Opération Casernes
In the early morning of 30 January 1964, a military wing of the Front de libération du Québec known as the Armée de libération du Québec broke into the Fusiliers Mont-Royal's barrack in an operation dubbed Opération Casernes and managed to steal numerous firearms.
At 7:30am on 30 January 1964, the ALQ broke into the barrack of Fusiliers Mont-Royal in Montreal. The ALQ militants killed the nightwatchman, killed a member of the Corps des Commissionnaires and captured 8 employees who they tied up. Afterwards, the ALQ militants began taking firearms and ammunition. By 9:00am, the ALQ had left with $20,000 in stolen firearms. This included 59 C1 rifles, 34 Sten guns, 4 Bren guns, 4 60-millimetre mortars, 3 Bazooka rocket launchers, 5 revolvers, 13,000 .22 long rifle rounds, 2,300 .303 British rounds, 2,000 7.62×51mm NATO rounds and multiple grenades.
Aftermath
The break-in caused soldiers to be deployed outside of all barracks in the Montreal metropolitan area the next day.
