THUNDER BAY - Two Jumbo Gardens-area residents escaped an early morning fire unharmed on Tuesday.
Firefighters were alerted to a structural fire in the 200 block of Carl Avenue just before 8 a.m..
In a release, Thunder Bay Fire Rescue said two occupants were alerted to a fire in the rear of the home, and escaped without sustaining injuries. A neighbour reported hearing screaming around that time.
Responding units observed a large amount of smoke and flames and called a second alarm. Five pumpers, a platoon chief, and aerial ladder unit were called to the scene and firefighters quickly knocked down the blaze.
The cause of the fire is yet to be determined.
