TZDB 2026b, released 2026-04-22, already has the BC change.

Unfortunately it may take some time for this to percolate into Workday,
as Workday uses Java which depends on CLDR for localization of the new
time zone, and as I understand things CLDR doesn't plan to have
localization fixes until mid-October. So at least localization, and
perhaps timestamps, probably will not work until this is sorted out.

I assume Java will be fixed soon after CLDR is fixed, and Workday will
be fixed soon after that. So it'd be wise to monitor these fixes during
October, and to take care when using Workday before October to schedule
events after October, as today's Workday may mishandle the times of
events scheduled after October in BC.

One more thing. We plan to issue a new TZDB release soon, for a similar
change planned for Alberta. And there quite possibly will also be
similar changes in Northwest Territories and in Nunavik though this has
not been legally confirmed yet. These other changes have issues similar
to the BC change, for applications like Workday.
