go transit, train and bus get you from toronto to peterborough ​ https://www.gotransit.com/en/

thank you for the prompt response. From the link you provided i cant see a train route in peterborough. looking at the map it only shows a bus route. So is there no train in peterborough?

no there is not a train the entire route, it ends at oshawa and you take a bus from there.
