Sara - I would have to believe that it is every bit of that! Not sure where you are considering MP-0, but using Google Maps (Bike Mode) and Canalside in Buffalo as the start, touring on the Canal trail shows 70 miles.
Depending on your need to start in Buffalo (and Buffalo is a fun place), the first part of the tour rides along the Niagara River on the Seaway Trail up to the Tonawanda's (City of and North Tonawanda). This is where the Erie Canal actually begins. Starting here saves you 16 miles... but you have to figure logistics with how you are traveling into Buffalo to get out there.
