The province’s Special Investigations Unit is investigating the circumstances surrounding the death of a 41-year-old man this weekend in Thunder Bay.

Preliminary information suggests the following:
  • On the evening of October 10, 2026, Thunder Bay Police Service officers were dispatched to an apartment building in the area of May Street South and Donald Street East for a reported disturbance.
  • Upon arrival at an apartment unit, officers became aware that a man inside the unit was suffering from a crisis. When officers were told the man was having difficulty breathing, they entered the unit and commenced first aid. Fire and EMS arrived shortly after.
  • The man was transported to hospital where he was pronounced deceased.

Two investigators and one forensic investigator have been assigned to the case.
