Saw this in my newsfeed today - I thought this was previously released but perhaps not?

Gardeners will have an updated roadmap to help them plan next year as Natural Resources Canada has released an update to its plant hardiness zones map. The last map came out in 2014 and, since then, researchers say about 80 per cent of land in Canada has shown an increase in zones, typically between a half and a full zone. The new map, which came out in July, is based on data from 1991 to 2020.

Highlights include:
-GTA Average moving from 6A to 7A, perhaps due in part to the heat island effect
-Windsor moved from 7A to 7B, the first time that's been seen in Ontario
-Vancouver and Victoria have moved up to 9A (the scale goes to 9B)
-Calgary jumped from a 3A to 4A, Winnipeg jumped from 2B to a 3B
