I have seen a Canada Goose sitting in front of a doorway of a business (a funeral parlor) and sitting in the parking lot. I am aware most geese are monogamous and have not seen it's partner. The site has a nicely maintained garden and lawn. Is there something I can do?
It might be injured, or just hanging out. You can consider contacting a wildlife rehabilitator at http://www.michigandnr.com/dlr/
