Woodbine Building Supply fire

On December 24, 2001, arsonists set fire to the Woodbine Building Supply Company building in Toronto, Ontario, Canada, causing an explosion and leading to one of the largest fires in the city's history. The arsonists were conspiring with John Magno, co-owner of the store, who desired to destroy the struggling business to collect a fraudulent insurance claim and clear the site for construction of a condominium development.
