Holt Renfrew Ogilvy, formerly and still colloquially Ogilvy, is a luxury department store on Saint Catherine Street West in Montreal, Quebec, Canada. It was designed by David Ogilvy for his father James Angus Ogilvy, and opened in 1912. The store was acquired by Wittington Investments in 2011, which finished renovating, expanding, and consolidating the nearby Holt Renfrew department store on Sherbrooke Street West into the Ogilvy building in 2020. It spans 250,000 square feet of selling space, and is nicknamed the "grande dame of Saint Catherine Street" as the only one of four major west-end stores in the city to retain its original name.
