Another option for the name that I haven't seen discussed is "PDT". Washington, Oregon, and California, are big populations that do have ties with BC, aligning with their name for the majority of the year might be more useful than aligning with Alberta's name for just 4 months of the year.
Also keep in mind that the BC government's press release is titled "Adopting permanent daylight saving time" and they want it to be called Pacific time.
