But standard time gives different hours based on your lat/long position. Eastern has about 45 min later daylight, western has 45 min earlier sunrise. So one standard doesn’t give all provinces the same daylight range, it is shifted
I mean in Vancuver BC longest summer, official daylight is 5:05am, but twilight is 4:23am. Toronto daylight in longest summer day starts about 5:35 (twilight at 5am)
The twilight here is super bright. East coast gets more daylight in winter I think
The eastern part of a time zone has earlier sunrise/sunset than the western part of that same time zone. A little past Detroit would have Vancouver times.
Maybe winter, but if you check longest Sumner day as a common point, Vancouver has earlier sunrise by 25-30 minutes, and earlier twilight by 40…compared to detroit. I have lived in both areas .
It is also not just about the time zone positions laterally because the sun shadow is at an angle compared to longitude due to precession angle I assume. If you lookup sunshadow animations you will see what I mean.

Standard time is better for the health of the population, especially in teens. There’s a ton of research on the subject.
