Alberta passes permanent daylight saving time law

The Canadian province of Alberta has passed legislation to adopt permanent daylight saving time, ending the practice of changing clocks twice a year. The change is set to take effect next spring, with the Northwest Territories also following suit with similar legislation, meaning most of Western and Northern Canada will remain on summer time year-round. Health experts have warned the move could disrupt circadian rhythms and increase the risk of seasonal depression, while business groups support it for better alignment with US markets and reduced scheduling confusion.
