"Are Canada Geese protected and can they be hunted?

Yes, Canada Geese are protected under the Migratory Birds Convention Act, 1994 (MBCA). This Act arose from an international treaty -- the Migratory Birds Convention -- between Canada and the United States, signed in 1916. The MBCA provides for the protection and conservation of migratory birds, and prohibits people from harming birds, except under specified conditions. Several species, including Canada geese, are considered game birds and may be hunted. The Act gives the federal government the responsibility to establish hunting seasons, and Canada Geese are greatly appreciated by migratory game bird hunters across the country. More than 500 000 Canada Geese are taken in Canada each year by hunters." [1]

Canadian geese are pretty tough to bring down. My dad has been hunting them on the St. Lawrence for the last 25 years. Since they outlawed lead shot, there are a lot more geese that get shot and limp off, rather than come down. The various new bismuth and other heavy shot types work a little better than steel, but are very expensive.

Goose is also kind of an acquired taste. Some people don't like it, as it is kind of gamey, and if you don't know what you're doing it is pretty easy to over-cook it and turn it into shoe-leather.

Not necessarily tasty. The non-migratory geese taste like ass.
