Most criminal trials in Ontario are decided by a judge sitting alone. In many cases, a judge-alone trial is the strategically superior choice, offering precision, predictability, and a better forum for complex legal arguments.
When an accused person is charged with a serious criminal offence in Ontario, one of the first strategic decisions is the trial election: provincial court judge alone, Superior Court judge alone, or Superior Court judge and jury. The majority of trials in Ontario are heard by a judge sitting alone. Understanding why can help you and your lawyer make an informed decision about your own case.
How Judge-Alone Trials Work
A judge-alone trial follows the same evidentiary structure as a jury trial. The Crown calls its witnesses, who are cross-examined by defence counsel. The defence may call witnesses of its own. Both sides make closing submissions. The difference is that the judge plays the role of both fact-finder and legal arbiter. The judge assesses witness credibility, weighs the evidence, and decides whether the Crown has proven guilt beyond a reasonable doubt.
Because judges are trained legal professionals who have heard hundreds of criminal cases, they are generally better equipped than juries to make precise credibility assessments, apply the law correctly to complex facts, and write detailed reasons that can be reviewed on appeal. This predictability is one of the primary reasons defence lawyers often elect judge-alone.
When Judge-Alone Is the Right Election
Judge-alone trials are often preferred in cases involving complex legal arguments, including Charter applications to exclude evidence, cases where the facts are legally nuanced, and cases where sympathetic facts are unlikely to resonate emotionally with a lay jury. In drug cases where the primary issue is a Charter challenge to the search, for example, a judge-alone is typically the right forum. The judge can rule on the Charter application and then decide the underlying charge, giving both issues their proper legal treatment.
Similarly, in complex fraud cases where the evidence is largely documentary and the issues involve accounting, corporate law, or financial analysis, a judge-alone trial allows the trier of fact to engage with that complexity in a way that a lay jury may struggle with.
Provincial Court vs Superior Court Judge-Alone
An important distinction in Ontario is between provincial court judge-alone trials and Superior Court judge-alone trials. Summary conviction offences and some hybrid offences are tried in provincial court before a justice of the peace or provincial court judge. More serious indictable offences can be tried in Superior Court before a Superior Court judge alone. The election for Superior Court judge-alone triggers the right to a preliminary inquiry.
The choice between courts involves weighing the benefits of a Superior Court judge's enhanced experience with serious criminal matters against the more streamlined procedure available in provincial court. A criminal defence lawyer familiar with both courts will guide this decision.
You Can Sometimes Change Your Election
An election is not always locked in the moment it is made. The Criminal Code allows an accused to re-elect the mode of trial within defined time limits, and sometimes with the Crown's consent outside them. That flexibility matters, because a choice that looked right at first appearance can look different once disclosure is complete and the real issues have come into focus. A matter that seemed to call for a jury may turn out to hinge on a technical Charter argument better suited to a judge alone, or the reverse. Keeping the election under review as the case develops, rather than treating the first choice as final, is part of how the mode-of-trial decision is actually managed.
Written Reasons for Decision
One of the significant practical advantages of a judge-alone trial is that the judge must provide written reasons for the verdict. These reasons explain the basis for the decision and are subject to appellate review. If a judge convicted on a factual basis that the evidence did not support, or misapplied the law, the written reasons give defence counsel something concrete to bring to the Court of Appeal.
Section 536 of the Criminal Code governs the right to elect mode of trial for indictable offences in Canada.
