The Lancaster owned by the Canadian Warplane Heritage flies by my front window monthly during the summer, supporting various veterans' functions.
This link contains more info, including the CWH flying schedule for 2008:

I should also mention the Toronto Aerospace Museum, located at the former RCAF Downsview in north Toronto, which is restoring to display condition FM1104, the Lancaster which was mounted on a pedestal for thirty years at the foot of Strachan Street, exposed to the elements (of which we have a few) on the Toronto waterfront.
