The two pilots were killed in the crash, along with 13 people in the building: 11 members of the Grey Nuns, a civilian servant, and the chaplain, a retired naval padre.

[1] At 10:37 p.m. May 15, 1956, two CF-100s took off from their base at RCAF Station Uplands (located south of Ottawa) on an exercise to practice interception techniques in identifying an unknown aircraft heading towards Montreal.

The plane was identified as a RCAF North Star flying from Resolute Bay to Dorval Airport.

The memorial was erected behind Villa St-Louis on May 13, 2009, by a group of Orléans veterans and members of the Sisters of Charity of Ottawa.

The ceremony was organized by three former members of the RCAF in co-operation with the Sisters of Charity who run the Residence Saint-Louis and the Orléans Legion.
