I hate to piss on the parade, but it reads to me like this judgement does not in fact allow women to say no to letting men into their homes. They're allowed to say no to a scrotum wax, if they don't know how to wax balls. They can't decline a man who asks for a leg wax if the man says he's transgender
I actually wonder whether they could refuse to wax the legs of a man (not trans) anyway or whether this would be sex discrimination. Under UK law you could refuse as long as it is objectively justified as there is an exception in the Equality Act in Sched 3, but I don't know whether there are similar provisions in Canadian law.
