More than 11,000 Calgary hockey parents have passed a new, mandatory online course aimed at curbing parental rink rage.

The deadline for parents to finish the Respect in Sport Course offered by Hockey Calgary was last Friday.

The course is mandatory for parents whose children play in the age categories between Timbits and Junior B.

If the course isn't completed by a parent, their children will not be allowed on the ice for games, practices or any other team activity.

Hockey Calgary president Perry Cavanagh said about 100 parents have yet to sign up. He expects many of those parents have no intention of completing the course.

"The completion requirement is 100 percent within their control. If they're not certified at this point in time, it is because they have chosen not to," said Cavanagh.

Cavanagh believes Calgary will be the first minor hockey system in North American to make a respect course mandatory for parents.

Hockey Calgary oversees 15,000 young hockey players in Calgary. Last year, the organization offered the course on a voluntary basis.
