For Naturally Shed Wildlife Parts
In Alberta, naturally shed wildlife parts, such as antlers, can be kept or sold without a special permit, as long as they were found outside of a provincial or national park or other protected area. 1. If you have found a skull, bone, or any other wildlife part that you are hoping to keep, contact the nearest Fish and Wildlife office.
2. If you plan to export naturally shed wildlife parts for sale or otherwise, please check to ensure wildlife laws in the receiving jurisdiction do not require permits or apply restrictions.
