Can a landlord specify a unit is only for male or female tenants?
No. According to the Ontario Human Rights Policy, a landlord cannot specify gender provided the accommodation is private and all the units in the building are not being rented to only one sex. It is against the law for landlords to discriminate against you because of race, sex, age, sexual orientation, marital status, colour, nationality, if you have a disability, are on social assistance or have children.
