I solved the problem!  For some strange reason, time.nrc.ca does not
resolve to one IP address.  It resolves to two possible IP addresses!

"The service at time.nrc.ca is actually served by two servers at different
IP addresses.  The DNS server will resolve the lookup to EITHER server."

To get my Linux box to reliably link and synchronize with time.nrc.ca, I
had to add the TWO IP addresses to my restrict lines in my /etc/ntp.conf

restrict nomodify nopeer notrap noquery
restrict nomodify nopeer notrap noquery
restrict time.chu.nrc.ca nomodify nopeer notrap noquery

Note:  Only time.nrc.ca has this weird behaviour.  
       time.chu.nrc.ca resolves to ONLY one IP address.
