The thrust of EC's mandate is to improve the quality of life of Canadians through the preservation and enhancement of the natural environment, including water, air and soil quality, renewable resources, migratory bird and other wildlife, as well as weather forecasting and warnings. The mandate also includes addressing decisions and recommendations of the Canada-U.S. International Joint Commission which deals with boundary waters and coordinating federal environmental policies and programs.

EC's science and technology (S&T) is organized in three program activities:

• atmospheric environment;
• environmental protection; and
• environmental conservation.

It is conducted through three mutually reinforcing business lines:

• reducing risks to human health and the environment;
• weather forecasts and warnings and emergency preparedness services; and
• giving Canadians the tools to build a greener society.
