Guys, I think that we've found the rub. UL is different than CSA in this regard (marking). UL can certify products for "dual" listing in US and Canada. CSA can also certify for dual listing in US and Canada.
However, there is a difference in the marking requirements. We have used CSA ourselves, so I went and looked at our latest product report. In the marking section it mentions that the CSA logo with the "C US" subscript is required. However, all of the other markings are manufacturer, model number, ... All information that we put on our existing serial/model tags. There is no requirement for file number, listing number ... (Specific information required by UL, see Kurt Andrews reply attached below) It appears to me that CSA (unlike UL) marking lends itself to using a generic label. So, I'm trying to find an approved source for a label with the CSA logo along with the "C US" subscript. Some of the replies that I have received have pointed me toward some vendors which I am going to check out. Stay compliant guys... and as always...if I've said anything wrong I only have myself to blame and I'm sure that one of my learned colleagues will set the record straight.
