Quebec Senator Jacques Demers is in hospital after suffering a stroke.
The condition of the 71 year old, best known for his time as an NHL coach, is unknown.
Demers was appointed to the Senate in 2009 by former prime minister Stephen Harper. He quit the Conservative caucus last December to sit as an independent.
Demers led the Montreal Canadians to a Stanley Cup victory in 1993.
He also coached the Quebec Nordiques, The Detroit Red Wings and the St. Louis Blues.
