Site of the Soo Locks

Aerial View of Soo Locks
The city is the site of the Soo Locks, which lets ships travel between Lake Superior and the lower Great Lakes.

People come from around the world to view up close the ships passing through the locks. The largest ships are 1,000 feet (300 m) long by 105 feet (32 m) wide. These are domestic carriers (called lakers) that are too large to transit the Welland Canal around Niagara Falls and thus are land-locked. Foreign ships (termed salties) are smaller.
