The appellant appealed his dangerous offender designation imposed by the trial judge on January 15, 2013.

The Court of Appeal upheld the designation, finding that the trial judge properly applied the test under s. 753 of the Criminal Code.

The trial judge found that the appellant met the criteria for dangerous offender status based on a pattern of repetitive behaviour showing a failure to restrain his conduct, and that this failure created a likelihood of causing injury to others.

The trial judge also found a pattern of persistent aggressive behaviour demonstrating substantial indifference to the foreseeable consequences of his actions.

The trial judge exercised her discretion to reject the long-term offender designation, concluding that the public threat could not be reduced to an acceptable level through a determinate sentence or long-term supervision order.

The Court of Appeal found the trial judge's findings were open to her on the record and entitled to deference, and her determination was reasonable.

The appellant appealed his conviction for assault causing bodily harm and sought leave to appeal his sentence.

The conviction arose from an assault on a fellow inmate at a detention centre.

The Crown's case relied on surveillance video and victim testimony.

The appellant was identified in the video as approaching the washroom area where the assault occurred and appearing to deliver a knee strike.

The trial judge instructed the jury that the appellant could be found guilty as either a joint principal or an aider.

The Court of Appeal found sufficient evidentiary basis for the jury instructions and dismissed the conviction appeal.

On sentencing, the appellant invoked the parity principle, comparing his 20-month sentence (reduced to 191 days after pre-disposition custody credit) to a co-accused's 18-month sentence.

The Court found the sentences were not comparable due to differences in culpability, criminal records, and mitigating factors, and dismissed the sentence appeal.

The Crown applied for an assessment of the defendant's fitness to stand trial pursuant to section 672.11(a) of the Criminal Code.

The defendant, a 26-year-old deaf and non-speaking individual from Nigeria who communicates only through family sign language and is illiterate, was charged with sexual assault and sexual interference.

The defence opposed the application, arguing that deafness is not a mental disorder and that the defendant possessed rudimentary understanding of fitness concepts.

The court found reasonable grounds to doubt the defendant's fitness based on expert evidence establishing mental retardation as a mental disorder, despite the defendant's basic understanding of rules and punishment.

The court granted the Crown's application for a fitness assessment, distinguishing its conclusion from a prior ruling by Justice Schneider based on the different evidence presented.

The accused were jointly tried for offences arising from a robbery at a mall cell phone store during which the victim was shot.

The central issue was whether the victim produced a firearm and accidentally shot himself during a struggle, as claimed by the accused, or whether one of the accused produced and discharged the weapon.

The court rejected the accused’s testimony as implausible and inconsistent with surveillance evidence and witness testimony, finding that one accused possessed and fired the handgun to facilitate the robbery while the other knowingly participated.

The principal offender was convicted of robbery while armed, aggravated assault, discharging a firearm with intent, and firearm possession offences.

The co‑accused was convicted of robbery while armed and firearm possession offences but acquitted of the aggravated assault and firearm discharge counts due to reasonable doubt about foreseeability.
