A B.C. Supreme Court judge blocked a teenager from undergoing a gender-affirming double mastectomy in Vancouver earlier this month, granting the 17-year-old’s disapproving mother an order to stop the operation the day before it was scheduled to go ahead. The teenager, who was assigned female at birth and began hormone treatment in July as part of their transition, was set to have the mastectomy last Friday. The mother sued the teenager’s doctor and cosmetic surgeon on Nov. 3, demanding they stop treating her child without her permission until the courts can rule on consent. Justice Shelley C. Fitzpatrick granted the mother’s request and issued a temporary injunction blocking the surgery on Thursday, about 24 hours before the scheduled operation.
