Saskatchewan
Clocks in most of Saskatchewan are not changed and remain on Central Standard Time (CST) year-round, as required by The Time Act; It effectively acts as “permanent standard time” for most provinces.
The Battle River (Lloydminster) Time Option area follows Mountain Standard Time (MST) in the winter and DST in the summer, consistent with Alberta, meaning the clocks change there while the rest of Saskatchewan remains on CST year-round.

alberta
Observes DST under the current federal list. The clocks change from 02:00 Mountain Standard Time (MST) to 02:00 Mountain Daylight Time (MDT) on the second Sunday in March and back on the first Sunday in November.
No provincial exceptions are noted in the NRC table. (By April 2026, the province has announced plans to move to permanent daylight time, but the NRC table still reflects the standard DST regime.)

British Columbia
As of March 8, 2026, most of BC has adopted permanent year-round daylight time (“Pacific Time” at UTC‑7). The province last moved forward one time on March 8, 2026, and will not be moved back until November 1, 2026; This completes the transition to permanent DST.
Northeastern BC communities such as Dawson Creek, Fort St. John and Fort Nelson already observe MST (UTC‑7) year-round and continue to do so, effectively matching the new provincial Pacific Time offset. Southeastern communities in the East Kootenay and Golden regions continue to follow Alberta, switching between MST and MDT and therefore still observe seasonal DST.
Government of British Columbia, “Permanent Daylight Saving Time”; NRC Canada DST table (BC row – legacy pattern before 2026 change).
Yukon
Does not follow seasonal DST. Since November 1, 2020, Yukon has been on Yukon Standard Time at UTC‑7 all year; Residents “no longer have to change their clocks twice a year.”
This permanent time is equal to Pacific Daylight Time; The field no longer “falls behind” in autumn.

Northwest Territories
Observes DST. Follows Mountain Time with clocks changing from 02:00 MST to 02:00 MDT in March and to standard North American dates in November.
There are no specific regional DST exceptions listed in the federal table.

nunavut
Mostly observes DST. Nunavut spans three time zones (Mountainous, Central and Eastern); In all three, the clocks change at 02:00 local time on the second Sunday of March and the first Sunday of November.
Southampton Island (including Coral Harbor) remains on Eastern Standard Time throughout the year and does not change the clocks.
