The regiment was designated the 5th Motorcycle Regiment (BCD), and later an armoured car unit. Finally made into an armoured regiment, the 9th Armoured Regiment (BCD), they were deployed to Italy as part of the 5th Armoured Brigade, 5th Canadian (Armoured) Division. The regiment saw heavy action in the Liri Valley, were the first unit to break through the Gustav Line in Italy, 1944, and helped smash the Gothic Line, holding Point 204 right in the centre of the line. Part of the "D-Day Dodgers", a term used by soldiers fighting in Italy after D-Day, they continued to fight until orders were given to move the regiment to the northwest Europe area. They served with distinction until the end of the war, at which point the regiment was demobilized and returned to Militia service.
