Canada

Yes, I've seen these studies before. But even in this article:

The team found that, from a circadian perspective, we’ve made the worst choice. Either permanent standard time or permanent daylight saving time would be healthier than our seasonal waffling, with permanent standard time benefitting the most people.

(Emphasis mine)

Even just stopping the swapping is beneficial. And honestly, this study being "county by county" tells me that it is a US-centric study, which is primarily South of us in latitude and thus actually stands to benefit from a slight shift in the time.

However, in the depths of winter, we get sunlight from 10 am to 3 pm (ish) in my home province's chosen timezone. No 1 hour shift is going to give us "evening" sunlight. Shifting it by 1 hour at most gives us sun until 4 pm. Which means the people working until 4:30 or 5 (or later) are still going to work in the dark and coming home in the dark.

So I will reiterate, at this latitude, changing is not as meaningful. Changing the clocks in spring and fall is actively the most harmful option. So even if the "not-best" option is chosen, can we at least get away from the worst one? Please?
