I live in Kitchener, so have been watching Richard's improvements as
I make my own edits. Very nice.

One minor nit (in general, not about Richard's work): Having the
canvec data is very nice but it can be rather tedious tracking down
all the unconnected roads (there are a LOT of them). I hope future
improvements in the import process will reduce the number of these.

I am the one who reported the railway which no longer exists. What is
the best way to deal with this? It shouldn't be removed outright as that
will just cause pain at the time of the next import. I am hoping that
removing the 'railway: rail' tag will do the trick - the (old) rail will
will still be in the database but it wouldn't be rendered. In particular
it is hoped that the existance of a matching canvec:UUID will cause the
next import to not import the object. Is this correct?
