The London Ice House was an arena in London, Ontario, Canada. It was originally built in 1963 and was home to the London Knights ice hockey team from 1965 to 2002. The design was influenced by the first level of the Boston Garden, and had a capacity of approximately 5,000. The arena was originally named Treasure Island Gardens as the building was a part of the Treasure Island Plaza mall complex located in south London. For a time, the arena also included a second ice pad.
