Correct:

A Building Permit is required for the construction of a wood deck where the deck is more than 600 mm (approx 2 ft) above grade at any point. Depending on the height and size of the deck and the community in which you live, you may also require a Development Permit prior to obtaining your building permit.

For more information, please contact the Planning Services Support Centre at 403-268-5311.
