I wouldn't know how to isolate the news paths, but here is a first attempt
at a map of Toronto's uucp connections in general.

I should explain a few things.  The first difficulty encountered by your
would-be map-maker-of-toronto is that everybody and their Apple ][ has
connections to one (and usually more) of {utai,utcs,utcsri,utzoo}.  I saw
so many machines with connections to both utcs and utzoo that I am beginning
to suspect they are really the same machine :-).  Anyway, rather than try to
put these machines in the middle of a spider-web of lines, I decided to
indicate with the machine name which of these four U of T sites they
connect to.  So "ms(a)" means that machine "ms" has a connection to utai,
in addition to any other lines you see on the map.  And "lsuc(crz)" means
that lsuc has connections to utcs, utcsri and utzoo, respectively.  Thus
if you see no easy connection between lsuc and "darwin(cz)", you can also
connect via lsuc!utcs!darwin.  And I believe you should be able to get from
any of the four U of T sites to any other of the four, so you can get from
lsuc to ms via lsuc!utcs!utai!ms.  The connections involving these four U of T
sites are summarized at the bottom.

Secondly, since this map is quite likely going to be used by people (like
me) trying to figure out how to get mail from mysite to yoursite, I have
tried to include only "good" paths.  A "good" path is basically either
HOURLY or better, or the only path there is, for machines with very few
connections.  I have also left out what looked to me to be "internal"
machines like hcrvx1, and represented the site only by its "external"
node hcr.  I don't personally think that internal machines should have
map entries in u.can.on.1 in the first place, but that's another issue.
I have also left off all the internal U of T sites, just because I haven't
figured out how to make a map for them yet.  I am still trying, and I'll
post it as a supplement when I figure it out.  Sorry folks.

Thirdly (this will be a shock), there are Errors in this map.  I'm sure
I don't have the most recent u.can.on.1, I'm sure that the most recent
u.can.on.1 has errors too, and I'm extremely sure that I wouldn't get
the whole map right the first time even if my u.can.on.1 was perfect :-).
(I even painted myself into a corner with my own machine: clunk has a good
connection to lsuc (as of a week ago), and I couldn't find a way to get it
on the map.  sniff)  But I would be more than happy to accept corrections
to this map and maintain it: this was FUN!  So look at your part of the
map and tell me where I goofed.  Maybe in the process we can even lick
u.can.on.1 into shape :-).

Okay, 'nuff said.  Presenting....
