Function name:CSA
The CSA executes tests, certification, quality examination, and registration on all products destined for Canada.

The CSA executes tests on all the products in accordance with the Canadian CSA standard and authorizes designation of the CSA mark on those products meeting the CSA standard.

There is no difference between the c-UL mark and CSA mark except for the individual institutions certifying them.
However, in both cases, products are subject to quality examinations in conformity with the CSA standard.

Since the U.S.A. borders on Canada, a mutual treaty has been enacted.
