About us

Cosner Art Gallery historic 

Robert Tremblay, owner of the Cosner Gallery began his career 30 years ago. At the time, the company was specialized in the sale and purchase of Canadian and Quebec antiques. Over time, Mr. Tremblay was able to improve his knowledge in the Canadian visual arts, hence becoming an expert in the field.  For many years, he was chairman and auctioneer of the l’Hôtel des Ventes Universelles, the ancestory company of Cosner Auction. The auctions were first held at the Capitole de Québec and the Ritz-Carlton Montreal, for many years to follow they took place in the ballrooms of the Windsor Hotel in Montreal.

Since 2011 Cosner Auction became the Cosner Art Gallery with the main focus of selling and buying Canadian art. Located in prime locations of downtown Montreal, the gallerie present works by Quebec and Canadian artists from private collections and estates. Giving our clients the chance to see and purchase unique paintings that have long been hidden from the public.

June 2016, Galerie Cosner inaugurated a second gallery in the prestigious Ritz-Carlton Hotel Montreal. Respecting the highest standards associated with the hotel, this art gallery offers a remarkable selection of artworks by Canadian masters.

Cosner art galleries take pride in advising and guiding their clients in the sale and acquisitions of Quebec and Canadian art.
