Executive Summary: Key Legal and Evidentiary Issues

• Scope of an associate judge’s jurisdiction to restrict future discovery motions as a term of an order in a Rule 76 (simplified procedure) action.
• Proper interpretation and interaction of Rules 1.05, 37.13 and 37.16 of the Rules of Civil Procedure in limiting parties’ ability to bring motions.
• Whether a court can impose a leave requirement for discovery motions absent a motion by a party or any finding of frivolous, vexatious, or abusive conduct.
• Procedural fairness concerns arising from making a significant procedural order without prior notice to the parties or an opportunity for submissions.
• The relationship between case-management efficiency (controlling “motions culture”) and the parties’ rights to discovery and to be heard.
• Appellate review of discretionary procedural orders, including the standard of review for jurisdictional errors and breaches of natural justice.

Background and facts of the underlying dispute

Aenos Food Services Inc. commenced an action in Ontario under the Rule 76 simplified procedure, alleging lawyer’s negligence against individual lawyer Emily Tierney and her firm, Tierney Stauffer LLP. The core dispute in the pleadings involved the scope of the defendants’ retainer, including what they were hired to do, what advice they gave, and what instructions they received from Aenos. In the statement of defence, the law firm pleaded, among other things, an oral retainer agreement, advice allegedly provided to the client, and instructions allegedly given by Aenos. Aenos, as plaintiff in the underlying action, brought a motion before an associate judge seeking particulars of several paragraphs of the defence. It wanted more detail on three main categories: particulars of the alleged oral retainer arrangement, particulars of the legal advice said to have been given, and particulars of the instructions Aenos supposedly gave. Aenos argued it could not know the full case it had to meet, or decide whether to deliver a reply, without those particulars, and it criticized the defence as containing bald allegations without material facts.

The motion for particulars and the associate judge’s order

The associate judge dismissed Aenos’ motion for particulars. She held that the requested information was largely within Aenos’ own knowledge and that the defence pleaded sufficient material facts; the further information sought was more in the nature of evidence than pleading-level fact. She placed the dispute in the context of the Rule 76 simplified procedure, emphasizing that this regime is designed to streamline litigation, reduce cost, and prevent actions from getting mired in unnecessary interlocutory steps. The associate judge expressed concern about “motions culture,” noting that the case had stalled at the pleadings stage due to the fight over particulars and that a more practical and cost-effective route would have been to move directly to early document exchange and examinations for discovery, as suggested by the defence. Exercising her discretionary power, she refused to order any of the requested particulars and went further. To “ensure that this matter moves forward effectively and does not get further bogged down at the discovery stage,” she ordered that the parties must obtain leave of the court before bringing any discovery motions. Leave was to be sought by way of a case conference before her.

Appeal and issues raised

Aenos appealed, but notably did not challenge the dismissal of its motion for particulars. Instead, the appeal targeted only the additional term of the order that restricted discovery motions without leave. Aenos argued that the associate judge lacked jurisdiction to impose such a restriction in the absence of a motion by any party and without satisfying the conditions in Rule 37.16, which expressly governs orders prohibiting further motions without leave. It also argued that the order was made without notice and without an opportunity for submissions, thereby breaching procedural fairness. Further, Aenos said there were no findings of frivolous or vexatious conduct, no evidentiary basis for a leave requirement, and inadequate reasons explaining the legal basis for the restriction. In the alternative, it alleged a palpable and overriding error in the associate judge’s finding that the action had been delayed by the particulars dispute. The respondents, although they did not oppose the appeal, had previously supported the associate judge’s concern about keeping the matter moving; in their submissions below, they had requested a timetable for exchanging documents and conducting examinations for discovery “so that this matter can be moved along.” On appeal, both sides accepted that the usual Housen v. Nikolaisen standards applied: correctness for questions of law and palpable and overriding error for factual findings and discretionary exercises.

Jurisdiction to make the discovery-motion restriction

The appellate judge first addressed whether the associate judge had jurisdiction to impose a restriction on discovery motions as part of her disposition of the particulars motion. He reviewed the statutory framework governing associate judges. As statutory officers, associate judges derive their powers from the Courts of Justice Act and the Rules of Civil Procedure, not from inherent jurisdiction. Section 86.1(6) of the Courts of Justice Act and Rule 37.02(2) confirm that associate judges may hear motions and, subject to certain exceptions, have the same jurisdiction as judges on motions. The appellant argued the only proper route for an order restricting further motions was Rule 37.16, which allows a judge or associate judge, “on motion by any party,” to prohibit a party from bringing further motions without leave where that party is attempting to delay, add to costs, or otherwise abuse the process through a multiplicity of frivolous or vexatious motions. Because neither party had brought such a motion, and because there was no finding of abusive or vexatious conduct, Aenos submitted that the associate judge could not rely on Rule 37.16 and had no alternative route to impose a leave-to-bring-discovery-motions requirement. The appellate judge, however, distinguished the situation from the classic Rule 37.16 scenario. He noted that this was not a case of multiple frivolous motions or an attempt to shut down a vexatious litigant across the board. The order did not bar all motions; it was limited to discovery motions and arose in a Rule 76 file, where the Rules themselves already restrict discovery (for example, prohibition of written examinations for discovery and time limits on oral examinations). Against that background, the judge found that the power to impose terms and directions under Rule 37.13 and Rule 1.05 provided jurisdiction. Those rules allow a presiding judge or associate judge, when deciding a motion, to grant relief with terms and give directions “as are just.” Given that the respondents had expressly asked for a timetable for discovery steps to move the matter along, the appellate judge held there was a sufficient nexus between the motion before the associate judge and her additional term limiting discovery motions in order to keep the case efficient and consistent with Rule 76’s objectives. On that basis, he concluded that the associate judge did have jurisdiction to make such an order, as a term ancillary to her decision on the particulars motion.

Procedural fairness and lack of notice

The appeal turned, instead, on procedural fairness. While the appellate judge accepted that jurisdiction existed in principle, he emphasized that significant procedural orders should not be made without giving the parties notice that such relief is being contemplated and an opportunity to be heard. Here, neither side had asked the associate judge to restrict discovery motions. The only relief formally sought by Aenos was an order compelling answers to its demand for particulars; the respondents sought, at most, a discovery timetable. There was no indication during the hearing that the associate judge was considering a leave requirement for future discovery motions, and counsel for both parties told the appellate judge they were taken by surprise when the decision issued. The appellate judge drew on Court of Appeal and Divisional Court authorities where judges had granted unrequested and significant remedies—such as vexatious litigant declarations or broad restrictions on steps in a proceeding—without proper notice or submissions, and where such orders were later set aside for lack of procedural fairness. Consistent with those cases, he found that Aenos should have had the chance to argue that this was the first and only motion in the action, that any delay was attributable in part to court scheduling rather than party conduct, and that it would be inappropriate to curtail its ability to bring legitimate discovery motions in the future. Likewise, the respondents could have argued that it was unfair for them to be subject to a restriction where they had brought no motions at all. Whether or not those arguments would have persuaded the associate judge, the parties were entitled to make them. The appellate judge concluded that, although the associate judge acted in the spirit of Rule 76 and out of a desire to control costs and delay, the absence of notice and a chance for submissions rendered the process unfair and undermined the validity of the discovery-motion restriction.

Outcome and monetary consequences

Having found that jurisdiction existed but that procedural fairness was lacking, the appellate judge allowed the appeal. He set aside paragraph 3 of the associate judge’s March 7, 2025 order, which was the portion requiring the parties to seek leave before bringing discovery motions. The rest of the associate judge’s decision—including the dismissal of the motion for particulars—was left undisturbed. The appeal was uncontested; the respondents did not oppose Aenos’ request to remove the discovery-related restriction. On costs, Aenos expressly did not seek any, and the court ordered that there would be no costs of the appeal. The decision addressed only this procedural issue and did not determine liability, damages, or any monetary remedy in the underlying lawyer’s negligence action. As a result, the successful party on the appeal was Aenos Food Services Inc., but no damages, costs, or other monetary amounts were awarded in its favour, and the total monetary amount ordered in this decision is zero, with the quantum of any eventual damages or costs in the negligence action not yet determined.
