How to Hire a Drywall Contractor in Ontario
Drywall installers and tapers in Ontario are governed under the Skilled Trades Ontario Act — taping/finishing is a voluntary trade (not compulsory), but professional finishers often hold Red Seal certification. Quality finishing is critical: poor taping shows through paint. Always ask to see previous work before hiring.
Ontario Drywall Licensing Requirements
No mandatory Ontario licence
Drywall is not a regulated trade in Ontario, but professional plasterers and drywall tapers should carry liability insurance and WSIB. Large commercial drywall projects may require membership in the Drywall Acoustic Lathing and Insulation (DALI) Local 675.
