A Canadian defence historian worries that eviction of Toronto’s Air and Space Museum from its Downsview location threatens the country’s aviation heritage. On Sept. 20, Downsview Park, the museum’s landlord, delivered an eviction letter to museum volunteers, saying the museum has six months to pack up and leave.

After nearly 30 years of faithful service in outer space, the Canadarm is set to return home when NASA’s space shuttle program concludes with the final shuttle blast-off later this month. The decision that remains, however, is where the one arm retiring home to Canada will actually reside. At least two Canadian museums want it.
