Hey cajun dude, hunting Canadian geese is not illlegal everywhere. We have month long seasons on them here, 2 of them. They also issue damage permits because they are becoming such a nuisance. Every so often the USDA will slaughter thousands of them because there's just too many. I have a friend who works for the USDA and he actually got tired of slaughtering so many of them, LOL. Paid for by our tax dollars, instead of just opening the seasons up more.
But there most certainly is season on them here in IL, as well as IA, and NY. (States I've lived in). A simple google search of goose hunting regulations should show you the info.
