Great research! If you look at the cover of the North American test catalog, you'll see a blue 50 note at the bottom - BCA-101. BCA is certainly still active! As you can see by this write-up in the catalog, the CCL is not CCL Industries, but CCL Secure, better known as Securancy, the maker of Guardian, the leader in polymer substrate production.
