The CAT car ferry between Rochester, NY and Toronto, Ontario was discontinued in January 2006 because of poor ridership. The Bay Ferries route from Bar Harbor in Maine to Yarmouth, Nova Scotia, also called the CAT, was discontinued in 2010 due to a lack of funding. (Bay Ferries does still run a New Brunswick to Nova Scotia ferry.)
