10、ational Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certification activities. CSA standards re

Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supporting the Associat

Sustaining memberships represent a major source of income for CSAs standards development activities. Th

To ensure the integrityof its certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In addition to its he
