Movie star Keanu Reeves signed a one-day contract with the Ontario Hockey League’s Windsor Spitfires on Thursday.

Reeves grew up in Toronto and was born in Beirut. According to NHL.com, the Matrix star was a goaltender and came close to trying out for the Spitfires when he was a teenager, but couldn’t because of injury.

It was to support the Canadian Mental Health Association’s Windsor-Essex branch, which will auction off signed items from the actor and all proceeds going to the organization.

Bidding is open on the Spitfires website. As of Friday afternoon, the top bid was $10,000 (now at $20,000).

The auction ends on Aug. 30.
