Which French island colony was restored to France by the 1763 Treaty of Paris?

The French island colony restored to France by the 1763 Treaty of Paris was Saint Pierre and Miquelon.

The islands, off the coast of Newfoundland, were returned to France after Britain’s victory in the Seven Years’ War. The treaty, signed on February 10, 1763, transferred most of France’s mainland North American possessions to Britain but preserved a small French presence in the North Atlantic. Saint Pierre and Miquelon served as a shelter and base for French fishermen using the Newfoundland fishery.

This settlement did not restore Canada, Cape Breton Island, or Newfoundland to France. Britain retained those territories, while France kept fishing rights off Newfoundland and the two small islands. Saint Pierre and Miquelon had previously been ceded to Britain under the 1713 Treaty of Utrecht, making their return in 1763 a restoration rather than a new acquisition. The islands remain French territory today, though they were occupied by Britain during several later conflicts.
