- Montreal Olympic Stadium (1976) - one-ton concrete chunks fell down, bonds paid off in 2008.
- Velodrome - one of the most useful Olympic buildings, and best velodrome in the world, converted to zoo in 1989.
- Toronto Harbor Sq. "greenhouse" waterfront condos - grim walk in winter, but went from $50,000 each to $1 million.
- CN Tower - too rugged to tear down in heart of Toronto, savior was emerging need for a giant cell phone tower. :)
