On 10 Febuary, 1763, the Treaty of Paris was signed, officially ending the French and Indian War and Seven Years' War. In the document North American territory was redistributed between France, Spain, and Great Britian after the war. Britian gained all French territory east of the Mississippi and Spanish Florida, while the territories west of the Mississippi would become Spanish. The French could have given their islands instead of all of Canada but from a mercantile perspective, it made sense for the French to keep the small Caribbean island of Martinigue, Gaudelope, and St. Lucia due to their highly proifitable sugar industry. This is why the loss of Canada, which had been sapping their treasury, made sense for them to give the area to Britain. Also the Treaty of Fontainebleau had been signed before the Treaty of Paris, ceding French Lousiana to Spain.
