Yukon already changed to permanent daylight time in 2020, and Saskatchewan stopped changing clocks decades ago. These moves have reshaped Canada’s time‑zone map.

A small area of northwestern Ontario, including the city of Kenora, currently follows Manitoba’s time instead of the rest of Ontario.

When Manitoba’s permanent daylight time takes effect, that part of Ontario will be the only region in its own time zone during winter. It will be one hour behind Thunder Bay to the east and also one hour behind Winnipeg to the west.

People living there will need to adjust work hours, school schedules and travel plans. Businesses that deal with Ontario or Manitoba will have to remember the one‑hour difference in winter.
