Police, firefighters and paramedics were called out to a fire in an apartment in a house (on Bruce Street) Saturday morning.
The paramedics provided aid to the lone female occupant of the apartment, who was later pronounced dead at the scene.
The victim is identified as 19 year old Taryn Hill of Thornbury.
The Fire Marshall's office says the fire is not suspicious.
A post mortem will be conducted this week to confirm the cause of death.
