You can find Canada Geese on almost any type of wetland, from small ponds to large lakes and rivers. However, Canada Geese spend as much or more time on land as they do in water.

Canada Geese breed in a wide range of habitats. They prefer low-lying areas with great expanses of wet grassy meadows and an abundance of ponds and lakes that serve as refuges from foxes and other land predators. The most northerly geese breed on the treeless tundra of the Arctic. Below the treeline, the geese nest in the open boreal forest, with its scattered stands of stunted spruce and tamarack. In southern Canada and throughout the United States, nesting Canada Geese are at home in many places, from sheltered mountain streams and prairie pothole ponds to golf courses and urban parks. During fall and winter, Canada Geese favour agricultural land where vast fields of cereal grains and other crops provide abundant food and relative safety from predators.
