Portage Canal The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway. For a time, it completed a route from the north Atlantic Ocean, through the St. Lawrence Seaway and down the Mississippi River to the Gulf of Mexico, and back to the Atlantic.
Toronto Carrying-Place Trail The Toronto Carrying-Place Trail, also known as the Humber Portage and the Toronto Passage, was a major portage route in Ontario, Canada, linking Lake Ontario with Lake Simcoe and the northern Great Lakes. The name comes from the Mohawk term "toron-ten", meaning "the place where the trees grow over the water", an important landmark on Lake Simcoe through which the trail passed.
