I vote 100% with Ron in Regina on this, possibly because I too am in Regina. I see no value in switching time twice a year (too @#@#$ many clocks to reset in my house), and every argument but one I've ever seen in favour of it is easily dismissed as nonsense. That one is the longer period of light in summer evenings. In the deep winter, when it's light for such a short time anyway at these latitudes, it really doesn't matter, you're going to be going to work in the dark and going home in the dark, so it seems to me that if we're going to change times around, the sensible thing to do is to "spring forward" once and leave it there.
Part of the problem, really, is just the way time zones are laid out. Time zones are 15 degrees wide, so 24 of them make a full circle, and they start at the 0 meridian at Greenwich, near London. The meridian at 105 degrees west of Greenwich should thus be the boundary of a time zone, 7 hours behind Greenwich. That line runs almost precisely down the centre of Saskatchewan, and no matter what time zone the province adopts, some people on the far east side or the far west side of the province are going to be unhappy about the time because it shortens their summer evenings. But if you look at summer sunrise and sunset times in Winnipeg, Saskatoon, Regina, Edmonton, and Calgary, they don't differ by more than a few minutes, and there doesn't seem to be any ferment in Manitoba or Alberta about the length of summer evenings. Tempest in a teapot if you ask me.
