That way you you don't have to deal either with the sun beating down on you while you try to sleep at 4am or with your poor children getting run over in the dark on their way to school.
In the summer, the sun still rises around 4:30AM with daylight saving time. I don't see how 3:30AM or 4:30AM makes much of a difference. And it sets at 10PM or 11PM. Either way it doesn't make much of a difference. Or to put it, "the juice isn't worth the squeeze". Because you just get that daylight for another couple of weeks and then it's back to darkness or daylight again. And I'm close to the US border.
And then we get close to winter and the sun doesn't rise until 9AM so your kids are still going to school in the dark. And then starts setting right when they get dismissed. It's not unusual for it to be light when they leave school, then darkness when they get off the bus 40 minutes later.
The US states that did do it were more mid-latitude states where it's not a bad idea. But in Canada, it's likely to not make much of a difference because in the summer it's been out for hours at 6AM (daylight time) and in the winter it's still dark when you drop the kids off at school (standard time) or head into work.
Anyhow, if there needs to be a transition to standard time, going from daylight to standard time is generally much easier than the other way around. Just stop screwing with the clocks.
I don't care if the clocks auto-set. Not being sure about the current time (did this clock change?) is way more damaging than having to adjust clocks. There used to be clocks you can call to get the current time, but those died out decades ago. Now you're just not sure. Even public clocks aren't always right - there are plenty of clocks I run into still using the old daylight saving time schedule, decades after Dubya changed it. They're off for a couple of weeks until they change. And no, you can't check on the internet because most of them just use the current system time.
