^Could you provide an exact quote, please? It's a 90-minute podcast and I'm just asking about one statement. As you've described it, it doesn't make sense. CBS doesn't have some office that defines what is canon. That's the purview of whoever's currently creating new Trek content, which is currently J.J. Abrams and his team. CBS's licensing department makes sure that tie-ins are consistent with canon, but the canon is defined as what's onscreen.
It starts about the 71:20 minute mark, and what he actually said was that they told him that "it was "canon" until somebody films something that says it not". Listening to what he says afterwards I'm kind of wondering if Goodman even is aware what canon actually is, since if you use his requirements (published/licensed by the producer of Star Trek (CBS) and not contradicting on-screen stuff) almost every novel is canon.
