Benoit Groulx has accepted a job as coach of the Rochester Americans of the American Hockey League, which means a job vacancy has opened up for the head coaching position of Canada's world junior hockey championship squad.

Groulx, 40, had been named as coach of the Canadian team in June. He spent the last seven years as a junior coach in the Quebec Major Junior Hockey League, guiding the Hull-Gatineau Olympiques.

Groulx led the Olympiques to three Memorial Cup berths in the last six seasons.

Canada will be vying for its fifth consecutive under-20 championship, matching a mark set in the 1990s.

The tournament will be held in Ottawa, with Canada beginning its schedule of games Dec. 26 against the Czech Republic at Scotiabank Place.

Hockey Canada said in a statement that it hasn't set a timeline for selecting a replacement for Groulx.

Craig Hartsburg coached Canada to its last two wins. Hartsburg is the new coach for the Ottawa Senators.

Rochester recently severed ties with the Buffalo Sabres, the longest NHL-AHL partnership. The Americans are now the sole affiliate of the Florida Panthers.
