Brampton also sets limits for combined area, height, and location; check the linked city page for the details and exceptions.
Deck
A deck attached to the house or more than 600 mm (about 24 in) above grade needs a permit. Low, freestanding decks generally do not.
Fence

The provincial baseline
Under the Ontario Building Code, a detached one-storey storage shed of 15 square metres (about 160 square feet) or less, with no plumbing, does not need a building permit. Anything larger, with plumbing, or attached to another building does. Zoning rules (setbacks, height, lot coverage) always apply even when no building permit is needed.
