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 |

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. |
