Canada clock changes and local sunrise times

Canadian time rules are set by provinces and territories, with local exceptions. The familiar second-Sunday-in-March and first-Sunday-in-November pattern does not apply everywhere.

Most Saskatchewan communities use UTC−6 throughout the year, and Yukon uses UTC−7 throughout the year. British Columbia adopted permanent daylight time in 2026, with regional exceptions. Rules in western Canada changed during 2026; use the city’s current timezone status and next-change panel rather than a generic national date.

Every city shows the offset for the selected date and its next scheduled clock change. All sunrise, sunset and twilight times are already local; do not add another hour yourself.

Countdowns use actual elapsed seconds. The calendar changes offsets on the transition date, and daylight duration is calculated across the real local day. Future legislation can change the schedule, so the timezone version is shown on every city page.
