Alberta bans puberty blockers and cross-sex hormones for gender reassignment under 16. At 16 and 17, a child may still start them if a parent or guardian, a physician, and a psychologist all approve. A minor who had already started, and a minor with a disorder of sex development, are excepted. Sex-reassignment surgery has been banned for anyone under 18 since December 2024.

A male who identifies as a woman can be housed in a women's federal prison, even if his body is male and his identification still says male, unless a health or safety problem cannot be resolved. A federal count of 99 gender-diverse prisoners, from December 2017 to March 2020, found that 62 percent were males who identify as women. At the end of that count, 67 percent of that group were still in men's prisons. The federal women's prison in Alberta is Edmonton Institution for Women.
