Canadian Standards Association (operating as “CSA Group”), under
whose auspices this National 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 Group standards reflect a national consensus of producers and
users — including manufacturers, consumers, retailers, unions and
professional organizations, and governmental agencies. The
standards are used widely by industry and commerce and often
adopted by municipal, provincial, and federal governments in their
regulations, particularly in the fields of health, safety, building and
construction, and the environment.
Individuals, companies, and associations across Canada indicate
their support for CSA Group’s standards development by
volunteering their time and skills to Committee work and supporting
CSA Group’s objectives through sustaining memberships. The more
than 7000 committee volunteers and the 2000 sustaining
memberships together form CSA Group’s total membership from
which its Directors are chosen. Sustaining memberships represent a
major source of income for CSA Group’s standards development
activities.
CSA Group offers certification and testing services in support of and
as an extension to its standards development activities. To ensure
the integrity of its certification process, CSA Group regularly and
continually audits and inspects products that bear the
CSA Group Mark.
In addition to its head office and laboratory complex in Toronto, CSA
Group has regional branch offices in major centres across Canada
and inspection and testing agencies in eight countries. Since 1919,
CSA Group has developed the necessary expertise to meet its
corporate mission: CSA Group is an independent service
organization whose mission is to provide an open and effective
forum for activities facilitating the exchange of goods and services
through the use of standards, certification and related services to
meet national and international needs.
