Born in
Philadelphia,
Pennsylvania, Blackbridge moved to
British Columbia with her family as a teenager, and has worked and resided in Canada ever since. Along with artists
Susan Stewart and
Lizard Jones, she has been a member of the
Vancouver-based
Kiss and Tell collective.
Kiss & Tell: Lesbian Art & Activism, the 2025 book published by the Art Canada Institute, explores Persimmon's biography, career, and activism through her work in the collective. A portrait of Blackbridge, by her Kiss and Tell colleague Susan Stewart, is held by
The ArQuives: Canada's LGBTQ2+ Archives' National Portrait Collection, in honour of her role as a significant builder of LGBT culture and history in Canada.
Major exhibitions Doing Time was Blackbridge's 1989 exhibition at the
Surrey Art Gallery, created in collaboration with ex-prison inmates Geri Ferguson, Michelle Kanashiro-Christensen, Lyn MacDonald and Bea Walkus. Incorporating twenty-five life-sized cast-paper figures of the four women, the installation also included texts written by the participants. This marked the first exhibition where Blackbridge worked with large-scale multi-media assemblage.
Still Sane was her 1984 exhibit in collaboration with
Sheila Gilhooly at Women in Focus gallery. This exhibition focused on Gilhooly's experiences of being institutionalized for being a lesbian. To create this exhibition, Gilhooly and Blackbridge spent 36 months creating a sculptural and written record of Gilhooly's time incarcerated in the hospital. Both
Still Sane and
Doing Time were cited in the awarding of the 1991 VIVA award to Blackbridge. In 2016, her exhibition
Constructed Identities was the first to open
Tangled Art Gallery, a fully accessible gallery dedicated to art focused on
disability issues. The Constructed Identities exhibition aims to disrupt the current aesthetic of disability in society. It addresses intersections of race, sexuality, ability and gender constructs. The content of the exhibition and gallery it was shown in, Tangled art Gallery in Toronto, highlighted the importance of the shift in perspective about people with disabilities. The collection of works is made up of mixed, found materials to create bodies that explore the variety of disability and what people look like when their bodies do not conform. == Disability in the arts ==
