The Yarmouth to Maine ferry service is back. The province has signed a deal with STM Quest to re-establish the link starting May 1, 2014. The service will be known as Nova Star Cruises. Economic and Rural Development and Tourism Minister Michel Samson made the announcement Tuesday afternoon in Halifax.The province has committed up to $21-million of financial support over seven years, including $10.5-million in start-up costs. Both sides agreed to make amendments to the letter of offer announced in September including more auditing rights for the province. There are still challenges for the Yarmouth to Maine ferry to start next May including having border services in both ports, and getting all licenses and permits needed to operate a ferry service.
