There's been more shipping activity on the Great Lakes so far this season compared to last year.

The President and CEO of the Windsor Port Authority says they have seen a 10 per cent increase in shipments.

David Cree says the Windsor port is handling more salt, petroleum, steel and grain.

Volume of stones was down, but Cree thinks that will change next year when work is expected to pick-up for the Gordie Howe International Bridge.

Meanwhile, the St. Lawrence Seaway reports a 20 per cent increase in shipments.

The seaway management says the increased volume is a reflection of economic conditions.
