There's a whole lot of bad information in that very short post.
First, Geese did not originate in MN - the were domesticated in Egypt 3000+ years ago, and are believed to originate in Europe and Asia (source: http://www.fao.org/docrep/005/Y4359E/y4359e03.htm
Second, there is no such species as Canadian Geese. They are called Canada Geese. Common mistake, though. (source: http://www.worldbirdnames.org/n-waterfowl.html
Third, virtually all migratory geese, including Canada Geese, fly north in the spring, and south in the winter (but many geese do not migrate at all, having no natural predators and plenty of food in their year-round habitats). (sources: http://en.wikipedia.org/wiki/Canada_goose
So yeah, looks like even with the interwebz at hand, maybe some Northern Inland folks are a bit confused about geese....
