Yeah, now we're talking! I wish VIA could restart that service as well, they could but it's owned by a US company. It would be much faster than the Ocean.
It looks like Cyr already operates bus service up to Caribou, I hope they can get it back up to Van Buren, maybe even Edmundston across the border. It was apparently taken over from B&A in 1984, but I have no idea what their fleet has.
Used to ride the thru GL-BAR pool bus years ago from the Port Authority all the way to Fort Kent, Me., at the north end of US 1. From Madawaska, we went into Edmundston, made a stop there, and back to Madawaska enroute. A customs officer rode back and forth from the border checkpoint, and thru passengers weren't even bothered.
I doubt that would occur nowadays...
Back then, (late 60's), Greyhound ran two all year locals on US 1 and 2 to the Calais/St. Stephen border. In the summer, they ran an express up Maine 9 that continued in pool service all the way to Halifax operated by SMT Eastern Limited and Acadian Lines.
I agree that it would be nice to see the Atlantic Limited return and restore service to Saint John, but considering the finances of VIA, not likely...
