A habitable room is defined in the Toronto Municipal Code Chapter 629, Property Standards (Article 629-25) as: A room in a dwelling designed and lawfully used or capable of being lawfully used for living, sleeping, cooking or eating.
The maximum number of persons living in a habitable room cannot exceed one person for each nine square metres of habitable room floor area.
Please note, the calculation is different if the room is used for sleeping. Any floor area under a ceiling that is less than 1.4 metres in height shall not be counted in computing the required minimum floor area of a room used for sleeping.
