Police have just confirmed the search has now resumed for a Canadian man missing in the Snowy Mountains for over a week.

The search was called off yesterday afternoon, as authorities waited for a break in weather conditions.

They're holding grave concerns for the 25-year-old Bond University student, reportedly missing since last Monday.

Temperatures over the past week have stayed close to zero, with the first snowfall.

The alarm was raised when his car was found at Charlotte Pass Village, a rental that was due back last Wednesday.

It's believed the man set out to hike from that location to Mount Kosciuszko, but he hasn't been seen or heard from since.

The National Parks have today added skidoo operators and skiiers to the search party.
