Canada sees records fall due to unusually mild autumn, with one outlier
Much of the country enjoyed an unusually mild fall this year, another weather oddity that followed on the footsteps of Canada's warmest winter on record.
It isn't a surprise that many thought fall was pretty mild across the country, as it truly was for most areas.

In fact, multiple regions experienced their warmest fall on record, and for many others, it was mild enough to make it into the top five.
Many places in Northern Canada, northern Manitoba, northern Ontario and Quebec experienced their warmest fall on record.
Montreal, Que., was among the cities that recorded their mildest autumn on record, and was joined by smaller communities in documenting the accolade.
Among them were Alert, Resolute, Cambridge Bay and Rankin Inlet, Nvt., Churchill, Man., Kenora, Sault Ste. Marie and Kapuskasing, Ont., and Nain, N.L.
Meanwhile, several other places in Eastern Canada had their second-warmest fall. Among them are the Hamilton, Toronto and Ottawa airports in Ontario, and Fredericton, N.B. Charlottetown, P.E.I., meanwhile, observed its third-warmest fall on record.
The Prairies were looking good for an above-normal fall until the deep freeze took them out of the running in the last two weeks of November.
So, what was responsible for the atypical warmth seen during the autumn? A trend that helped delay Ontario's lake-effect snowfall until the end of November.
The pattern was conducive to bringing milder air in from south of the border, spreading it across Canada. But, even when we had chances to bring in air from the North, the air situated there was even mild. That anomaly led to Resolute and Alert seeing their warmest fall on record.
One region left out of the mild fall
The entire country, but one region, saw above-normal temperatures this season.
Southern Yukon, was a special case. It was the only region in Canada that saw below-seasonal temperatures.
It managed to record several instances with a northwesterly flow, and staying north of the milder air being pulled into B.C.
However, with that being said, it wasn't exceptionally cold by any means.
Whitehorse, Yukon, just finished -0.9 C below normal, a rather small anomaly compared to the 4 C and 5 C anomalies in Northern Canada.
