Facts of the case

Industrial Scaffolding Inc. (ISI) applied for a stay of an arbitration award pending a judicial review application scheduled to be heard on February 18, 2027. The underlying dispute concerned ISI's use of non-union workers in residential construction. ISI argued that when it signed the Voluntary Recognition Agreement (VRA2013) on May 27, 2013, the United Brotherhood of Carpenters and Joiners of America, Local 579 (the Union) lacked jurisdiction over residential-sector work, though ISI conceded that signing the VRA2013 bound it to the applicable Collective Agreement between the Construction Labour Relations Association (CLRA) and the Union. At arbitration, ISI disputed that its non-union employees performed work within the Union's trade jurisdiction and claimed the Union's damages claim was excessive and punitive. ISI also argued it was denied procedural fairness when the arbitrator refused to postpone the hearing despite four witnesses becoming unexpectedly unavailable. The arbitrator ultimately found that ISI violated the Collective Agreement by employing non-union members, that the CLRA Collective Agreement applied to residential-sector scaffolding work, that ISI failed to remit required union dues, and that ISI breached dispatch and hiring procedures. The arbitrator ordered ISI to pay the Union $477,198.28, covering the period from August 2023 to August 2025.

Policy and legislative provisions at issue

The application engaged section 54(1) of the Labour Relations Act, R.S.N.L. 1990, c. L-1, which defines the scope of voluntary recognition agreements binding an employer to a union across sectors of the construction industry. ISI's underlying judicial review grounds included alleged misapplication of the Parol Evidence Rule and failure to apply estoppel principles in determining the scope of ISI's voluntary recognition of the Union. The Personal Property Security Act, S.N.L. 1998, c. P-7.1, was relevant to the evidentiary record, since ISI tendered a PPSA report showing a general security agreement over its assets in favour of the Business Development Bank of Canada. The stay itself was assessed against the three-part test from RJR MacDonald v. Canada (Attorney General), [1994] 1 S.C.R. 311: whether there is a serious issue to be tried, whether the applicant would suffer irreparable harm if the stay were refused, and where the balance of convenience lies.

Reasoning and analysis

On the first RJR factor, the Court applied a low threshold, asking only whether ISI's grounds were frivolous or vexatious. The Union conceded that some of ISI's grounds met this threshold, including procedural fairness concerns arising from the denial of a postponement and the alleged misapplication of the Parol Evidence Rule, though it maintained that ISI's challenge to the retroactive damages calculation lacked a stated legal or factual basis. The Court found ISI met the threshold for a serious issue to be tried. On irreparable harm, the Court reviewed ISI's financial records, including 2025 financial statements showing accounts receivable of $912,210 (with roughly $534,641 tied up in an ongoing mechanic's lien claim), a shareholder's equity of approximately $700,000 composed largely of receivables and capital assets, and a cash flow deficiency of $457,067 for the year ended December 31, 2025. ISI also cited an outstanding CRA debt of $540,176.16, serviced through monthly payments of $25,000 for GST/HST and $25,000 for payroll remittances. The Court accepted evidence, including statements from ISI's principal Leroy Coffey, that ISI lacked cash reserves and that selling capital assets to fund the award would impair its operations and risk triggering loan defaults, concluding that business failure was a realistic, non-speculative risk if the stay were refused. On balance of convenience, the Union argued its prima facie entitlement to the award favoured denying the stay, while ISI pointed to the absence of evidence that Union members would be harmed by delayed payment and to the proximity of the scheduled February 18, 2027 hearing. The Court found the balance favoured ISI.

Ruling and overall outcome

Justice Muzychka granted ISI's application, ordering that the arbitrator's decision be stayed pending the outcome of the judicial review. ISI was the successful party on the stay application. The decision does not award or quantify any monetary sum in ISI's favour; rather, it suspends enforcement of the arbitrator's prior award of $477,198.28 against ISI until the judicial review is determined. Costs of the stay application were ordered to be in the cause.
