Although born in Calgary, Alberta, Canadian Dorothy Kozak earned her reputation as an athlete in the province of Manitoba during the 1950s, where she was named top female athlete in 1953. The following year she was part of Canada's delegation to the 1954 British Empire and Commonwealth Games where she was eliminated in the heats of the 100 yards event, but won a bronze medal alongside Annabelle Murray, Geraldine Bemister, and Margery Squires in the 4×110 yards relay. In 1956 she represented her country at that year's Summer Olympic Games where, despite finishing last in the 4×100 metres relay, she helped set a new Canadian record for the event. She also competed in the long jump, placing 17th in a field of 19 competitors. Nevertheless, she set a Canadian record in this event later in the year. After retiring from athletics in the late 1950s she took up bowling as a hobby, finding considerable success and winning the A singles at the Manitoba Five Pin Bowling Association championship in the 1970s.
