Canadian Building permits require the CSA-A660-04....it's in the Canadian Building Code.     Not all steel building manufacturers are able to meet the High Standards of Quality set by

CANADIAN STANDARD CERTIFICATION.... A660. 

What is CSA-A660 Certification and what does it mean for you? The CSA-A660 Standard was developed to assist code enforcement officials in reviewing building permit submissions incorporating steel building systems and to help purchasers receive a Canadian Quality Certified Steel Building. As part of the CSA-A660 compliance, the manufacturer will provide a "Certificate of Design and Manufacturing Conformance" signed and sealed by a licensed Professional Engineer for each building project.
