I did copy Samuel Wat, the original author of CBC's Nunavik reporting last
year, on a recent list message for his general awareness about our
understanding of the situation there.  But they would of course have to go
through their own research process before reporting out any updates.

The various upcoming municipal elections in many of the areas we're
watching (British Columbia on 17 October, Ontario on 26 October, Manitoba
on 28 October) certainly add an interesting dimension to all of this, but
one that I think we'd rather avoid engaging with directly wherever
possible.  It may just be that we have to wait for the dust to settle and
then call around the area asking "what time is it there?" as has been done
at a few points in the not-so-recent past.

In particular, at this late juncture, I am definitely not inclined to react
by hastily making new zones that may not end up being needed once things
actually shake out in *de facto* practice come 1 November.  The safest
thing to do in the interim seems to be to assume (albeit likely
incorrectly) that all relevant portions of northwestern Ontario will follow
Winnipeg, while any regions that don't can employ workarounds by using
America/Chicago or America/Toronto as may be appropriate in the meantime.

The sheer number of potential jurisdictions involved, and the rapidity with
which they will either need to make decisions or not, starts to evoke the
guidance on "[if] boundaries between regions are fluid" in theory.html:

It also so happens Paul and I both have a busy week this week — certainly
not the biggest reason we advise 6–12 months' notice, but not a total
non-factor either!  😅  But it's also why we're not likely to be able to
reach out proactively to more than a handful of key jurisdictions beyond
whatever traditional media may be able to help synthesize in the meantime.

While the data fix itself for Manitoba is of course straightforward,
documenting it and all of the potential knock-on effects comprehensively
enough in a way that is both suitable for release and resilient to whatever
may come next has been a fair bit more involved.  Proposed patch attached,
and installed in the development repository.
