"However, not everybody thinks that the Snowflake is still good enough to denote a true winter tire. In recent years, Transport Canada has begun to push for a higher standard to be required for the Mountain Snowflake symbol. Nigel Mortimer, Head of Recalls in the Safety and Security group at Transport Canada says that “the snowflake is not doing the job anymore.” Mortimer argues that the reference tire, ASTM E-1136 is in fact an All-Season tire, and that winter tire technology has “evolved greatly” since 1999. "Some modern winter tires are now at 130 or 140 percent of the control tire's performance. We need to move to a higher standard.""
