Before you hire any builder

  • Look the builder up on the HCRA Ontario Builder Directory. Anyone who builds a new home for you in Ontario must hold an HCRA licence, and the directory shows their licence status and history.
  • Ask for at least three recent completed homes you can drive past, and talk to those owners.
  • Ask for proof of liability insurance and a WSIB clearance certificate.
  • Get the scope, allowances, payment schedule and holdback in a written contract before any deposit.
  • Know your all-in budget first. The custom home cost calculator gives you a starting number.
