It's a building residents describe and quiet and safe, but Saturday it was surrounded by police cars and ambulances.
A woman in her 20s died after being shot in the head. She was hit inside an apartment on the fourth floor at 12 St. Dennis Drive near Don Mills and Eglinton at around 2 p.m.
A man, also believed to be in his 20s, was taken to 54 Division for questioning. It isn't clear what relationship he has to the victim.
Toronto EMS say they were told the shooting was accidental but that hasn't been confirmed by Toronto Police.
Police have not relased the victim's identity yet, saying her next of kin is being notified.
