S. William,
Thanks for the words on COs and TOs and SCCs. Apparantly UL is one or
more of these, as the c-UL mark is legally acceptable in Canada.
Now, what other COs has the SCC accredited to issue an approved Canadian
mark? Not CSA, but alternatives to CSA?

George, Canada is not as straight forward as that. There is not a mutual
agreement. In order for a lab to issue a Canadian Approval Mark, the lab
must be accredited as a CO(Certifying Organization) by the SCC(Standards
Council of Canada). The CO must use data that has come from a TO(Testing
Organization) that is also accredited by the SCC. Most labs that issue
their Canada Mark are both a CO and TO so it is very easy for them. The
critical item is that the product has to have been tested against the
relevant Canadian National Standard(very easy for ITE as 1950 is a joint
standard).
If you want to do everything by the book, your US Mark should be from an
NRTL certified by OSHA to the standards that apply to your product and the
Canadian Mark must be from a CO accredited by the SCC.

Subject: RE: NRTL acceptance
I tried to recall NRTLs that were approved for asessments of ITE to
UL1950. I did not overlook MET (listed in my note), but may have
missed NTS which may fit this description. I'm not sure the others
are sanctioned for listing of ITE under UL1950.
There are many NTRLs, including UL. There is no "NRTL" mark, as all
NRTLs are legally equal. The mark of some NRTLs has included the
letters "NRTL" as part of their mark, apparantly by choice. The
CSA/NRTL mark is an example. To my knowledge, the use of "NRTL" in
an agency's mark is not mandatory. CSA has recently changed their
mark to drop the "NRTL" and simply show the CSA mark with "US"
subscript for assessment to the U.S. stadnard.
However, Canada does not recognize the U.S. NRTLs to assess an ITE
product to the Canadian standard. There is a mutual agreement between
Canada and the U.S. that "allows" a UL assessment to the Canadian ITE
safety standard. This results in the UL mark with a subscript "C",
often called the "c-UL" mark. It is my understanding that when the
Canadian government bids out ITE for its own use, they tend to prefer
the CSA mark over the c-UL mark. This seems to violate the "spirit"
of the agreement, but who can force them to do otherwise?
