Canada's hot spot was in the Prairies on Sunday, but southern Ontario wasn't far behind. Windsor climbed to nearly 27°C.
Although light showers could appear in southwestern Ontario on Monday, the holiday is expected to be mostly dry across southern parts of the province.
That will cap off a long weekend of fantastic weather, perfect for apple picking at Chudleigh's in Milton and celebrating Oktoberfest in Kitchener-Waterloo.
The Weather Network's Chris St. Clair is judging floats in the Thanksgiving Day parade at Oktoberfest.
Mittens won't be a necessity along the parade route this year. But fall accessories are starting to come in handy, especially at night or in the early morning as temperatures nosedive. Some parts of southern Ontario woke up to frost on Sunday morning before the day warmed up.
With temperatures swinging between warm and cool, how much longer can the mild weather last?
“Fall is definitely a transitional season between the summer and the winter. We get a lot of fluctuation in the jet stream as it's trying to fall into the winter pattern,” says Dayna Vettese, a meteorologist at The Weather Network.
“So we definitely going to see some more warm spells, and some cool spells, before the temperatures finally cool off for the winter.”
