The disclaimer might apply in some jurisdictions
but in Canada the copyright in a work exists from the instant it is created, and
there is no need to register anything. Proof is another matter, but a quick and
cheap way of providing legal proof is to give the national archives two copies
of whatever you publish.
This is likely the same pirated thing that's been
going around for ages, with material lifted from PODSnet of fond memory. I'll
check to see if any of my youthful maunderings made it into the compendium.
