Straight answers
The questions people ask most about starting and running a decorative concrete business in Ontario. Answered straight, with links to the official sources.
Yes — decorative is a craft layer on a flatwork foundation, not a shortcut around it. Stamped concrete is finished concrete plus artistry, under the same unforgiving time pressure as the concrete sets; if you can't place and finish a slab well, your decorative work will fail (and decorative failures are expensive and visible). The progression is flatwork competence → stamping and overlays → the polishing capital step. Skip the foundation and you'll learn it the hard way, on someone's patio.
They're very different businesses. Stamping (and staining/exposed-aggregate) needs modest tooling on top of normal finishing gear — mats, colour, release — and is residential, exterior, portfolio-sold. Polishing is the capital step: planetary grinders, dust extraction, and diamonds run tens of thousands, but the commercial polished-floor market (retail, warehouse) pays for it and increasingly specs certified installers. Many start with stamping/overlays on a flatwork base, then buy into polishing as commercial demand justifies it.
No licence — but decorative is a system, and manufacturer training is how you learn products that each behave differently: stamps and colour systems, overlay and coating systems, and (for polishing) densifiers and diamond progressions. ACI/CPC polishing credentials and manufacturer certifications are what get you specified on commercial work, where architects name certified installers. The training is the difference between consistent results and expensive callbacks on premium work.
Significantly — that's the whole point. Decorative is bought from photos, not on price, so good decorative crews escape the per-square-foot race-to-the-bottom that defines basic flatwork. Stamped patios and polished floors command craft margins well above plain slabs, you compete on portfolio and design rather than the lowest bid, and the work is somewhat easier on the body. The catch is the skill and (for polishing) capital required — but the margin upgrade is real and is why flatwork crews add it.
Deliberately, and from the start. Decorative is sold from photographs, so document every pour, build a few showcase projects (even at thin margin to get them), and let the gallery sell the next ones. Strong photos of stamped patios, polished floors, and stained finishes are your storefront — homeowners and commercial clients choose decorative installers by looking, not by lowest price. The portfolio is the marketing and the pricing power combined.
Stamping needs modest tooling (mats, colour, release, texturing skins) on top of your normal finishing gear — an accessible add-on for a flatwork crew. Polishing is the real capital step: a planetary grinder, dust extraction, and a set of diamonds run tens of thousands. Overlays and staining sit in between. The common path is to add stamping/overlays cheaply first, build the portfolio and demand, then make the polishing investment when commercial work justifies it.
Premium finishes: stamped and exposed-aggregate driveways and patios, polished concrete floors for retail/industrial, micro-toppings and overlays, and epoxy/urethane coating systems. The buyer chooses you from photos of your work — it is a portfolio business with craft margins well above flatwork rates.

A sole proprietorship is cheaper and simpler to start, but you are personally liable for the business's debts and claims. Incorporating creates a separate legal entity that limits personal liability, can reduce tax once you are profitable, and reads as more credible to larger clients. Most contractors incorporate once they have employees, real revenue, or work on others' property.
Yes — construction is a mandatory WSIB sector in Ontario. Even independent operators and partners with no employees generally must register, and clients and general contractors will require a valid WSIB clearance certificate before you can work on their site.
You must register for and charge HST once your revenue exceeds $30,000 over four consecutive quarters. Many contractors register before that threshold so they can claim input tax credits on tools, materials, and vehicles from day one.
Ontario's Construction Act sets the rules: a 10% holdback on most contracts, prompt-payment timelines (you must be paid within set periods after a proper invoice), and an adjudication process for disputes. Understanding holdback, lien rights, and prompt payment is essential to protecting your cash flow.
