The name of Toronto has a history distinct from that of the city itself. Originally, the term "Taronto" referred to a channel of water between Lake Simcoe and Lake Couchiching on maps as early as 1675 but in time the name passed southward, and was eventually applied to a new fort at the mouth of the Humber River. Fort Toronto was the first European settlement in the area, and lent its name to what became the city of Toronto.
