Yoon's works often employ photography, video, and elements of performance to question constructions of identity within specific historical and social conditions. In 1991, the artist produced a work entitled
Souvenirs of the Self, which explores the relationship between notions of
self and the
Other within dominant images of the Canadian landscape, most noticeably those shaped primarily by tourism. An installation created in 1998,
between departure and arrival, marks Yoon's shift away from only using photographic images as outward markers of race. Using video and audio in
departure, Yoon investigates "interior, consciousness forming structures such as language." The unconscious, memory, history, identity, place, and nationhood are important themes for the artist, whose project,
Unbidden (2004), uses multiple-channel videos and photographs to allude to the psychic and physical conditions of the subject, particularly through migration, diasporic dispersal, and displacement related to war and other geo-political conditions. Her work
Long View (2017) blends photography and video to tackle themes of identity, place, history, and surveillance. The work records a performance by Yoon's family where they dig into the sand on Long Beach in
Pacific Rim National Park Reserve.
Turning Time (2022) was composed of eighteen suspended digital screens projecting a diverse cast of dancers performing their own interpretation of the Korean Crane highlighting themes of interconnectedness, diasporic subjects, the future and resilience. In 2009, she was a finalist for the
Art Gallery of Ontario's Grange Prize and in 2013 was awarded a Smithsonian Artist Research Fellowship. In 2018, she was made a Fellow of the
Royal Society of Canada. In 2022, she won the
Scotiabank Photography Award. Her recent video work explores various cities, most notably in South Korea and Japan. Formally tipping the vertical city of skyscrapers and bipedal humans onto a horizontal plane, Yoon evokes subliminal and inchoate associations with both the past and the present. For viewers experiencing the work within the gallery there is an uncanny sense of a dream-like immersion in the phantasmagoria of late modernity. In 2025, she received a Governor General's Award in Visual and Media Arts for Artistic Achievement. Over the past fifteen years, Yoon has achieved international notoriety. == Select exhibitions ==
