The Raid on Canso was an attack by French forces from Louisbourg on the British outpost Fort William Augustus at Canso, Nova Scotia shortly after war declarations opened King George's War. The French raid was intended to boost morale, secure Louisbourg's supply lines with the surrounding Acadian settlements, and deprive Britain of a base from which to attack Louisbourg. There were 50 English families in the settlement. While the settlement was utterly destroyed, the objective failed, since the British launched an attack on Louisbourg in 1745, using Canso as a staging area.

Major General John Bradstreet, born Jean-Baptiste Bradstreet was a British Army officer during King George's War, the French and Indian War, and Pontiac's War.
