Ottawa's landmark Chateau Laurier hotel going on the block The landmark Chateau Laurier hotel in downtown Ottawa is up for sale as part of its owner's plans to get out of that type of real estate. A spokesman for Ivanhoé Cambridge says the Montreal-based company, an arm of Quebec's Caisse de dépôt et placement du Québec pension management system, has already sold hotels this year in several Canadian cities, Paris and the United States. The strategy was announced last year but sales prices haven't been disclosed by Ivanhoe Cambridge.
