Rule 21.01 vs. Rule 2.1.01: “A Judge” vs. “The Court”

The use of summary proceedings under Rule 2.1 in Ontario civil procedure rests on a textual difference between traditional motion practice and the procedure introduced in 2014. Tracing the rule from its implementation to its application shows how a change in wording affected the allocation of authority between single judges and panels.

Under traditional civil procedure, striking a proceeding for an “abuse of process” required a showing of actual vexatious misconduct—such as harassing litigation, bad faith, or fundamentally abusive behaviour. When Rule 2.1 was drafted, the rule-makers used “the court” rather than the more specific “a judge.”

A comparison of the governing texts shows the difference:

• Rule 21.01 (traditional motion practice): A party may move before a judge, and the judge may make an order or grant judgment.
• Rule 2.1.01 (summary process): The court may make an order staying or dismissing a proceeding that appears on its face to be frivolous or vexatious or otherwise an abuse of the process of the court.

Under the Courts of Justice Act, the terms are not interchangeable:

• “A judge” (s. 7(2)): Refers to a single judge, whose jurisdiction on an appeal is limited to motions, subject to the exceptions in s. 7(3).
• “The court” (s. 7(1)): Refers to a panel of not fewer than three judges when hearing and determining a proceeding in the Court of Appeal.

The difference in wording leaves open a question of how a single judge exercising Rule 2.1 authority relates to the panel requirement in s. 7(1). When a single appellate judge dismisses an appeal under Rule 2.1, the disposition is final. When a panel uses the Form 2.1B process, the determination proceeds on written submissions rather than the fuller process associated with a motion to quash. No reported appellate decision has fully addressed how these uses of Rule 2.1 align with the panel requirements of s. 7(1).

Redefining Abuse of Process

Because Rule 2.1 uses “the court” rather than “a judge,” decisions interpreting the rule have treated a clear lack of jurisdiction as sufficient to constitute an abuse of process. Chowdhury v. Unity Health Toronto, 2025 ONCA 90, is one such decision. Under that approach, a procedural error or jurisdictional defect can support a Rule 2.1 dismissal without a separate finding of bad faith or harassment.

The result is that the phrase “abuse of process” is applied to a broader range of circumstances than under traditional Rule 21 practice; a procedural error, a routing miscalculation, or a technical jurisdictional defect is arbitrarily equated with bad faith. Once a court finds that a proceeding appears on its face to be frivolous, vexatious, or an abuse of process, the Form 2.1B process can result in dismissal. Because these determinations are made on written submissions and are infrequently pursued to the Supreme Court of Canada, the practical effect is that single judges and panels operate with limited subsequent review of the classification.

The El-Guindy Decision and Jurisdictional Limits

The application of Rule 2.1 in an appellate context is addressed in El-Guindy v. Interrent Holdings Manager LP, 2026 ONSC 3205. The decision discusses the limits of inherent jurisdiction and the use of Rule 2.1 by a single judge.

Under Canadian constitutional law:

• The Superior Court of Justice, as a trial court of general jurisdiction, possesses inherent jurisdiction unless removed by statute (Constitution Act, 1867, s. 96).
• The Divisional Court is a statutory court established under the Courts of Justice Act. When sitting as the Divisional Court, judges exercise appellate or judicial-review jurisdiction and do not possess the inherent jurisdiction of the Superior Court sitting as a trial court.
• The Court of Appeal for Ontario is also a statutory court and does not possess inherent trial-level jurisdiction (Kourtessis v. M.N.R., [1993] 2 S.C.R. 53).

Any implied power of a statutory court to control its process must be connected to its statutory jurisdiction over the proceeding. Once a court determines that a proceeding does not engage its jurisdiction, the basis for an implied power to dismiss under Rule 2.1 is limited. A procedural rule cannot confer jurisdiction that the enabling statute does not grant.

From El-Guindy v. Interrent Holdings Manager LP, 2026 ONSC 3205:

[3] While Mr. El-Guindy is correct that the Divisional Court has no inherent jurisdiction, a single judge has jurisdiction pursuant to r. 2.1.01 of the Rules of Civil Procedure, R.R.O. 1990, Reg. 194, to dismiss a proceeding on the basis that it appears on its face to be frivolous, vexatious or an abuse of the process of the court. While McNeil J. did not avert to r. 2.1.02 in her reasons, it is clear that she was of the view that the contempt motion was frivolous, vexatious and an abuse of process. Her conclusion in this regard was undoubtedly correct, as a finding of contempt against a Landlord and Tenant Board member was precluded by the principle of adjudicative and judicial immunity: Stepanova v. Ontario (Human Rights Tribunal), 2017 ONSC 2386 (Div. Ct.), at para. 23. We are satisfied that McNeil J. had the jurisdiction to make the order that she did.

In paragraph 3 of the El-Guindy endorsement, the court stated that while the Divisional Court has no inherent jurisdiction, a single judge has jurisdiction under r. 2.1.01 to dismiss a proceeding. That statement places a final disposition in the hands of a single judge of a statutory appellate court. It therefore illustrates the same panel-composition question that arises under s. 7(1) of the Courts of Justice Act at the Court of Appeal, where a proceeding must be heard by not fewer than three judges. The decision shows the practical use of Rule 2.1 to authorize a final disposition by a single judge in an appellate setting, and the continuing tension with the panel requirements that govern statutory appellate courts.

The Bypass of Section 7(1)

The Rules of Civil Procedure are delegated, subordinate legislation. The Courts of Justice Act is primary statutory law. A subordinate regulation cannot implicitly repeal, amend, or bypass the mandatory requirements of its parent statute. Therefore, by permitting a single judge to use Rule 2.1 to produce a final dismissal—a power they lack under Rule 21 and under s. 7(1)—the court allows a subordinate procedural rule to achieve a result the primary statute does not authorize. Section 7(1) of the Courts of Justice Act requires three appellate judges to finally dispose of an appeal. The legislature did not create an exception for cases a single judge considers weak, jurisdictionally defective, or an abuse of process.

A formal Rule 21 motion to strike imposes an exceptionally high procedural and evidentiary burden on institutional respondents. Governed by the Supreme Court’s strict “plain and obvious” test in Hunt v. Carey, [1990] 2 S.C.R. 959, a claim can only be dismissed if it has zero chance of success, requiring the court to presume every pleaded fact is unequivocally true. Because respondents are barred from introducing affidavits, disputing evidence, or attacking the litigant's credibility, they must argue their case purely on the law. This rigorous legal threshold demands significant procedural effort and expense, forcing respondents to draft formal notices and comprehensive factums, defend their position in open court, and risk adverse cost awards if they fail.

The current appellate use of Rule 2.1 functions as a de facto Rule 21 motion. Institutional respondents obtain the ultimate benefit of a Rule 21 motion to strike—a final dismissal with prejudice—while avoiding the procedural costs that accompany it. There is no three-judge panel, no presumption that the facts pleaded are true, no oral hearing, and no opportunity to amend. The respondent effectively pleads Rule 21 defects; the court applies a Rule 2.1 label so a single judge can dispose of the matter in chambers.

A further consequence is that Rule 2.1 shifts the inquiry from the legal question to the person. Once the process is framed as an alleged abuse of process or as vexatious conduct, the attention falls on the moving party’s character, history, and supposed intent. The jurisdictional or substantive defect that would ordinarily be tested on a proper motion to quash or a Rule 21 motion becomes secondary. The person is put on the defensive for being “vexatious” or for abusing process, while the underlying question—whether the court has jurisdiction, or whether the pleading discloses a reasonable cause of action—is never examined under the ordinary rules that govern those issues.

This is distinct from a motion to quash or a Rule 21 motion. Those processes address the claim or the appeal on its legal merits. Rule 2.1, by design, authorizes a summary dismissal on the basis that the proceeding is an abuse of process. When that mechanism is used for pure jurisdictional defects or for ordinary Rule 21-type deficiencies, it converts a question of law into a personal characterization. The institutional respondent does not have to meet the ordinary burden of showing that the appeal or motion is legally deficient under the governing statute or rule. Instead, the court is invited to conclude that the person bringing it is abusing the process.

Taken together, the practice allows a subordinate rule to produce a final appellate disposition that s. 7(1) reserves to a panel, while simultaneously reframing the dispute as one about the litigant rather than the law. Neither Simpson nor Collins authorized that result. A clear lack of jurisdiction remains a matter for a motion to quash. A pleading defect remains a matter for Rule 21. Rule 2.1 does not create an intermediate path that achieves the same end without the process the statute and the rules otherwise require.
