Several large-scale disasters occurred during the late 1940s and the 1950s that left permanent marks on Ottawa: A gas leak caused an explosion on Slater Street; a fire in the Byward Market destroyed an entire street block; an industrial accident at the National Research Council killed three people; and a military jet crashed into the Villa Saint – Louis Convent in Orleans.

Debris from Byward Market fire.

Title/Description: Debris from Byward Market fire. This was not the first time the Byward Market had suffered from fire. Previous serious blazes occurred in 1862 and 1874. However, the Market always bounced back from disaster and ensured that business continued.
