What makes a Canadian deck different

Most of a good deck is the part you never see.

Freeze–thaw cycles lift shallow footings, snow loads roofs and pergolas, and municipal permits kick in sooner than most homeowners expect. We design for all three from the first sketch.

1.2m

Minimum footing depth

The Ontario Building Code puts deck footings at least 1.2 m below grade, beneath the frost line.

600mm

Where permits and guards begin

About 24 in above grade is the line in Ontario municipalities and cities like Calgary.

Footing, framing, final

The typical sequence when a permit is issued. We schedule each one into the build.

General guidance from published municipal deck guides. Your municipality's rules govern.

Programme

Start with how you'll live out there.

The use decides the size, the height, the structure and even the permit. So we ask about dinners, hot tubs and grills before we talk about boards.

Raised deck with a dining set and glass guard

Dine

Room for the table, and for chairs to pull out without hitting the guard.

We lay out furniture before we frame.
Cedar pergola over a lounge area at dusk

Lounge

Deep seating, a fire table, and shade for long evenings.

Pergola posts land on their own footings.
Hot tub deck enclosed by a horizontal-slat privacy wall

Soak

A hot tub behind a privacy wall, ready year-round.

A filled tub is a concentrated load; framing is designed for it.
Covered outdoor kitchen with built-in grills beside a dining table

Cook

A covered outdoor kitchen with grills and a dining zone.

Gas and electrical work is done by licensed trades.

Section drawing: every deck we build starts here.
Sheet S-101 preview

Every deck starts as a section drawing.

Before we talk colours, we draw the deck in section: footings, posts, beam, joists, decking and guard. That drawing is what your permit office reviews and what your crew builds from.

  • Frost footings or helical piles, chosen for your soil and access
  • Framing sized for snow, hot tubs and roofs
  • Guards and stairs laid out to code before we price

Size it, price it, check the permit in two minutes.

Drag the dimensions, pick a height and a board, and watch the plan redraw. You get a planning range from published 2026 Canadian price guides, the guard height, a footing count and a permit flag.

Calendar

Design in winter. Build when the ground thaws.

Footings need thawed ground, and permits take time. The best-run projects are drawn and approved before spring.
