In a multi‑accused murder trial, the Crown sought to introduce a PowerPoint presentation prepared by an Ontario Provincial Police analyst summarizing extensive cell phone records already entered in evidence.

Defence counsel objected, arguing the presentation was redundant, prejudicial, and effectively allowed the Crown to present its theory of the case twice.

The court held that the PowerPoint itself was not evidence but an illustrative aid reorganizing evidence already admitted.

Although useful and reliable, its probative value was outweighed by prejudice arising from duplication, significant trial time, and the unfair advantage of allowing the Crown to present its theory through a witness before closing submissions.

The court excluded the presentation from evidence but permitted the Crown to use it in closing argument and ordered the Crown to disclose the presentation to defence counsel in editable PowerPoint format.

During a joint first‑degree murder trial, concerns arose that the spouse of a juror had attended court proceedings and communicated limited information about the case to the juror via text messages and made comments in the courthouse hallway supportive of a police witness.

Following two judicial inquiries, the accused sought either a mistrial or the discharge of the juror on the basis of juror contamination and reasonable apprehension of bias.

The court held that although the spouse’s conduct demonstrated poor judgment, there was no evidence that the juror discussed the case with the spouse or was influenced by her views.

Applying the presumption of juror impartiality and the reasonable apprehension of bias test, the court found no basis to conclude the juror could not remain independent and impartial.

The mistrial application and request to discharge the juror were denied, though the spouse was excluded from further attendance at the trial.
