Rising water levels in the St. Lawrence Seaway could cost the economy more than $1 billion, shippers and port operators say. A new study from the Chamber of Marine Commerce warns that opening the floodgates further at a dam in Cornwall, Ont., would wash away between $1 billion and $1.75 billion in revenue for businesses on both sides of the border. A board of control recently increased the flow at the Moses Saunders Dam — the only control point on the St. Lawrence Seaway, which includes the Great Lakes — to allow 10,400 cubic metres of water per second out of Lake Ontario.
Dozens of people in the Township of Whitewater Region have been forced from their homes as water levels on the Ottawa River peaked this weekend.
