Hockey Canada confirmed news of Benoit Groulx leaving his post as head coach of Canada's national junior team on Thursday.
Hockey Canada will now undertake the process of naming a replacement for Groulx. The process is expected to be a quick one, a source told The Canadian Press.
The coaching vacancy will have to be filled before the world junior championship in late December at Ottawa. But Hockey Canada says a timeline for the decision hasn't been set.
Canada has won four straight gold medals at the tournament.
Groulx, who had been the head coach of the QMJHL's Gatineau Olympiques, reportedly took a job in the American Hockey League.
He took over the reigns of the national junior team from Craig Hartsburg on June 20. Hartsburg led the Canadians to their last two gold medals.
