Certifications Your Welder Should Have

Structural and architectural welding on a permitted custom home in Ontario carries specific certification requirements. Verify the following before issuing your subcontract:

Certification

Why It Matters

When Required

CWB (Canadian Welding Bureau)

Confirms welding competency to CSA standards

All structural welding

WSIB Registration

Protects you from liability if worker is injured on your site

Always - no exceptions

General Liability Insurance

Covers property damage during welding

Always - confirm $2M minimum

Working at Heights

Required by Ontario law for elevated work

Any work above 3m

Boom / Scissor Lift License

Required to operate elevated work platforms

When lifts are used on-site



Important

Always request certificates of insurance and WSIB clearance in writing before work begins. Your project's general liability coverage may not protect you if an uninsured subcontractor causes damage or injury.
