The Treaty of Paris 1763 marked the end of the French and Indian War (also known as the Seven Years' War) and included several key provisions regarding territory. One of the main outcomes was the transfer of all French territories in North America to Great Britain. Specifically, France ceded Canada and all its territories east of the Mississippi River to Britain. Additionally, France ceded Louisiana to Spain as compensation for Spain's loss of Florida to Britain.
So, while the statement "all French land" is not entirely accurate, the main provision did involve significant territorial changes favoring British interests.
