How long is the Canadian-U.S. border?
Zec Jaro
This trail offers a view of the border area Quebec-Maine which bounds the south of Zec Jaro. Lying about 8891 km, the Canada-U.S. border proves the longest on the planet. The border line is managed by a dedicated team appointed by the two governments to maintain visibility and accessibility are constant. Its layout from the Atlantic ocean to Pacific is marked by a series of numbered terminals entrenched in the soil. These terminals are obvious marks on the line between the two countries. Segment boundary between the province of Quebec and U.S. is 813 km long. The portion defining Zec Jaro south is about 24 km.
Height of Land Portage
According to the Canada/US International Boundary Commission, Ontario's boundary with the United States runs 2700 kilometers on water and only about one kilometer on land. The 80-rod Height of Land Portage is a significant part of the land border; the remainder is along two other portages, Watap Portage () a short distance to its east, and Swamp (or Monument) Portage () to the west in the BWCA and Quetico Provincial Park.
