Straight answers
The questions people ask most about starting and running a drywall business in Ontario. Answered straight, with links to the official sources.
Boarding pays fast and rewards raw speed and strength, but it's the harder lift-everything grind. Taping is easier on the back, more skill-based, and has the longer earning curve (top tapers make excellent money). If you want money this month, board; if you want a 20-year body and craft pricing, tape. The shops that own the full package do both.
When you're slow, hourly protects you from starving. Once you're fast, piece rate is where the real money is — you're paid for output, not time. Most residential drywall is piece rate; commercial and union lean hourly. Know your speed honestly before you choose.
Drywall dust is gypsum with silica in the joint compound — it's genuinely harmful, and "I'll be fine" is how people end up with lung problems. Never sand without at least an N95, and the pros use dustless sanding setups (a vacuum-connected sander like a Festool). It's the single best long-term investment you'll make in the trade.
Faster than most trades — there's no licence, the tools are cheap, and a fast solo taper or a two-person board-and-tape crew can sub for builders within a year or two of getting quick. The constraint isn't licensing; it's your speed and a builder relationship that keeps you fed.
It's the oldest rate trick in drywall. Pricing is really per square foot, but a "per sheet" quote hides the size: $X per sheet is very different if they're hanging 8-footers (32 sq ft) versus 12-footers (48 sq ft). Always convert to square feet and confirm board size before agreeing — and negotiate a heavy-board premium if you're also hanging.
It pays surprisingly well for how accessible it is — a fast taper can out-earn many licensed tradespeople, and small drywall shops are very profitable. The catch is the body and the speed dependence: your income is your output, so the smart play is to get fast, protect your lungs and shoulders, and move to running a crew before the grind catches up.
No provincial trade licence — drywall is non-compulsory. You need a municipal business licence, WSIB registration, and liability insurance. The 451A (installer) and 453A (finisher) Certificates of Qualification are voluntary but help win commercial contracts.
Drywall is one of the cheapest construction businesses to launch — tools, stilts, lifts, and a truck are the main costs. Add incorporation (~$400–$600), $2M CGL ($1,000–$2,500/year), and WSIB. Many start solo on residential boarding and taping and scale into commercial.
451A (Drywall, Acoustic & Lathing Applicator) installs the board, steel stud framing, and acoustic ceilings. 453A (Drywall Finisher & Plasterer) does the taping, mudding, and plaster finishing. Holding both lets a small shop self-perform a complete wall-and-ceiling package.
It is popular for first-time construction owners because the licensing barrier is low, equipment cost is modest, and demand is steady across new construction and renovation. Margins improve with crews, commercial work, and adding finishing (453A) so you self-perform the full scope.
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.
