About BuildPlanner

Our Mission

BuildPlanner.ca exists to give Canadian homeowners, contractors, developers, and DIY builders practical tools to plan and budget construction projects with confidence. Pricing a garage, ordering gravel, or sizing up a raw lot shouldn't require guesswork — or a dozen phone calls just to get a ballpark.

How Our Calculators Work

Every cost calculator uses researched Canadian-average prices as defaults — and every price is editable. Material and labour costs vary widely across the country, so we'd rather hand you the math with honest defaults than pretend one number fits Victoria and St. John's alike. Adjust the unit prices to match local quotes and the estimate becomes yours.

Our estimates are planning tools, not quotes. We show ranges, not false precision, and we tell you when a result needs professional confirmation.

Who's Behind This

BuildPlanner.ca is built by a land development engineering professional with hands-on experience in construction costing, municipal servicing, drainage, and site development across Canadian projects — the person who has reviewed the soil reports, priced the gravel, sized the culverts, and watched budgets meet reality on real sites.

That background shapes how every tool here works: quantities calculated the way estimators actually calculate them, honest ranges instead of false precision, and a deal-breakers-first approach to decisions — because the most expensive problems are the ones found after closing, not before. We're not affiliated with any contractor, supplier, or manufacturer, and our calculators don't favour anyone's products.

Our Editorial Standards

Every guide on this site is written to resolve a decision, not to fill a page. That means each one states plainly what we'd do and why, names the conditions that should make you walk away, and lays out the safest sequence to follow. If a guide can't help you decide something, it doesn't belong here.

We fact-check with sources. Prices, code thresholds, dimensions, and lifespans are checked against current Canadian data rather than written from memory, and anything we can't confirm is flagged as needing verification rather than presented as fact. Where published sources disagree — and on construction costs they frequently do, sometimes by a factor of two — we say so and explain what's driving the spread instead of picking a number and pretending it's settled.

Prices have one source of truth. A figure quoted in a guide and the default in the matching calculator are the same figure, maintained together, so the two can't drift apart and contradict each other.

We update rather than accumulate. Construction prices and building regulations change. We would rather maintain a focused set of tools and guides properly than publish a large library that slowly goes stale.

What We Don't Do

Being clear about the limits is part of being useful.

We don't give professional advice. Nothing here is engineering, legal, or planning advice, and no calculator output is a quote. Building regulations are set provincially and administered municipally, which means the authoritative answer for your specific property always comes from your local building department — not from a website. Every tool here says so, and we'd rather send you to make a free phone call than let you rely on a national average.

We don't sell your attention to the highest bidder. The calculators don't favour any manufacturer's product, no supplier pays for placement, and the comparisons say when the cheaper option is genuinely the better one.

We don't pretend to precision we don't have. Site conditions — soil, rock, water table, access, distance from a supplier — move real costs more than any published average can capture. That's why results are shown as ranges, and why the tools tell you which unknowns are worth paying to resolve early.

Bilingual by Design

Every tool and guide on BuildPlanner.ca exists in both English and French. Not machine-translated as an afterthought — written in both languages, with Canadian French terminology and fr-CA number and currency formatting. Construction is a national activity in a bilingual country, and someone planning a garage in Gatineau deserves the same quality of information as someone planning one in Guelph.

Corrections in particular are welcome. If you're a contractor, supplier, or building official who sees a number that's wrong for your area, telling us makes the tool better for everyone who uses it next.
