Daylight Saving Time and sunrises

When they were talking about changing daylight saving time in 2007, my primary concern (which wasn't one that seemed to get much in the way of media attention) was that more people would have to wake up in the dark and start work and school in the dark, which would mess with our circadian rhythms.

That concern went unheeded, and daylight saving time changed despite my protests.

I've been struggling to drag myself out of bed these past couple of weeks (yes, even with my work-from-home schedule), and, with some googling, I realized it's because sunrise is even later than it is at winter solstice!

Just before daylight saving time starts, sunrise here in Toronto will be at 7:59 AM.

But the latest it gets in December is 7:51 AM.

Even if there are in fact good reasons for extending daylight saving time, there is no excuse whatsoever for making even later than it is in the bleak midwinter. If it absolutely must be a certain number of weeks, they should make it start earlier in the spring, resulting in a sunrise time of 7:30-7:40.  But the latest natural winter sunrise time should be a rubicon that is never crossed.
