P.S.
Switching to daylight time makes more sense in Eastern BC than it does in Western BC. But Eastern BC is relatively unpopulated. The population of Penticton is 40,000 vs 3,000,000 in metro Vancouver. Second largest metro (Victoria) is west of Vancouver.
Penticton experiences sunrise/sunset about 25 minutes before Vancouver, so their kids experience approximately equal amounts of sun before & after school on the winter solstice.
Penticton is also in a valley so in reality the sun goes behind the mountains in the west around 3:30PM.
I know exactly what you mean with your comment, but interesting fact, Vancouver is in the East of BC! BC is huge in both directions.
Even more so when you consider that most of metro Vancouver lives east of Vancouver city.
