First Day Of Winter 2024 Canada. In canada, the winter solstice usually falls around december 21st. The 2024 december solstice takes place on december 21, at 9:21 utc.

It marks the northern hemisphere’s shortest day (first day of winter) and southern hemisphere’s longest. October could very well deliver some winter weather, but we do not expect that cold weather will lock in until later in november or december.
