Judge to rule on criminal responsibility of man charged in Montreal triple slaying

Today, Justice Annie Émond will decide on Arthur Galarneau's criminal responsibility, this report was first published Jan. 22, 2026.
In December, Crown prosecutors and defence attorneys jointly submitted that Arthur Galarneau, 22, was not criminally responsible due to mental illness at the time.
Galarneau is charged in the March 2023 stabbing deaths of his mother Mylène Gingras, 53; father Richard Galarneau, 53; and grandmother Francine Gingras‑Boucher, 75 in Montreal.
Crown prosecutors seek a high‑risk offender designation to impose tighter restrictions on Galarneau, while the defence will contest this legal status.
Calls for solutions have grown since the triple homicide in Montreal, and national coverage by The Canadian Press has amplified public reaction.
