Trevor,
Good question. You must have been one of the earliest owners of the new licence. Like you, I couldn't find any reference to renewals on the CFC web site. I think your best bet is to go to the
CFC contact page and send them an e-mail message. My experience is that e-mail gets better results from the centre than the frustration of the telephone number, especially if you have some time to wait for them to reply. They usually do in a few days.
