In 1958 she married Hungarian-Canadian businessman Geza Por (d 1965) and moved to Toronto, where she founded the periodical Opera Canada which she edited 1960-90. In 1968, with Lloyd Bradshaw, she founded the Canadian Children's Opera Chorus and served as its first president. She served 1962-79 as host of CBC radio's weekly 'Opera Time' and 1979-84 of the revised and expanded version, 'Opera in Stereo.'
Mercer was the author of The Tenor of His Time (Toronto 1976), a biography of Edward Johnson, and The Quilicos - Louis, Gino and Lina (Oakville, Ont, 1990). She contributed articles to EMC, Musical America, and Opera News. After retirement in 1990, she continued to contribute columns and reviews to Opera Canada and to serve on its board and editorial committee. Mercer was awarded the Canadian Music Council medal in 1983, and a Toronto Arts lifetime achievement award in 1988. She received honours from the State of Ohio, and from Ohio University and Cincinnati College-Conservatory, where she provided voice scholarships; she also provided a scholarship at the Banff Centre, and endowed an award for University of Toronto's Opera Division. She was invested as a member of the Order of Canada in 1995. In 1997 she donated her papers to the National Library of Canada.
Mercer has been recognized as a champion of opera in Canada and as pivotal in raising the profile of Canadian artists at home and abroad. Writing in Opera Canada about her contribution to that magazine and the CCOC, Louis Quilico said, "Her soul and spirit went into these organizations and made operatic life in Canada vibrant and meaningful."

Besides hockey and the maple leaf, there is little as symbolically Canadian as the CBC – the Canadian Broadcasting Corporation. It grew out of a developing nation's need to express its identity and find its voice.
