I just checked my machine running macOS 26.5 Tahoe, which seems to have
received tz 2026b as an update early Wednesday, though I have not yet done
the "manual restart" to apply it. As such, I can compare them directly and
confirm that, for Canada, this only contains the BC changes we've published:
/private/var/db/timezone/tz % diff -r {2025c.1.0,2026b.1.0}/zoneinfo/America
Binary files 2025c.1.0/zoneinfo/America/Vancouver and
2026b.1.0/zoneinfo/America/Vancouver differ
Ng's comment implying that the update includes or is prompted by Alberta's
more recent actions was an incorrect (but well-intentioned) assumption or
simplification, given it took ~5 weeks for Apple to propagate BC's changes.
