This is a contentious topic because switching the clocks is a tradition that marks the change in season and people are psychologically bonded to it.  But, I believe it's very important to listen to the folks with actual data on the subject. There are a lot of disruptions and costs associated with changing the clocks twice a year.  Add to that the reality that we already enjoy daylight savings time for most of the year and standard time for only about 1/3 of it.  I'm sitting here in Calgary at 8 am, in the dark, ready to go to work; by 6 pm I'll be coming home and it will already be nearly dark.  Going back to standard time this weekend will make a only small and temporary difference.  Canada is a northern nation and switching back to Standard time makes less sense here than in the south.  The article notes a preference for staying on DST all year.  I would agree.
