TMX Group Remembers Stan Deudney, Founder and Former President of CDS

August 16, 2017 (TORONTO) - TMX Group today offers sincere condolences on the passing of Stan Deudney, the founder and first President of the Canadian Depository for Securities (CDS).

A champion of innovation and true pioneer in Canada's capital markets industry, Stan leaves behind a legacy of innovation. He was the architect and driving force behind the creation of CDS, Canada's equities and fixed income clearing house and served as CDS's first President and Chief Executive Officer from 1980 to 1983. He went on to establish the first discount brokerage in Canada and created the first global trade reporting system and settlement system in 1987. For the past 25 years, Mr. Deudney has served as president of Transatron Systems Inc., a provider of software and consultancy services to the financial community. In 2012, he was awarded the Queen Elizabeth II Diamond Jubilee Medal by the Investment Industry Association of Canada in recognition of his achievements in his career in the securities industry.

TMX Group and CDS extend sincere sympathy and condolences to Stan's wife Lucia and his sons Eric and Gordon and his grandchildren Claire, Michael, William and Jack.
