3rd Canadian Infantry Division

The 3rd Canadian Infantry Division with the 2nd Canadian Armoured Brigade under command landed in two brigade groups,the 7th Canadian Infantry Brigade and the 8th Canadian Infantry Brigade, Each Brigade had three Infantry Battalions and an armoured regiment in support, 2 artillery field regiments, combat engineer companies and extra units from the 79th Armoured Division. The Fort Garry Horse tanks (10th Armoured Regiment) supported the 7th brigade landing on the left and the 1st Hussars tanks (6th Armoured Regiment) supported the landing on the right.

The 9th Canadian Infantry Brigade was kept in reserve and landed later that day and advanced through the lead brigades. The Sherbrooke Fusiliers tanks (27th Armoured Regiment) provided tank support.

The initial assault was carried out by:

North Shore Regiment on the left at St. Aubin (Nan Red beach)

Queen's Own Rifles in the centre at Bernières (Nan White beach)

Regina Rifles at Courseulles (Nan Green beach)

Royal Winnipeg Rifles on the western edge of Courseulles (Mike Red and Mike Green beaches)

In the first hour of the assault on Juno Beach, the Canadian forces suffered approximately 50% casualty rates, comparable to those suffered by the Americans at Omaha Beach. Once the Canadians cleared the seawall (about an hour after leaving the transports) they started to advance quickly inland and had a much easier time subduing the German defences than the Americans at Omaha had. By noon, the entire 3rd Canadian Division was ashore and leading elements had pushed several kilometres inland to seize bridges over the Seulles River. By 6:00 pm they had captured the town of Saint-Aubin-sur-Mer. A 1st Hussars armoured troop reached its objective along with men of The Queen's Own Rifles of Canada before nightfall, when both units moved 15 km inland and crossed the Caen-Bayeux highway. However, this troop was forced to pull back because they had passed the supporting infantry. By the end of D-Day the 3rd Canadian Division had penetrated farther into France than any other Allied force, though counter-attacks by elements of two German armoured divisions would stop any further movement for several weeks.

None of the assault divisions, including 3rd Canadian Division, had managed to secure their D-Day objectives, which lay inland, although the Canadians came closer than any other Allied formation.

By the end of the next day, the Canadian forces had linked up with the British forces that had landed at Sword Beach.
