in April 2025, or even in his text correspondence with Welton around the commencement of proceedings. Welton, for his part, categorically denied ever making any such representation, both in his affidavit and under cross-examination. The court also noted that it would be contrary to Welton’s and IMAX’s obligations as officers of a public company to informally promise non-enforcement of a material receivable with no apparent benefit to IMAX and significant potential jeopardy for Welton personally.

Contractual terms and the effect of the entire-agreement clause

The personal guarantee itself contained a critical contractual provision: Article 8.1 stated that no representations affecting the guarantor’s liability had been made, other than those expressly set out in the guarantee. This is a standard “entire agreement” or “no representations” clause designed to prevent parties from later relying on alleged prior oral assurances that are inconsistent with the written instrument. Relying on this clause and relevant appellate authority, the court held that even if Welton had made the oral assurance Guzzo described, such a statement would not undermine or negate the enforceability of the written guarantee. In other words, any pre-contractual representation about non-enforceability that conflicted with the express terms of the guarantee would be contractually excluded and could not be used to defeat IMAX’s claim. That conclusion meant the alleged conversation, while a factual assertion, did not rise to the level of a material fact that could change the legal outcome of the application.

Use of the application procedure and the “need for a trial” argument

Guzzo argued that his allegation about Welton’s oral assurance created a disputed material fact that could only be resolved at a full trial where the judge could hear oral evidence and “look the witnesses in the eye” to determine credibility. He urged the court to convert the application to an action and order a one-day trial. The judge rejected this procedural objection on several grounds. First, at a prior case conference in September 2025, both sides—including the respondents—had agreed that the matter was suitable to proceed by application, and an endorsement recorded that the respondents did not object to that route. Second, Rule 14 of the Rules of Civil Procedure allows an application where material facts are not likely to be in dispute requiring a trial, language the court interpreted in parallel with the summary judgment test of whether there is a “genuine issue requiring a trial.” The judge emphasized that the 2018 amendment to Rule 14.05(3)(h) introduced the phrase “requiring a trial,” signalling that a trial is not the default procedure and that courts may, in appropriate cases, resolve disputes on the application record even if some facts are contested.

Credibility assessment without viva voce evidence

The court considered existing authority on when applications may be fairly decided on affidavits and cross-examinations alone, as well as guidance on evaluating credibility without over-reliance on a witness’s demeanour. The judge noted that bald, uncorroborated assertions that are implausible and inconsistent with the surrounding probabilities can be rejected on the paper record. Guzzo’s allegation about the supposed assurance was undermined by the absence of any documentary support, his prolonged delay in raising it, the absence of any mention in communications when enforcement began, the lack of any rational reason for Welton to make such a risky promise, and Welton’s categorical denial. Applying the principle that credibility must be assessed against the “preponderance of probabilities” in the factual and commercial context, the judge found Guzzo’s allegation not credible or reliable and concluded that no trial was required to dispose of the dispute.

Unconscionability challenge to the guarantee

Guzzo also contended that the personal guarantee should be set aside as unconscionable. The court applied the modern two-part test for unconscionability: unequal bargaining power that prevents one party from adequately protecting their interests, and an improvident bargain that unduly advantages the stronger party or disadvantages the more vulnerable party at the time of contracting. On the evidence, Guzzo could not demonstrate either element. There was no suggestion that his ability to understand or negotiate the guarantee was impaired; he was highly educated, business-savvy, and had ready access to legal advice through in-house counsel, who in fact handled the return of the signed document. He was invited to comment on the form of the guarantee and chose not to seek changes. Nor was the bargain improvident at the time it was made. The guarantee was not presented as a take-it-or-leave-it ultimatum; instead, it was one of two options offered by IMAX. Guzzo affirmatively chose to give a personal guarantee as an alternative to IMAX demanding significant immediate payments and/or tightening credit. This choice allowed Cinémas Guzzo to continue receiving IMAX films and generating revenue, and reduced immediate financial pressure on the company. The court highlighted that unconscionability does not serve as a device for parties to escape a deal merely because it later becomes onerous or circumstances change; the focus is on fairness at the time of agreement, not on subsequent hardship.

Outcome and monetary consequences

Having rejected the alleged side representation and the procedural plea for a trial, and having found that the personal guarantee was not unconscionable, the court concluded that the guarantee was valid and enforceable against Guzzo. Because the amount of Cinémas Guzzo’s indebtedness to IMAX was undisputed, the judge granted judgment in favour of IMAX against both Cinémas Guzzo and Guzzo personally, in accordance with the relief sought in the Notice of Application. The quantified amount outstanding as of January 15, 2026 was $2,094,842.25, and that sum was ordered to bear pre-judgment interest under the lease agreements and their amendments, plus post-judgment interest at the statutory rate under the Courts of Justice Act. The question of costs was left open: the parties were encouraged to agree on costs, failing which IMAX could serve short written cost submissions, to be answered by the respondents. As a result, IMAX Corporation is the successful party, and it obtained judgment for at least $2,094,842.25 in principal plus pre- and post-judgment interest, with any costs award still to be fixed later, so the exact total monetary recovery including costs and all interest cannot yet be fully determined from this decision alone.
