Orbiting Canadian astronaut Chris Hadfield may have lost a few fans after tweeting a picture of himself holding a Toronto Maple Leafs plaque.

Commenting on the end of the NHL lockout, Hadfield tweeted from the International Space Station on Sunday he was ready to cheer for the Leafs from orbit.

Professing his support for Toronto did not sit well with a number of hockey fans.

Former Montreal La Presse sports reporter Jean-Francois Begin jokingly warned Hadfield to be careful next time he flies over Montreal.

Hadfield is on a five-month visit to the space station and will become the first Canadian to take command of the giant orbiting laboratory in March.

Former Canadian astronaut Marc Garneau also got into the act. The Liberal MP tweeted Hadfield that he couldn't let his support for the Leafs pass without declaring: "Go Habs Go!"
