Roller Derby league in Hamilton, Ontario, Canada.

Established in January 2006, The Hammer City Roller Girls (HCRG) is an all female, not-for-profit, skater operated, flat track roller derby league based in Hamilton, Ontario. For the 2011 season, HCRG re-aligned its home team structure to focus its efforts on inter-league play. The league is now comprised of the WFTDA sanctioned/charter Hammer City Eh! Team and the Hammer City Harlots regional team, both of whom compete against other cities in Canada and the US.
