You can't use a CNAME for the zone name itself.  A name cannot be both 
an alias and also have records of its own, and the zone name is required 
to have SOA and NS records of its own.  Ergo, it can't also be an alias.  
So you should do something like:

lifeboatscanada.com.  IN A     64.69.87.111
www                   IN CNAME www.qcislands.net.
ftp                   IN CNAME www.qcislands.net.

Also, don't forget the "." at the ends of "www.qcislands.net.".
