The respondent was charged with offences under the Ontario Water Resources Act.
During the trial, the respondent sought disclosure of a binder of documents held by a third party (the City).
The trial justice of the peace refused the application, stating the respondent must bring an O'Connor application.
The respondent then brought an application for prohibition to the Superior Court, which granted a stay of proceedings due to a breach of the right to a fair trial.
The Crown appealed.
The Court of Appeal allowed the appeal, holding that the trial court committed no jurisdictional error warranting mid-trial intervention by a superior court, and that a stay of proceedings was a disproportionate remedy.
