"We'd love to have the deck done for Canada Day." I hear it every spring, usually in May, sometimes — bravely — in mid-June. Sometimes it can still be done. But the honest backwards-count from July 1 does not start in May. Let me lay it out the way I lay it out at a kitchen table, so you can see where the weeks actually go on a deck build.
The build itself: 1 to 2 weeks
A typical backyard deck — footings, framing, decking, stairs, railing — is one to two weeks of work depending on size and complexity. This is the part people picture when they picture the timeline, and it is the shortest part of it.
Footings: the part winter decides
In Simcoe County the frost goes deep, and deck footings have to go below it — four feet down is the working number here — or the deck will heave every winter and settle every spring, racking the framing and popping the fasteners as it goes. We have a whole article on why decks heave if you want the deep version.
What matters for your calendar: footing holes get dug and inspected before concrete is poured, and that inspection is a scheduling step with the municipality, not a phone call the same morning. In a busy spring, booking the inspection adds days. Wet spring ground adds more — you cannot dig clean holes in soup.
The permit: 2 to 6 weeks
Most decks need a building permit — in general terms, a deck more than about 24 inches above grade, or attached to the house, or serving a door, is permit territory in Ontario municipalities, and that includes most of the decks people actually want. The application needs a site plan showing the deck against your lot lines and setbacks, plus construction drawings: footing size and depth, post and beam sizes, joist spans, guard details.
A clean application in a quiet month might turn around in a couple of weeks. The same application in late spring joins the queue of every other deck, addition, and garage in the municipality. Two to six weeks is the honest range, and none of it is compressible by asking nicely.
Materials: 1 to 4 weeks
Pressure-treated lumber is usually quick. Composite decking in the colour you actually want, aluminum railing systems, and specialty hardware can run two to four weeks in season — and starting the build without the railing on site is how a deck ends up 95 percent done on July 1, with the guard — the part the code and your kids both care about — arriving July 9.
The backwards-count, honestly
- July 1: deck done, guard on, first barbecue.
- Mid-June: build starts (materials on site, permit in hand).
- May: permit in review; materials ordered once the design is final.
- Late April: drawings done, application submitted, lumber list settled.
- This week: the first conversation — design, measurements, the written estimate.
Count it yourself: it is four to six weeks of paper and ordering in front of one to two weeks of building, and the paper does not speed up in June. It slows down, because everyone who did not have this conversation in April is in the same queue.
If you are already past April
Not every deck needs the full runway. A small, low, freestanding deck may sit outside permit territory. A repair or a re-deck of a sound existing frame skips the footing and permit steps entirely. The point of the spring conversation is finding out which deck yours is while there is still time to choose — not a lecture about the calendar.
So if a deck by Canada Day is the plan, the meeting is the build's real first step, and it is free.
