Isaacs moved to Canada to serve 1963-74 as director of the School of Music, University of Manitoba, and after his retirement from that position he was visiting professor 1974-5 at the University of Calgary and gave courses at Carleton University and at the Banff SFA. In the 1970s he was heard frequently on CBC radio programs, as commentator on 'Canadian Concert Hall,' 'New Records,' and 'In Concert,' as host for the CBC Winnipeg Festival (1975-7), and as writer-commentator for the special series 'Chamber Music' (1976) and 'The Human Bach' (1977). In 1982 Isaacs became professor emeritus at the University of Manitoba; he continued to teach privately.
Isaacs' published works include Four French Canadian Folk Songs (Schott 1959) for soprano and harp or piano, piano duets and trios for festival use issued 1954-5 by Curwen, and an arrangement of Bach's The Art of Fugue for chamber orchestra (Augener 1952). The latter was recorded by George Malcolm and the Philomusica of London (2-Argo ZRG 5421-5422/SDD-356-7), by the CBC String and Woodwind Ensemble under Alexander Brott (RCI 126), and by a string and woodwind group under Isaacs (RCI 157). Isaacs also contributed articles to EMC, and completed his memoirs in 1996. He continued giving performances and lectures until November 1997.
