Standard Time was initially established in such a way, in the middle of the zone, noon is mid-day, meaning sunrise at 7am means sunset at 5pm.
On Summer Solstice Day, June 21, in Toronto, sunrise at 5h36 and sunset at 21h02. If we were in standard time, sunrise would be at 4h36 and sunset at 20h02 instead. Take away that wasted natural morning light hour and move it to the evening, instead of wasting electricity while the town is alive. On the other hand, evenings are hot, and therefor, we use air conditionning for a longer time.

On Winter Solstice Day, December 21 in Toronto, sunrise at 7h47 and sunset at 16h43. If we were in daylight savings time, sunrise would be 8h47 and sunset at 17h43 instead. Longer house heating in the morning, drive to work in the dark, and it's still dark if you shift starts at 8am. More office heat required due to colder morning temperature...
The way most of us live since the 1960s, it's morning not before 6am, and sleep past 11pm, so daylight savings year round makes sense.
We had a good run: 2006 to 2020. Thanks for the informations and debates.
