Saint John Transit is the largest transit system in New Brunswick in both area coverage and ridership. Bus service is provided by Saint John Transit (Greater Saint John Area) and Maritime Bus (Inter-city). Acadian Lines used to operate regular inter-city bus services between New Brunswick, Prince Edward Island, Nova Scotia, Bangor, as well as Rivière-du-Loup, Quebec (connecting with Orléans Express). Maritime Bus has since replaced Acadian Lines as the regional bus service.
