The two major Canadian cities that fall outside the continental climate schema are Vancouver and Victoria. Vancouver experiences an oceanic climate, bordering warm-summer mediterranean with a marked summer dry season. Victoria, BC is the only major Canadian city entirely in a warm-summer mediterranean climate.
In 2014, the Canadian Council on Ecological Areas (CCEA) released an update to the first digital version of the Canadian Ecological Framework (CEF). The new spatial framework was designed to replace the 1995 ecological framework as well as the Ecozone+ framework used in the Canadian Biodiversity: Ecosystem Status and Trends 2010 Report.
The climate and ecology of different locations on the globe naturally separate into life zones, depending on elevation, latitude, and location. The generally strong dependency on elevation is known as altitudinal zonation : the average temperature of a location decreases as the elevation increases.
Climate is a major barrier to life; the growing season is extremely short. Mean average temperature usually ranges from 0 °C (32 °F) to 4 °C (39 °F), and even in summer the average temperature does not exceed 10 °C (50 °F). The zone sees heavy precipitation, usually in the form of snow. [3]
Because of its location east of the Rocky Mountains, the Prairies ecozone can be semi-arid in some areas, annual precipitation generally increases farther east in the ecozone from 250 millimetres (9.8 in) in southern Alberta and Saskatchewan to 700 millimetres (28 in) in parts of Manitoba, as well humidity increases eastward through this zone.

Rainfall in the Canadian Arctic has increased by more than 20% in the last decades. However, the degree of rainfall increase is subject to variation from one location to the next. For example, in Resolute, Nunavut in the period of 1948 to 2007, there was a 48% increase in rainfall recorded with an average of 13.6 mm (0.54 in) of rain per decade.
Temperatures here are similar to the semi-arid climate zone, but this region is the most humid area in the Prairie Provinces with moderate precipitation. [ 2 ] Southwestern Manitoba, though under the same climate classification as the rest of Southern Manitoba, is closer to the semi-arid interior of Palliser's Triangle , and as such, is drier ...
The climate of Ontario varies by season and location. [19] It is affected by three air sources: cold, dry, arctic air from the north (dominant factor during the winter months, and for a longer part of the year in far northern Ontario); Pacific polar air crossing in from the western Canadian Prairies/US Northern Plains ; and warm, moist air from ...
