Charlotte was born a male but started living as a female at age 29. Following her sex reassignment surgery, Charlotte experienced physical and emotional abuse in a relationship, and she was referred to an organization that assists battered women. Several years later, she responded to an advertisement for volunteers at a rape crisis centre. Being a woman was stipulated as a job qualification.

Charlotte filed an application with the Ontario Human Rights Tribunal.
