1. Check the Builder’s Credentials, Licenses & Insurance
Before talking design, materials, or budget, the first and most important step is confirming that your builder is properly licensed, insured, and professionally qualified. Homeowners don’t need deep industry knowledge to make a safe choice—just knowing what to look for helps you filter reputable builders from risky ones.
Essential Licenses & Proof You Should Ask For
A reliable builder is always prepared to share documentation. At a minimum, you should expect:
Business registration
General contractor license (varies by municipality)
WSIB coverage
Liability insurance (ideally $2M or more)
Builder’s risk insurance (recommended for new builds and additions)
TARION/HCRA registration (for new home construction, if applicable)
These protect you financially, ensure compliance with Ontario regulations, and reduce surprises if an incident occurs on-site.
Memberships & Professional Associations
Memberships aren’t mandatory, so homeowners shouldn’t be alarmed if a builder isn’t part of them.
However, being associated with well-known industry organizations can signal professionalism, accountability, and ongoing education.
Common associations in Ontario include:
BILD (Building Industry and Land Development Association)
OHBA (Ontario Home Builders’ Association)
CHBA (Canadian Home Builders’ Association)
RenoMark
CSC (Construction Specifications Canada)
Membership often means the builder follows specific standards or codes of conduct, attends industry events, stays informed about regulatory changes, and invests in staying current with best practices. Homeowners don’t need to know every association—just recognize that these affiliations generally reflect a builder’s commitment to quality and professionalism.
