Amund,
I believe some additional clarification is warranted. UL and CSA are private agencies and do not determine what is acceptable to market goods (ITE) in their respective countries. This is determined by government bodies. The U.S. OSHA has approved multiple Nationally Recognized Testing Laboratories to (NRTLs) to perform testing to the UL standards for ITE. These include UL and CSA. See: http://www.osha-slc.gov/dts/otpca/nrtl/index.html The Standards Council of Canada has approved multiple "Certification Bodies" to perform testing to the CSA standards for ITE. These include UL and CSA. See http://www.scc.ca/certific/colist_e.html Neither UL nor CSA is obliged to recognize or "accept" testing performed by the other agency, although their respective governments do so. Canada requires either CSA, c-UL, or marks of the other listed certification bodies. U.S. requires UL, CSA/NRTL, or marks of the other listed NRTLs. So, you can use either agency to get a mark acceptable in both countries. However, here is the "down" side of each: CSA/NRTL--Not as well known in the U.S. by large corporate customers. Requires some "selling" to convince that it is equal to UL. c-UL--OK for both country consumer/business markets, but Canadian government tends to give precidence to CSA marked ITE when bidding for its own use.

CSA accepts approval by ULC. The C is indicative of Canadian UL.
