Well, Canada is a VERY wide country. We have 4.5 time zones across the country, and BC itself is as wide as Germany.

There are several regions along the border between BC and Alberta that already eliminated daylight savings time years and years ago, so they were on a different time zone for half the year.

E.g. the Peace River Region
