Lack of ice on Great Lakes and rivers is helpful to shipping but may have environmental impacts

A mild winter has meant not very much ice has formed on the Great Lakes and Lake St. Clair. "This year is an extraordinary year," said Steve Salmons, president and CEO of the Windsor Port Authority. Salmons says the lack of ice means ships have easier time of navigating but it doesn't mean a higher volume of goods moves because most ships are taken out of service for winter maintenance and the locks close seasonally anyway.
