A sister city of Ann Arbor, Peterborough is about 6.5 hours from Ann Arbor by car, and 1.5 hours east and north of Toronto.

Portions of the film Jumper were filmed here, with Peterborough standing in for Ann Arbor in some scenes.

The Arborough Games were an exchange between the two cities around sports programs, which was active circa 1991.

Like Ann Arbor, Peterborough has fairy doors.
