How far is it to the closest bus station where I can purchase Greyhound
tickets?
Also is there a Train station nearby?


The train station is quite close to your hotel, but unless your destination
is on the main corridors you are probably better off taking the bus.
Canadian rail service is infrequent and usually runs late. Bus service is
much more frequent and tends to run on time.
