The Challenge de Curling de Gatineau (formerly the Challenge Chateau Cartier de Gatineau and the Challenge Casino Lac Leamy) is an annual bonspiel, or curling tournament, on the World Curling Tour.
It is held annually in late October in the City of Gatineau, Quebec.
Beginning in 2011, the event shifted venues to the Centre Sportif Robert Rochon in Masson, Quebec in the Masson-Angers sector of the city and the Buckingham Curling Club in the Buckingham sector.
Former Brier champion Jean-Michel Ménard defeated 2007 Canada Games curling silver medalist Neil Sinclair to win $8,000 for his team.
The winner, Serge Reid, upset defending championship Jean-Michel Ménard and earned the right to play at the 2010 Canada Cup of Curling.
