Note below that I did see the named.ca which is from their namecaching 
setup.  And this stub does not have as many AAAA records as the one I 
ftped, so it is already dated.

Which begs the next question I was going to ask.  How often should I 
download a fresh named.zone?  Do I set up a monthly cron job?  It is 
clear that there is movement on populating it with AAAA records.
