The Ontario Building Code | Two Separate Exits
9.9.9.2. Two Separate Exits
(1) Except as provided in Sentence 9.9.7.3.(1), where an egress door from a dwelling unit opens onto a public corridor or exterior passageway it shall be possible from the location where the egress door opens onto the corridor or exterior passageway to go in opposite directions to two separate exits unless the dwelling unit has a second and separate means of egress.
In Plain Language
Where two exits are required, they must be arranged and separated as set out in this article, ensuring a single incident can't realistically block both of them.
