From the Wikipedia article

On April 25, 1944, a Royal Air Force Liberator B Mark VI en route to Britain via Gander, Newfoundland crashed into the Griffintown neighborhood in downtown Montreal, Quebec minutes after taking off from Dorval Airport. The five-member crew and ten civilians on the ground were killed, and a large fire destroyed at least 10 homes.

Crash

Just after takeoff at 10:24 AM, the crew reported problems. The plane cleared Mount Royal but started to lose altitude over downtown Montreal. It passed in front of the Sun Life Building and narrowly missed the tower of Windsor Station and the chimney of the Dow Brewery. At 10:30, it struck residential buildings near the corner of Shannon Street and Ottawa Street. There was an explosion, and fire immediately broke out, spread by the 9,000 litres of fuel. Firefighters took hours to contain the blaze. In all, 10 to 15 homes were destroyed in the crash and subsequent fire.

Investigation and cause

Cause of the crash

The Ministry of Defense report cited structural failure of the tail section as the cause of the crash. Witnesses in the Sun Life Building described seeing part of the tail detached as it flew at low altitude apparently trying to reach the river to ditch.
