École secondaire Mont-Saint-Sacrement, Private high school in Saint-Gabriel-de-Valcartier, Canada.

École secondaire Mont-Saint-Sacrement is a private coeducational secondary school on a wooded, hilly site in the Laurentides massif, near the Jacques-Cartier River and a small lake. Its buildings were originally the Valcartier Ski Lodge, a resort hotel and alpine ski centre, which explains their unusual lodge architecture.

The buildings began as the Valcartier Ski Lodge, an alpine resort with a hotel and ski centre. The Religieux du Très-Saint-Sacrement acquired the site in September 1954, and the school opened in 1955 under the Fathers of the Blessed Sacrament. They directed it until 1982, when a private corporation took over; boarding ended in 1965.

The school incorporates outdoor activities into its daily teaching, with students engaging in climbing and paddling on the grounds. These pursuits are woven into the regular school experience.

The campus sits on a wooded, hilly site in the Laurentides massif near the Jacques-Cartier River and a small private lake, with cross-country ski and running trails, climbing walls, a skating rink and a sand volleyball court on the grounds. It is a private mixed secondary school in Saint-Gabriel-de-Valcartier, north of Quebec City, offering the regular enriched program and the International Baccalaureate programme.

The school's sports teams are all called the Lynx, and the school is known for basketball, volleyball, rugby, badminton and ultimate Frisbee. In 2005 it ranked 75th provincially in L'Actualité magazine's high school rankings, with 763 students that year.
