Canada geese pairs mate for life, like other birds such as doves. They begin to nest in mid-February to late March. Their nests are made near bodies of water and are fashioned from sticks and grasses and lined with down feathers. Usually 4-7 eggs are laid which they sit on for 28 days. Ganders, the boy geese, are very territorial and help protect the female as she incubates the eggs. Once the eggs have hatched, both parents care for the goslings.
Canada geese are found in Canada (duh!) and the northern United States, but they will usually migrate to the South for the winter.
You can see them overhead flying in V-shaped formations. Why do they fly in this V-shaped formation? Is it aerodynamics? Is it leader of the pack pecking order syndrome? Is it so we can look up and go, "Ooooh!"
I don't think anyone knows for sure. Ask a goose and he/she will say, "Honk!"
I did look up one day from where I live now and tell my friends that there were some Canada geese overhead in a nice v-shape. I was quickly told that the birds in question were actually pelicans.
