The 905 Derby is a soccer rivalry between Canadian Premier League clubs, Forge FC and Inter Toronto FC, both based in Southern Ontario. The rivalry gets the "905" nickname from the 905 area code, which encompasses both Hamilton and York Region. Forge and Inter Toronto were the only Ontario-based teams in the inaugural season of the league and remain the two closest in proximity, with less than 65 kilometres (40 mi) separating their home stadiums.
