From the CBC:

A man has been arrested after a bus was stolen from a TTC garage in Scarborough, driven to Whitby, and abandoned.

The man, 33, now in custody in Whitby, has been charged with possession of stolen property.

Durham Regional Police said they located the bus at the corner of Bonacord Avenue and Cochrane Street in Whitby at about 5:15 a.m. It was taken from the TTC’s Birchmount garage.

Anyway, even though apparently public transit busses don’t need keys to start, please refrain from stealing them.
