# LaSalle Heights disaster

The LaSalle Heights disaster occurred in the early morning of March 1, 1965, in the city of LaSalle, Quebec when a gas line explosion destroyed a number of low-cost housing units. In all, 28 people were killed, 39 were injured and 200 left homeless. Most of the casualties were women and children.

## LaSalle Heights

LaSalle Heights is a suburban residential block of low-income rental units located at the corner of rue Bergevin and rue Jean Milot in LaSalle, Quebec, on the Island of Montreal. It was constructed by LaSalle Heights Inc. in 1955 and 1956 at a cost of $5,300,000. In 1955 construction was announced and the site was expected to consist of 678 units (54 three-bedroom houses in rows, 422 three-bedroom apartments, 136 two-bedroom apartments, 50 one-bedroom apartments, and 16 bachelor apartments). Rents ranged from $30 a month to $57 a month and were available to families whose monthly income ranged between four and six times their rent.
The block consisted of 25 identical U-shaped buildings, each housing 36 units of various sizes.

## Explosion

At approximately 8:05 am a six-inch (150 mm) fissure emerged in a natural gas supply line in the cellar of 367 rue Bergevin, destroying units in it along with those in buildings 365, 363 and 361. Approximately 36 units were affected. The explosion left a twenty-foot-deep (6.1 m) crater where the three-story apartment building had stood. During subsequent inquiries on the incident, metallurgists André Hone and William Williams concluded that a cracked pipe, most likely damaged during transportation or installation, was the cause of the explosion.

## Casualties

At 10:00 pm on the evening of the explosion, Coroner Marcel Trahan released some names of the known dead. On March 3 a more complete list was released. At the time, four people were still missing and one deceased victim was unidentified.
