Le Diamant sits in Mirabel, northwest of Montreal in Quebec's Laurentian foothills. Designed by Canadian architect Darrell Huxham and opened in the mid-1990s, the course occupies rolling terrain that transitions between open farmland and wooded corridors, a landscape characteristic of this part of the province. Huxham, who has designed several courses across Quebec and Ontario, routed the layout to take advantage of the property's natural elevation changes and mature tree stands. The course plays through a mix of environments. Some holes move across open ground where wind and sightlines become factors, while others turn through denser forest where accuracy off the tee matters more than distance. Water features appear on several holes, and the green complexes incorporate modest undulation and bunkering that reward precise approach play. The routing returns to the clubhouse at the midpoint, a common feature in Huxham's designs that offers flexibility for different formats of play. Le Diamant serves a regional membership and attracts golfers from the greater Montreal area seeking a full-length layout outside the city. The facility includes practice areas and a clubhouse with dining services typical of semi-private clubs in the region. The course remains walkable despite its terrain, and conditioning standards reflect the relatively short Quebec golf season, with peak playing conditions arriving in summer and early fall.
