Already the highest-grossing single collection of Canadian art sold at auction at nearly $30 million, one of Canada’s most-significant private Canadian art collections has its final session

Toronto, ON (October 23, 2023): Rare and important artworks from several prominent private and public collections will go under the auction hammer in Cowley Abbott’s fall auction of Canadian and international masters on Wednesday, December 6. This two-session live auction is valued at over $10 million.

Highlights of the first session include two canvases by abstract painter Guido Molinari,deaccessioned by the Art Gallery of Ontario (AGO) and five notable works by Canadian artists William James Bennett, Jack Bush, Marc-Aurèle Fortin, Jean Paul Lemieux and David Milne, from the collection of the late Joe and Anita Robertson.

Born in Montreal, Molinari (1933-2004) was named an Officer of the Order of Canada in 1971 and achieved international renown, having exhibited in New York and at the 1968 Venice Biennale, and was featured in retrospectives at the National Gallery of Canada, Art Gallery of Ontario and Musée d’art contemporain de Montréal. His art is actively pursued by collectors around the world. Molinari is represented by major works in the AGO’s collection, as well as across Canada. Following museum guidelines, the proceeds of deaccessioning go towards future acquisitions.

The two works up for auction are Seriel, 1966 (auction estimate: $125,000 – $150,000) and Quantifcateur, 1981 (auction estimate: $70,000 – $90,000).

“It is our privilege to represent the Art Gallery of Ontario and the Collection of the late Joe and Anita Robertson in the offering of these Canadian artworks. Our firm has a history of success in the sale of Molinari’s work and they are already inviting strong interest from collectors. It is a pleasure to collaborate with our colleagues and neighbours at the AGO and we are thrilled to donate a portion of our commission to support future acquisitions by the institution.” – Rob Cowley, President, Cowley Abbott

From the collection of the late Joe and Anita Robertson, prominent Niagara region businesspeople and philanthropists, comes four spectacular paintings and a collection of four prints. The Robertson’s made major financial contributions to the performing arts and health organizations, and were active supporters of the United Way, among many other charitable causes.

From an early New York canvas by David Milne (Billowing Trees, estimate $100,000 – $150,000); to a rare, large canvas by Jack Bush of Port Loring (Sunset at Port Loring, estimate $25,000 – $35,000); to William James Bennett’s captivating scenes of Niagara Falls (four aquatints, estimate $15,000 – $20,000) and a pair of celebrated subjects by Quebec masters, Jean Paul Lemieux (Femme en noir, estimate: $150,000 – $200,000) and Marc-Aurèle Fortin (Vieille maison, estimate $40,000 – $60,000), each work of art was carefully chosen by the Robertson, who have been advised by Brett Sherlock through the auction process. Cowley Abbott will donate a portion of their selling commission to the United Way Niagara Falls in memory of Joe, Anita and their daughter Laura, who passed away in 2018. An online auction of artwork from the Robertson Family Collection will also be held by Cowley Abbott this fall.
