Executive Summary: Key Legal and Evidentiary Issues

• The court addressed whether a deficiency in construction holdbacks under s. 78(2) of the Construction Act should be calculated against unpaid invoices or total invoices.
   
• Both appellants, Alpa Stairs and Railings Inc. and Newmar Window Manufacturing Inc., had received full payment on early invoices but were left with unpaid balances on later ones.
   
• No subcontractor lien claimants existed at the time of the priority dispute, a fact the panel treated as central to its analysis.
   
• Justice Steele's decision below relied on the longstanding precedent in Dufferin Concrete Products v. Waterbrooke Development Ltd., which limited holdback recovery to unpaid invoices.
   
• Permitting a holdback claim on invoices already paid in full would have produced a commercially absurd double-recovery result for the contractors.
   
• Ultimately, the Court of Appeal upheld the lower court's calculation method and dismissed the appeal, awarding costs of $40,000.
   

Facts of the case

Mapleview Developments Ltd. was developing a residential townhouse project in Barrie, Ontario. Alpa Stairs and Railings Inc. and Newmar Window Manufacturing Inc. were contractors retained directly by Mapleview to supply services or materials to the project. When Mapleview defaulted on its obligations to its senior secured lender, KingSett Mortgage Corporation, the Ontario Superior Court of Justice appointed a receiver over the project on March 21, 2024. The receiver conducted a sales process, and Cavanagh J. approved a Sale Approval, Vesting and Ancillary Matters Order on August 16, 2024, approving the sale of the project to Dunsire Homes Inc. The purchase price was structured to repay KingSett in full together with amounts secured by charges ranking ahead of KingSett, including "Priority Payables" under s. 78(2) of the Construction Act. By the time of the insolvency, Alpa had submitted invoices totaling $1,100,604.80, having been paid in full for invoices before April 28, 2023, leaving a balance of $195,615.55. Newmar had submitted invoices totaling $2,924,385.76, having been paid in full for invoices before March 2, 2023, leaving a balance of $445,756.09. Each appellant registered and perfected a construction lien for its unpaid balance, and no subcontractor lien claimants existed in relation to either appellant at the time of the priority dispute. The Lien Claimants' Reserve was funded by Dunsire in the amount of $19,704,333.28 to secure payment of Priority Payables claims.

Policy and legislative provisions at issue

The dispute turned on s. 78(2) of the Construction Act, which grants liens priority over a building mortgage "to the extent of any deficiency in the holdbacks required to be retained by the owner under Part IV." Section 22(1) requires a payer to retain a holdback equal to 10 percent of the value of services or materials as they are actually supplied, until liens against the holdback are satisfied or discharged. Section 1(1) defines "holdback" as the 10 percent of value required to be withheld under Part IV, and s. 14(1) confirms that a lien arises at the time services or materials are supplied. The term "deficiency in the holdbacks" is not defined anywhere in the Act.

Reasoning and analysis

Writing for the panel, Osborne J.A. held that where an invoice has been paid in full, no lien can arise against the corresponding holdback, or if it did, it has already been satisfied, since there is no other lien claimant, such as a subcontractor, who could assert a competing claim. On this reading, once an invoice is fully paid and no subcontractor liens exist, there is no "deficiency" in the holdback relating to that invoice. The court further reasoned that even if the statutory text were ambiguous, principles of statutory interpretation would compel the same result, since accepting the appellants' position would allow contractors to recover the same 10 percent holdback twice — once through full payment of the invoice and again through a priority claim against the mortgagee. This would be commercially absurd and inconsistent with the Act's purpose of balancing the interests of lien claimants and mortgagees. The panel found this approach consistent with the reasoning in Dufferin Concrete Products v. Waterbrooke Development Ltd. and Pegah Construction Ltd. v. Panterra Mansions Joint Venture Corp., both of which limited holdback priority to unpaid invoice amounts. The court expressly limited its holding to cases where no subcontractor lien claimants exist at the time of the priority dispute, noting the result could differ if such claimants were present.

Ruling and overall outcome

The Court of Appeal dismissed the appeal, holding that any deficiency in holdbacks under s. 78(2), where no subcontractor lien claims exist at the time of the dispute, must be calculated as 10 percent of unpaid invoices only, not the full contract amount — affirming the approach taken by the motion judge below in favour of the respondent, Dunsire Homes Inc. The appellants were ordered to pay costs of the appeal in the agreed-upon amount of $40,000 all-inclusive, and the costs award made by the motion judge below was left undisturbed.
