A couple years ago, Greyhound discontinued the Discovery Pass that offered bus rides for a limited period on their North American network.
I also found about some RoutPass, a pass for riding on Quebec and Ontario buses for 7/14/21 days but apparently it is not valid any more since the end of 2012.
Is there a bus pass for (quasi) unlimited distance and time limited trips on buses in Eastern Canada? It would include Quebec and ideally the Maritimes (New Brunswick, Prince Edward Island and Nova Scotia) and even Ontario.
