The Ontario government announced plans to implement permanent Daylight Saving Time in northwestern regions located west of the 90th meridian, such as Kenora. This regulatory change aims to align these communities with Manitoba to prevent economic, social, and logistical disruptions.

Local officials and leaders from municipalities and First Nations have expressed support for the move. The alignment is intended to improve connections regarding healthcare, education, and business operations. While these northwestern areas will adopt permanent Daylight Saving Time, other regions in the Eastern Time Zone, including Thunder Bay, will continue to follow standard seasonal clock changes.
