The City of Toronto is having difficulty enforcing a six-year-old helmet policy, which has come under criticism in the city's south end. “We have had difficulties with Jutta Mason and the group that she represents,” said City of Toronto supervisor of active living Kevin Mercer. “They don't like helmets and I'm not really sure why.” Mason, an ardent public space activist, is a founding member of the Friends of Dufferin Grove Park. Though a three-phase helmet policy began in 2002, the issue came to the forefront when a ten-year-old child was killed while playing shinny hockey without a helmet in 2006 in Guelph. This season, City officials have made a heavy push for compliance at all outdoor rinks. According to the City's “Helmet Policy For Ice Activities” which was approved August 16, 2002 and revised September 17, 2004, “All participants (preschool, children, youth, and adults) who participate in and play supervised shinny hockey, hockey, or power skate activities are required to wear Canadian Standards Association approved hockey helmets.” Also noted in the policy is that staffers “are required to enforce this Policy and they are to ask participants to leave the ice if they do not have the required CSA approved hockey helmet.”
