You do not need a provincial licence to hang or tape drywall anywhere in English Canada. Drywalling is a voluntary trade: no certificate is required to board out a basement or finish a ceiling for hire. The one exception is Quebec, where construction-sector drywall work generally needs a CCQ competency card (the Commission de la construction du Quebec runs its own system). Everywhere else, what actually decides whether a general contractor will keep hiring you is your finish quality, your speed, and the fact that you carry liability insurance. This trade runs on per-square-foot pricing far more than hourly billing, so getting your square-foot numbers right is the whole business.
Licensing and certification: voluntary, with a Quebec exception
Across the rest of Canada there is no licence to hang or finish drywall. Red Seal credentials do exist, but they are split and uncommon in residential practice: the hanging side sits under Lather (Interior Systems Mechanic) and the finishing side under Drywall Finisher and Plasterer, two different designations. Red Seal is one of Canada's 54 designated trades. It is an endorsement on your certificate, not a licence, and it lets your qualification be recognised in other provinces. It signals competence to bigger commercial and multi-unit clients, but it is not a legal requirement to take residential work. Compulsory-versus-voluntary status varies by province, so check your province.
Quebec is the standing exception. For construction-sector drywall (new builds and major commercial projects) you generally need a CCQ competency card, and the contracting entity needs a Regie du batiment du Quebec (RBQ) licence. If you plan to work in Quebec, treat that as compulsory and confirm your sector with the CCQ before quoting.
Code that drives your material spec
Even without a licence, the building code decides what board goes where, and that flows straight into your quote:
- Fire separation. The National Fire Code and provincial building codes set drywall thickness and type in certain assemblies. Type X (fire-rated) board is required at party walls and fire corridors. Quoting standard board where a rated assembly is needed is a code failure that the inspector will catch.
- Moisture and wet areas. Moisture-resistant board (greenboard) and cement board are required in wet areas such as bathrooms and behind tile. This changes your material list and your price.
Pricing the right board into the job is part of doing it properly, not an upsell.
Kit and start-up costs (estimates, CAD)
Drywalling is one of the lower-barrier trades to enter. Indicative ranges, so confirm current prices:
- A drywall lift: roughly $800 to $1,500.
- Screw gun, sanders, knives and a hawk: roughly $600 to $1,500.
- A mixing drill and mud buckets: roughly $300 to $600.
- Stilts: roughly $200 to $400.
- CGL insurance: roughly $2,000 to $3,500 per year.
- A van or trailer: roughly $10,000 to $25,000 used.
A realistic first-year operating estimate lands around $20,000 to $40,000.
What you can charge (estimates, not fixed rates)
This trade is priced per square foot, and the per-square-foot number is the most-searched price in the trade. There is no single published national rate table, so treat these as indicative ranges that vary by region, scope and whether the job is cash or invoiced:
- Board (hang only), labour: roughly $0.28 to $0.60 per square foot, with the GTA and Atlantic Canada at the higher end and the Prairies lower.
- Taping, labour: roughly $0.40 to $0.50 per square foot.
- All-in Level 4 finish, painted (GTA): around $3.10 per square foot as a reference figure.
- Common jobs: a half basement (about 600 sq ft) roughly $2,500 to $4,500; a full basement (about 1,200 sq ft) roughly $4,500 to $9,000; a single-room patch roughly $200 to $600.
Confirm your own numbers against local subcontract rates, because the per-square-foot figure swings hard between provinces and between cash and invoiced work.
Common mistakes
- Quoting standard board where a rated assembly is required. Party walls and fire corridors need Type X, and the inspector will check.
- Skipping moisture-resistant board in wet areas. Greenboard and cement board are code in bathrooms, not optional.
- Pricing per square foot without accounting for height, access and detail. Cathedral ceilings and cut-up rooms are not the same rate as a flat basement.
- Forgetting GST/HST. Once your taxable revenue passes $30,000 over four consecutive quarters (or in a single quarter), you must register for GST/HST within 29 days of the effective date.
