June Clark moved from New York City to Toronto in 1968, a time when America was undergoing great turbulence. Martin Luther King Jr. and Robert F. Kennedy were assassinated in April and June of that year. The Vietnam war was raging, and the civil rights movement was marching. In the 1970s, Clark presented her photo-based texts, collages, and installations in both cities, each of which influenced her work; and yet she gravitates to the unknown. “It was both the discovery of the unfamiliar and memory of the known,” she once said, “that captured my imagination.” This large exhibition in her adopted city features four significant bodies of Clark’s work, from the 1990s to today. —Elena Clavarino
