Climate
Boreal shield
The climate in this ecozone is generally continental. The Great Lakes have moderating influence on weather conditions in central Ontario. Regions bordering Atlantic Ocean tend to have a more humid, maritime climate.Cold air masses over Hudson Bay largely influence climate and bring high levels of precipitation to the area.
There are generally long, cold, winters and short, warm summers in the Shield. The average midwinter temperature is -15ºC, and the average midsummer temperature is around 17ºC.
The largest ecozone in Canada, the Boreal Shield covers 1.8 million square kilometres and is roughly 3,800 km long. It stretches from Saskatchewan to the very tip of Newfoundland and Labrador. Although it houses only about 10% of Canada’s population, it is one of the most important economic areas in Canada due to the large lumber and mining industries.

The Canadian Shield, which makes up most of
the Boreal Shield, was once an ancient Precambrian mountain range formed by the
buckling and cracking of plates. Some of the oldest rocks in the world can be
found here, dating back to as early as 3.96 billion years ago.
