For practical purposes, Canada has adopted the American hardiness zone classification system. The 1990 version of the USDA Plant Hardiness Zone Map included Canada and Mexico, but they were removed with the 2012 update to focus on the United States and Puerto Rico. [8] The Canadian government publishes both Canadian and USDA-style zone maps. [37]
In 1967, Canadian scientists created a map outlining Plant Hardiness Zones. The hardiness zones examine climatic gradations such as length of frost-free period, summer rainfall, maximum summer temperatures, minimum winter temperatures, and wind speed. The harshest plant environment is 0 and the mildest is rated as 8.

Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand.
According to the new map released in November 2023, about half of the United States has shifted to a new hardiness zone. That's really big news if you consider 80 million Americans use this map to ...

It includes the Canadian portion of the Great Plains and the Prairie provinces, namely Alberta, Saskatchewan, and Manitoba.

Horticulture which includes garden crops, and fruits became easier to grow with the development of plant hardiness zones. [32] In Saskatchewan, the main horticultural products would be potatoes (for seed and commercial sale), small fruits, vegetables, fresh and dried flowers greenhouse production, sod operations, and nursery operations.
