Nobody wants permanent standard time. People want later daylight hours in the evening. All of the science behind it be damned.
Even this article, while stating the opposite conclusion, directly scientifically supports permanent daylight time as beneficial for most people.
It points out sunrise being at 0751 versus 0851 for Toronto. That's the anticipated sunrise time on 1 January 2027. The anticipated sunset time is 1651.
That means that someone working in a cubicle for a standard 0800-1700 schedule will get 9 minutes of possible daylight under winter time, versus 51 minutes under daylight time (sunrise 0851, sunset 1751).
Lack of sunlight leads to terrible circadian rhythms. There is absolutely zero scientific support for the proposition that nine minutes of daylight is healthier for our circadian rhythms than fifty-one minutes of daylight. No person could possibly argue such a thing in good faith.
(Also, I have a terminology quibble with "Standard Time," since Daylight Time is the actual standard, and we observe it eight months of the year.)
What possible meaning could the phrase "noon happens at noon" have? That's tautological and meaningless.
And if your solution requires a wholly independent, newly built mass coordination mechanism rather than just a minor tweak to the existing one, then I think the burden you bear for arguing your position is extremely high.
If we’re going to ignore the position of the sun, let’s just set a single “American time” to follow DC like China does and be done with it.
I am not interested in whatever you've got going on right now. Being dishonest about others' positions is bizarre. Refusing to clarify your own is bizarre. Let me know when you're willing to engage in good faith.
It used to, until people compromised on that for the sake of better societal coördination:
Conversely, getting up in the pitch dark and leaving the house in the pitch dark when the sun isn't going to rise for another hour is a horrible prospect and I hope I never have that inflicted on me. The evidence in the article is clear: our bodies need light in the morning more than we need it in the evening. Yes, winter sucks in northern latitudes, but we've just got to make use of the little daylight as best as we can. The flip side is by using DST we get these lovely long evenings in the summer.
Quite the entitled, unreflected comment. Not everyone works in an office or somewhere where this is a possibility!
From the published paper:
> Findings suggested that pDST and pST offered health advantages compared with the current twice-yearly clock changes, but the health benefits of pDST were lower than those of pST by a third. Notably, the comparative benefits of pST were greatest in northern regions of the continental US, which are similar to the latitudes in which most people in Canada reside.

Yes, there are benefits to pDST. There are more benefits to pST.
The reasoning the article takes to reach its incorrect conclusion is plainly erroneous. For example, it reasons that "Northern latitudes have later onset of winter sunrise and higher prevalence of SAD, with the latter increasing by 0.2% per 1° increase in latitude," ignoring that northern latitudes also have less sunlight overall.
It does not ignore the fewer hours: it prioritizes them towards the morning, where it is more important for circadian rhythm reasons.
It even mentions public dislike of the lack of morning light in the most recent large-scale pDST experiment in a northern-latitude country
> Russia moved to pDST in 2011. Public dissatisfaction grew rapidly, particularly in northern regions, where winter morning darkness was even more prolonged, with critics citing disrupted biological rhythms, morning travel risks, and effects on daily functioning. The policy was reversed in 2014.[15]

There are noticeable health effects on people even with-in a timezone depending on whether they live in the eastern or western part of it. For every 5˚ westward (~20 min later sunrise) you are, you have an increased chance of all types of cancer (n=4,000,000):

51-9=42 minutes difference, which is the equivalent to ~10˚ of longitude.

Standard Time dates back to the 1800s:
* https://en.wikipedia.org/wiki/Standard_time
The fact that it is eight months of the year has been true since 'only' the 2000s under Bush43 (I remember it not-fondly, given all the tzdata updates that had to be done at the time). DST was in the minority of the time the year previously.
With standard time you eat at 12 and with daylight saving you eat at 1, either way you eat when the sun is highest or around that time.
The thing is that the biannual dance of the clock hands wrecks any notion of time and schedules as this month you eat/wake up/leave work too early and the next too late.
34% of respondents in a Manitoba government poll wanted it:

I want it (in Ontario). Every chronobiologist and sleep research society wants it: see comments with link dumps on their position statements:
My entire household wants it.
It’s interesting for me because early morning means for me: dealing with duties (prepare for school, commute to work, etc) so I don’t really mind doing that in the dark. But afternoon time means for me: free time (school/work is finished ) So if there’s daylight I can decide to go to the park, or play outside, or go to a terrace to eat something. Doing that in the dark is just not feasible
Your circadian rhythm does not care about whether you are doing duties or fun stuff. It is being triggered/reset (or not) depending exposure to light. The more light you receive during the morning, post-wake-up, regardless of activity, the better your biology will run.
