Much of eastern Canada will turn their clocks back one hour on Sunday, marking the start of standard time, while western provinces will remain on daylight saving time. The change affects provinces such as Ontario, Quebec, and Atlantic Canada, but not British Columbia, Alberta, or Saskatchewan.

The decision to adjust clocks follows the federal government’s annual review of daylight saving time policies. This year’s adjustment aligns with previous years, with the eastern time zones shifting back to standard time. The change is expected to impact daily routines, energy consumption, and travel schedules.

Daylight saving time in Canada has been a topic of debate for years, with some provinces advocating for year-round daylight saving. However, the federal government has not yet made any permanent changes to the policy. The current system divides the country into two time zones: eastern and western, with different rules for adjusting clocks.

The time change occurs simultaneously with similar adjustments in the United States, though not all states participate. The shift is typically observed in late March or early April, depending on the region. Residents are advised to update their clocks and adjust their schedules accordingly.

The practice of changing clocks has historical roots, originally intended to conserve energy by extending daylight hours during spring and summer. While some studies suggest potential energy savings, others argue the impact is minimal. The debate continues, with no immediate plans for nationwide reform.
