O. Reg. 310/26 and Family Rule 1.4: The Shifting Framework of Summary Dismissals

In ordinary adversarial litigation, a party seeking to strike or dismiss another party’s claim bears the burden of establishing the grounds for that relief. The party who commenced the proceeding is not ordinarily required to justify its continued existence merely because an opposing party alleges that it is defective or abusive.

Ontario’s summary dismissal procedures, however, operate under a materially different framework.

Under Civil Rule 2.1, and now Family Rule 1.4, a preliminary judicial assessment can trigger an automatic stay before any final determination is made that the proceeding is actually frivolous or vexatious or otherwise an abuse of process. Once the prescribed administrative notice is issued, the litigant who commenced the proceeding faces a strictly compressed opportunity to explain why the case should continue.

While these rules do not expressly state that the ultimate legal burden of proving an abuse of process has been transferred, their practical operation places a significant burden of preserving the proceeding onto the litigant whose case has already been suspended.

This is the administrative reverse onus: the litigant must justify the continuation of their case after the machinery of summary dismissal has already frozen the proceeding.

From Civil Rule 2.1 to Family Rule 1.4

Civil Rule 2.1 provided the original architecture. Following a preliminary judicial screening, the registrar issues a notice in Form 2.1B. Under Rule 2.1.01(7), that notice automatically stays the proceeding and prohibits any further procedural steps except those expressly permitted by the rule or authorized by the court. The responding party is granted a limited opportunity to file a written submission.

Through O. Reg. 310/26, the Family Rules Committee has now imported this architecture into family litigation.

Family Rule 1.4 is formally symmetrical, but its practical consequences fall primarily on the litigant seeking to advance the case. Although either party may request screening under Rule 1.4, in most cases the request would be expected to come from the party opposing the proceeding, rather than the party who commenced it. If a compliant submission is not filed, the procedure permits the court to issue a final dismissal without further notice.

Rule 1.4 introduces an additional mechanism: an opposing party may initiate this summary dismissal process by serving and filing a Form 1.4 request, without the need to bring a conventional, affidavit-supported motion.

Filing the request does not itself stay the case. The court must first determine whether a summary dismissal may be appropriate and direct the clerk to issue notice in Form 1.4A. Once that notice is issued, however, Rule 1.4(6) automatically stays the entire proceeding. No party may take further steps except those permitted by Rule 1.4 or authorized by the court.

The party who commenced the case is then granted exactly 15 days to file a written response of no more than 10 pages, unless the court orders otherwise. If the 15-day deadline expires without a compliant response, the court may make the contemplated order without further notice to the parties.

The structural reality is clear: the stay precedes the final determination. The obligation to defend the continuation of the case follows the suspension of rights.

As a result, a family litigant may find their entire proceeding suspended before the court has examined any of the underlying substantive issues—whether parenting, support, property, or family violence—through an ordinary evidentiary process. The significance is not only that an opposing party can initiate this process without affidavit evidence; it is that once the preliminary threshold is crossed, the stay descends automatically, without a separate judicial determination that an interim stay is actually justified.

The Statutory Benchmark: Section 137.1 of the Courts of Justice Act

The Legislature has demonstrated how to establish a lawful, express burden-shifting framework for summary dismissals.

Under section 137.1 of the Courts of Justice Act, the anti-SLAPP regime establishes defined procedural stages. In 1704604 Ontario Ltd. v. Pointes Protection Association, 2020 SCC 22, the Supreme Court of Canada explained that the moving party must first satisfy a statutory threshold demonstrating the expression relates to a matter of public interest. Only after the moving party meets that threshold does the burden shift to the responding plaintiff to satisfy the requirements of section 137.1(4) to avoid dismissal.

That allocation of burden is expressly prescribed by primary legislation.

Family Rule 1.4 contains no comparable statutory provision transferring the ultimate legal burden of proof regarding an abuse of process. Instead, its automatic stay and compressed 15-day response window create a practical burden: the party whose case has been suspended must address the court’s preliminary concerns in order to avoid permanent dismissal.

This distinction raises a fundamental question about the difference between a substantive burden expressly allocated by the Legislature and a practical burden created through delegated procedural rules.

The Limits of Delegated Authority

Section 66 of the Courts of Justice Act grants the Civil Rules Committee the delegated authority to regulate “practice and procedure.” Section 68 establishes the corresponding authority of the Family Rules Committee, incorporating specified powers under section 66.

While section 66(2)(d) permits rules concerning the disposition of proceedings without a hearing, that authority must be distinguished from the separate question of whether a Rules Committee possesses the statutory jurisdiction to create a procedural framework that effectively places the burden of preserving a proceeding onto the litigant before an abuse of process has actually been established.

In Snell v. Farrell, [1990] 2 S.C.R. 311, the Supreme Court of Canada distinguished the ultimate legal burden of proof from the practical or tactical burdens that arise during litigation. That distinction is relevant here.

Family Rule 1.4 does not explicitly declare that the party who commenced the case must prove the absence of abuse. However, once a Form 1.4A notice activates the automatic stay, that party is structurally required to confront the court’s preliminary concerns while ordinary procedural steps remain prohibited. The formal legal burden and the practical burden of preserving the proceeding are thereby misaligned.

The jurisdictional question is whether this practical reversal—imposed through an automatic stay and a short response window—remains within the rule-making authority delegated by the Legislature.

The delegated authority to provide a mechanism for summary disposition does not necessarily grant a Rules Committee the jurisdiction to place the burden of preserving an already-suspended family case onto a litigant before a final determination of abuse has occurred. Family Rule 1.4 brings that jurisdictional question directly into the family law arena.

This administrative reverse onus is not merely a theoretical dispute over evidentiary thresholds. It shapes the practical allocation of procedural rights at the moment a family litigant seeks access to a judicial determination.
