The Sombra – Marine City (Bluewater) Ferry was a ferry service that crossed the St. Clair River, connecting Sombra, Ontario in Canada on the eastern bank with Marine City, Michigan in the United States on the western bank.
Occasionally during the winter months the ferry was temporarily unable to operate because of heavy ice buildup on one shore or the other.
On January 11, 2018, ice floe damage to the ferry's causeway caused the service to cease all operations.
[2][3] A proposed sale of the business fell through in 2019 as the US government was unwilling to commit to reopening the border station at Marine City.
A $6 million lawsuit against the Canadian government, filed in April 2019, remained pending at that time.
