Union workers have ratified their labor contract with the St. Lawrence Seaway Management Corporation. The seven-day strike impacted 13 Canadian locks, but not the two U.S.-based locks. The entire St. Lawrence Seaway system was shut down, including the Port of Duluth. Multiple ships were loaded out of Duluth and unable to leave. There was also a growing number of inbound ships unable to enter this shipping route. Shipping activity has resumed.
