Canada's Plant Hardiness Zones
Canada's plant hardiness map provides insights about what can grow where. It combines information about a variety of climatic conditions across the entire country to produce a single map. The original map was developed in the 1960's for trees and shrubs. We have produced several updates to this map using extensive climate data and modern interpolation techniques.

- Details on plant hardiness calculations
- Plant Hardiness Zone by Municipality
