Nature

NatureCanada is the second largest country in the world. Since eighty-five percent of its population is located along its southern border, much of the country is wilderness.

Environment Canada manages nearly 12 million hectares of land as part of its duty to protect migratory birds, species at risk, and significant wildlife habitat. It also controls the international trade in endangered species, regulates the hunting of migratory birds, and conducts research on domestic wildlife.
