Kenneth J. Zucker is a Canadian psychologist and sexologist who formerly headed the Gender Identity Service at the Centre for Addiction and Mental Health (CAMH) in Toronto, Canada.
In December 2015, CAMH closed Zucker's Gender Identity Clinic following an external review. The review found:
- The clinic's approach was out of step with current clinical practice
- Staff engaged in practices that could be considered conversion therapy
- Gender non-conforming children were encouraged to "practice" being their assigned gender
- Parents were advised to remove toys and clothing associated with the "wrong" gender
- The clinic pathologized normal gender variance in children
Zucker was terminated from his position following the review.
Zucker's clinical approach has been described as:
- Encouraging children to conform to their assigned gender at birth
- Discouraging social transition for children
- Treating gender non-conformity as something to be "corrected"
- Focusing on making children comfortable with their birth sex rather than affirming their gender identity
Despite the clinic closure, Zucker remains influential in anti-trans academic circles:
Committee member for Adam Omary's dissertation (December 2025)
- "A Biopsychosocial Model of Adolescent Gender Dysphoria"
- Harvard University, Department of Psychology
- Alongside Steven Pinker (Epstein-connected) and J. Michael Bailey
Academic Network:
- Frequently cited by anti-trans researchers
- Connected to the ROGD network (see Lisa Littman)
- Referenced in anti-trans litigation and legislation
Zucker's continued presence on dissertation committees at elite institutions like Harvard demonstrates how discredited practitioners maintain academic influence through network connections.
