An added wrinkle is that parts of British Columbia use other timezones.

The southeast corner follows Alberta time (previously MST/MDT but changing to MDT).

Parts of the northeast and iirc a few other communities (eg Creston) have historically followed MST (no switch) and will now be effectively on the same time as Vancouver, albeit probably with a different TZ designation(?).

The East Kootenays still hasn't decided what timezone to align with. They used to align with Alberta (w/ daylight savings switching) as well. Then B.C. announced their change and the East Kootenays announced they were aligning to Pacific Daylight Time, which meant for the East Kootenays only uniquely "falling back" an hour a final time this fall. Then the East Kootenays rescinded that decision, and since then, Alberta has announced permanent daylight time. Now they need to decide which to align with.

The current plan is for the East Kootenays (America/Cranbrook) to "fall back" to PDT this fall, but IANA TZ database still hasn't made the update because of the uncertainty.
