BC, Alberta and Manitoba Stop Changing Clocks: What It Means

On November 1, 2026, clocks in British Columbia, Alberta and Manitoba did not fall back. All three provinces now stay on their old summer time all year: Vancouver at UTC-7, Calgary and Edmonton at UTC-6, Winnipeg at UTC-5. Ontario, Quebec and the United States still change clocks, so every winter gap between the west and its neighbours has shifted by an hour.

What changed and when

The spring forward on March 8, 2026 was the last clock change in all three provinces. Nothing happened to the time on the wall after that. What changed on November 1 is that the usual fall back was cancelled, so the summer offset simply carries on through the winter and into every year after.

British Columbia went first. Its government announced on March 2, 2026 that the March 8 spring forward would be the final one and that Pacific time would be set at UTC-7. Alberta followed with what it calls Alberta Time, UTC-6, and Manitoba with Manitoba Standard Time, UTC-5. The tz database (the shared time zone data behind phones and computers) records the legal dates as March 9 for BC, June 18 for Alberta and October 31 for Manitoba. None of those dates moved a clock.

Two neighbours went the same way. According to the tz database, the Northwest Territories moved to permanent UTC-6 on August 21, matching Alberta, and the parts of northwestern Ontario that have long kept Winnipeg time were allowed by provincial regulation to stay with Manitoba. Yukon has been on UTC-7 all year since 2020, so it now matches BC year-round. Saskatchewan never changed its clocks and still doesn’t; its new Time Act, 2026 came into force on October 30 without any change to the hour.

The new year-round offsets

The zone pages show the same data with the full history: America/Vancouver, America/Edmonton, America/Winnipeg and America/Regina.

Permanent daylight time or standard time?

Both, depending on who is talking. The clocks stayed on the summer offset, which is why news coverage calls it permanent daylight time and why the BC and Manitoba governments use the same phrase. Officially, each province gave the year-round offset a new name and made it its only time; Manitoba even calls it Manitoba Standard Time. Software sees it the same way: a clock that never changes has no daylight time to save, so the tz database files it as standard time.

That leaves four sets of names for the same three offsets:

The tz database picked labels that already exist for each offset in North America. UTC-7 all year has always been written MST in Arizona, Yukon and Dawson Creek, so Vancouver now shows MST too. The catch is that these labels describe an offset, not a region. A phone in Vancouver may display “MST” while the province calls it Pacific time, and a Calgary laptop showing “CST” is not on the same clock as Chicago in summer, when Chicago moves to CDT (UTC-5). Our advice: in invitations and messages, write a city or a UTC offset (“10:00 Vancouver, UTC-7”) and skip the three-letter code. The time zone abbreviations guide covers the other clashes.

Whether permanent summer time beats permanent standard time is a separate argument about sleep and winter mornings. It has its own article on the permanent DST debate, and the background on clock changes in general is in our daylight saving time guide.

New winter time differences

In summer nothing moved: the western provinces were already on these offsets. The difference shows up from November to March, when the United States, Ontario and Quebec fall back and the west stays put. Each western province is now one hour further ahead of its US neighbour in winter than it used to be.

London runs on its own calendar: it is on GMT from October 25, 2026 to March 28, 2027, so the 7-hour gap starts and ends a couple of weeks away from the US dates. A worked example: at 6:00 p.m. in London on December 15, it is 11:00 a.m. in Vancouver and 10:00 a.m. in Seattle. Last winter, Vancouver would have shown 10:00 too.

Will my phone and calendar get it right?

Phones and computers take their rules from the tz database, which added BC in release 2026b (April), Alberta in 2026c, the Northwest Territories in 2026d and Manitoba in 2026e (September 29). A device that received an operating system update after the relevant release kept the right hour on November 1. One that did not would have fallen back by itself and is now an hour behind.

There is one quirk in the data. To work around limits in Unicode CLDR and ICU, the libraries that format dates in many apps, the tz database places each province’s switch on November 1 at 2:00 a.m. rather than on its legal date. The UTC offset is the same either way, so only the label changes on that date.

Calendars are the more common trap. Manitoba’s guidance warns that events created before the update, and meetings sent between different calendar platforms, may show an hour early or late. Open your next few recurring meetings and check them against the current time in Winnipeg, Calgary or Vancouver on our city pages. The reasons a phone clock can be wrong at all are in why your phone clock is right.

Exceptions inside the provinces

BC has never been one clock. The Peace River region and the northern Rockies (Dawson Creek, Fort St. John, Fort Nelson, Chetwynd, Tumbler Ridge and nearby communities) already kept UTC-7 all year. They now match Vancouver every day of the year without changing anything.

The East Kootenay and Golden region (Cranbrook, Fernie, Invermere, Kimberley and others) follows Alberta. BC’s March release said those communities would stay aligned with Alberta, and the tz database maps them to America/Edmonton, which is now UTC-6 all year. Local governments in BC keep the power to choose their own time, so if you live there, confirm with your municipality. A western sliver of Saskatchewan also keeps Alberta time, which now matches the rest of Saskatchewan all year.

What it means for meetings and travel

Cross-border recurring meetings are where people get caught. A Seattle team’s 9:00 a.m. Pacific standup used to start at 9:00 in Vancouver all year. From November 1 to March 14 it starts at 10:00 in Vancouver. A 1:00 p.m. Eastern call set in Toronto now lands at 11:00 a.m. in Vancouver instead of 10:00. A good calendar handles this on its own only if the event is anchored to the organizer’s zone and both sides have current data.

1. Set recurring meetings in one named zone (America/Vancouver, America/New_York), not a fixed offset.
2. For the winter months, compare the slot in the time zone converter for a date in December, not today.
3. Add the other team’s city to the world clock so the shifting gap stays visible.
4. Recheck in mid-March 2027, when the gaps snap back to their summer values.

Until March 14, Calgary keeps Chicago’s hour and Winnipeg keeps New York’s, so check any booking made before the change. Other offset changes from this year, including Morocco’s, are in recent time zone changes. Then open your first cross-border meeting of December in the converter and fix the invite in the organizer’s zone.
