Canada

In BC's case, we have passed legislation to move to permanent Daylight Saving Time... when Washington State, Oregon, and California do. The hold up is that US Federal law allows the states to stay on Standard time, and stop switching to Daylight Saving Time, but not the other way around. It has been before Congress a few years now, but the US isn't really good at getting things done, and this is low priority.

Technically we (BC) could just go ahead and do it. Or Washington, Oregon, and California could all just stick with Standard Time instead of Daylight Saving Time^1.

^1 I really don't care, PDT or PST. All arguments about "I like an extra hour of sun in the morning/evening" are pointless. The numbers are made up, and we can change start and end times. Do the kids need an extra hour in the morning for sleep according to the latest study? Set the school start times an hour later. Changing the clock against which all these times are measured is like changing rulers instead of using different measurements.

Ever notice how touristy places have seasonal hours? It's possible. Just stop changing the clocks instead of setting different times.

I have profound technical reasons to hate the time change. You know how you cell phone automagically changes the time? It's not magic, and it comes with technical consequences in Industrial Automation.

Also, large organizations. North America and Europe start and stop DST on different dates (thanks Bush). The northern and southern hemisphere start and stop DST in different directions. On top of that, most countries don't change the clocks. There's a reason you'll see references to UTC on the Internet.
