The battle of the St. Lawrence involved a number of military incidents in the St. Lawrence River and the Gulf of St. Lawrence. This battle in Canadian waters began as a result of the presence of German submarines and their attacks on Allied ships in these inland waterways. Mostly between 1942 and 1944 German submarines attacked merchant vessels as well as Canadian warships escorting supply convoys.
The goal of these attacks was to weaken Great Britain by preventing the civilian population and the military from receiving the goods they needed to survive. Over a period of just two years, German submarines torpedoed some twenty ships in the waters of the Gulf of St. Lawrence and the St. Lawrence River.
As soon as the torpedoing began, Canadian authorities were forced to provide better protection at the mouth of the Gulf of St. Lawrence. Throughout the war, the Canadian military presence in Gaspé and the lower St. Lawrence River increased.

The battle of the St. Lawrence involved a number of military incidents in the St. Lawrence River and the Gulf of St. Lawrence. This battle in Canadian waters began as a result of the presence of German submarines and their attacks on Allied ships in these inland waterways. Mostly between 1942 and 1944 German submarines attacked merchant vessels as well as Canadian warships escorting supply convoys.
The goal of these attacks was to weaken Great Britain by preventing the civilian population and the military from receiving the goods they needed to survive. Over a period of just two years, German submarines torpedoed some twenty ships in the waters of the Gulf of St. Lawrence and the St. Lawrence River.
As soon as the torpedoing began, Canadian authorities were forced to provide better protection at the mouth of the Gulf of St. Lawrence. Throughout the war, the Canadian military presence in Gaspé and the lower St. Lawrence River increased.
The landscape was quickly changed by the establishment of military facilities to provide coastal defence and surveillance, to escort convoys, and to train and drill soldiers. More specifically, the military presence led to the development of a naval base in Gaspé, the construction of coastal batteries all along the shores of the St. Lawrence, a military airport at Mont-Joli, and coastal surveillance stations along the Gaspé Peninsula and the lower St. Lawrence River, not to mention many other facilities on the North Shore and the Gulf of St. Lawrence.
Although Canada was never directly attacked, daring military operations were conducted on Canadian territory. The Germans landed at least two spies in Canada, set up an automated weather station, and even attempted to rescue a German officer who had escaped from a Canadian prisoner of war camp. In addition to the Canadian merchant vessels that were torpedoed, the navy also lost three warships: HMCS Raccoon, HMCS Charlottetown and HMCS Bras d’Or. Many young sailors died.
