The short answerConditional

Attached decks require a permit. A detached uncovered deck can be exempt only when it stays within the City’s published area and height limits.

Vaughan requires a permit for decks attached to a building regardless of area or height. Its published exemption applies to an uncovered, detached deck no larger than 18.6 m² and no higher than 0.6 m above grade.
