Under the guidance of Nancy Lima Dent, Laya Liberman and Marcel Chojnacki, Heroes of Our Time was created collectively by members of the New Dance Theatre. Collective creation was a seldom-used choreographic tool at that time. 1952 was the last time the New Dance Theatre participated in the Canadian Ballet Festival. It is rumoured that festival organizers felt the group's ideals fell too far left of centre although there is no written documentation to support this theory. The expulsion of the UJPO, and other left-wing groups, from the Canadian Jewish Congress in 1951 may have made the Canadian Ballet Festival Association nervous about associating with a pro-socialist group during the height of McCarthyism. While the House Committee on Un-American Activities is well noted in history texts, communists were also persecuted in Canada in the 1950s.
