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.
