Looking at prefix.cc I note that you have xhv: as the namespace prefix 
for many of the IANA properties that drive Web Linking. Thus, you have 
xhv:canonical as the URI for what you see in <link rel="canonical" .../> .

Thus:

:canonicalURI owl:equivalentProperty xhv:canonical;
    rdfs:subPropertyOf owl:sameAs.

## for good measure
xhv:canonical rdfs:subPropertyOf owl:sameAs .

As per my earlier comment, I encourage you to model and crack on, then 
map as and when you discover other ontologies. At the end of the day, 
you are simply trying to align entity relationship semantics between 
your world view and that of others  :-)
