The Canada Goose (Branta canadensis), colloquially Greater Canada or Canadian Goose in North America, belongs to the Branta genus of geese, which contains species with largely black plumage, distinguishing them from the grey Anser species. The species name, canadensis, is a New Latin word meaning "of Canada".

The black head and neck with white "chinstrap" distinguish this goose from all except the Barnacle Goose, but the latter has a black breast and grey, rather than brownish, body plumage. There are 7 subspecies of this bird, of varying sizes and plumage details, but all are recognizable as Canada Geese. Some are hard to distinguish from the Cackling Goose (Branta hutchinsii), with which the Canada Goose was long assumed to form one species, and the name Lesser Canada Goose is, confusingly, often applied to B. hutchinsii.

This well-known species is native to North America. It breeds in Canada and the northern USA in a variety of habitats. However, the nest is usually located in an elevated area near water, sometimes on a beaver lodge. The eggs are laid in a shallow depression lined with plant material and down. Males, 8–14 pounds (3.5–6.5 kg), can be very aggressive in defending territory. A pair may mate for life (around 20 years). The female looks virtually identical but is slightly lighter (7–12 pounds, 3–5.5 kg), and has a different honk. Adult geese are often seen leading their goslings in a line with one parent at the front, and the other at the back of the "parade".

Like most geese, it is naturally migratory, the wintering range being most of the USA. The calls overhead from large groups of Canada Geese flying in V-shaped formation signal the transitions into spring and fall. In some areas, migration routes have changed due to changes in habitat and food sources. In mild climates, such as the Pacific Northwest, due to a lack of former predators, some of the population has become non-migratory. Some migratory populations in temperate climates frequent cities as well, due to convenient, predator-free open spaces. These birds are considered by many to be a nuisance, mainly because of the large volume of feces they produce, and like other water fowl , they also frequently walk with their young across roads, creating traffic tie-ups. Some cities have begun extermination programs against them. Other solutions have included relocation, and the use of a substance to coat the eggs to prevent maturation and hatching. Many geese are also killed in collisions with automobiles and occasionally aircraft.

Canada Geese have reached western Europe naturally, as has been proved by ringing recoveries. The birds are of at least the subspecies parvipes, and possibly others. Canada Geese are also found naturally on the Kamchatka Peninsula in eastern Siberia, eastern China, and throughout Japan.

Greater Canada Goose has also been widely introduced in Europe, and have established feral populations in Great Britain, The Netherlands and Scandinavia. Semi-tame feral birds are common in parks, and have become a pest in some areas. Interestingly, it is now proven that most Scandinavian and some British birds have established a migration pattern. The geese were first introduced in the United Kingdom as an addition to King James II's waterfowl collection in St. James's Park.

These birds feed mainly on plant material. When feeding in water, they submerge their heads and necks to reach aquatic plants, sometimes tipping forward like a dabbling duck. Flocks of these birds often feed on leftover cultivated grains in fields, especially during migration or in winter. They also eat some insects, molluscs and crustaceans.

By the early 20th century, over-hunting and loss of habitat in the late 1800s and early 1900s had resulted in a serious decline in the numbers of this bird in its native range. The Giant Canada Goose subspecies was believed to be extinct in the 1950s until, in 1962, a small flock was discovered wintering in Rochester, Minnesota by Harold Hanson of the Illinois Natural History Survey. With improved game laws and habitat recreation and preservation programs, their populations have recovered in most of their range, although some local populations, especially of the subspecies occidentalis, may still be declining. They have adapted well to urban environments, especially those with well-trimmed lawns and large ponds, such as golf courses and city parks.
