01
Holding and result
The appeal is dismissed because the prohibition remedy is unavailable where the challenged grounds are non‑jurisdictional; the Ontario Court of Justice is the proper forum to determine the applicability of MVDA provisions and any abuse of process by the prosecutor, and the application was an abuse of process with no prospect of success.

Party arguments
- Applicant
- Applicants sought prohibition to prevent provincial offence prosecution under the MVDA, arguing the prosecution was improper and raising issues they said justified supervisory intervention.
- Respondent
- Respondent argued the prohibition application was frivolous and an abuse of process because the issues raised were non‑jurisdictional and should be determined in the Ontario Court of Justice; respondent sought dismissal and costs.
05
Court’s reasoning
Legal principles
- 01
Common law supervisory jurisdiction of the Superior Court
Prohibition is a remedy to quash proceedings that are without jurisdiction
- 02
Common law and jurisprudential limits on supervisory remedies
Matters that are non‑jurisdictional should be resolved at trial in the appropriate lower court rather than by prerogative writ
- 03
Principles of prosecutorial discretion and procedure
Allegations of prosecutorial abuse of process ordinarily are raised and determined in the trial court where the prosecution is before the court
06
Ratio, limits and disposition
Ratio decidendi
The appeal is dismissed because the prohibition remedy is unavailable where the challenged grounds are non‑jurisdictional; the Ontario Court of Justice is the proper forum to determine the applicability of MVDA provisions and any abuse of process by the prosecutor, and the application was an abuse of process with no prospect of success.

COURT OF APPEAL FOR ONTARIO CITATION: Grey v. Ontario Motor Vehicle Industry Council, 2025 ONCA 768 DATE: 20251110 DOCKET: COA-25-CV-0192 Copeland, Wilson and Pomerance JJ.A.
BETWEEN Richard Grey and Tracy Grey Applicants/Responding Parties (Appellants) and Ontario Motor Vehicle Industry Council Respondent/Moving Party (Respondent) Walter Stasyshyn and Wade Morris, for the appellants Jordan Glick, for the respondent Heard and rendered orally: November 6, 2025 On appeal from the order of Justice Andra Pollak of the Superior Court of Justice, dated January 7, 2025,[1] with reasons reported at 2024 ONSC 6817.
REASONS FOR DECISION [1] The appellants brought an application for prohibition to prevent a provincial offence prosecution in the Ontario Court of Justice for offences under the Motor Vehicle Dealers Act, 2002, S.O. 2002, c. 30, Sched. B (the “MVDA”). The respondent, who is the prosecutor, brought a motion to dismiss the prohibition application, arguing that it was frivolous and an abuse of process of the court. The motion judge granted the motion and dismissed the application on the basis that it was an abuse of process and had no prospect of success. The appellants appeal from the motion judge’s order. [2] We agree with the motion judge’s conclusion. Prohibition is a remedy to address a lower court or tribunal proceeding without jurisdiction. None of the arguments raised by the appellants to challenge the prosecution are jurisdictional. The Ontario Court of Justice is the appropriate forum to determine whether the provisions of the MVDA under which the appellants are charged apply to the conduct alleged in the Information. Further, to the extent the appellants allege that the respondent as a prosecutor is engaging in an abuse of process, the Ontario Court of Justice is also the appropriate forum to raise that issue. [3] The appellants’ application for prohibition is an ill-conceived attempt to invoke the supervisory jurisdiction of the Superior Court for non-jurisdictional
issues which are properly decided at trial in the Ontario Court of Justice. The motion judge was correct in concluding that the prohibition application was an abuse of process and had no prospect of success. [4] The appellants’ contention that the motion judge’s reasons were inadequate is without merit. Read as a whole, the motion judge’s reasons are clear that she found that the application was an abuse of process and had no prospect of success because the grounds on which it was based were not jurisdictional. [5] The appeal is dismissed, with costs to the respondent in the agreed upon amount of $15,000 inclusive of disbursements and applicable taxes. “J. Copeland J.A.” “D.A. Wilson J.A.” “R. Pomerance J.A.” [1] The order is dated January 7, 2025, but indicates it was entered on January 15, 2025. The application judge’s endorsement dismissing the application is dated December 6, 2024.
