More Canadians to observe permanent daylight saving time. Why can’t the US?

Several Canadian provinces have moved to remain on daylight saving time throughout the year, so a growing number of residents will not turn their clocks back by one hour when Canada’s clocks normally change in November. The provincial shifts mean communities will keep later evening light in winter months and avoid the biannual clock change. The changes reflect provincial decisions rather than a single nationwide switch, so implementation and local effects vary across the country. For residents in jurisdictions that adopted permanent DST, the familiar autumn adjustment will no longer occur, altering routines tied to sunrise and sunset times. The development also underscores a policy difference with the United States. Under current U.S. federal rules, states cannot unilaterally adopt permanent daylight saving time without congressional approval, which has limited their ability to mirror Canada’s move to year-round DST. As more Canadian provinces commit to permanent DST, the result is increased cross-border complexity for scheduling, transportation, and commerce in regions that remain on seasonal time changes. The choices by provincial governments will shape daily life and coordination with jurisdictions that maintain the biannual clock shifts.
