The main purpose of this legislation is to change the rules regarding the importation of polar bear trophies taken from sport hunts in Canada. Specifically, it aims to allow individuals to bring back trophies from polar bears that were hunted legally before these animals were classified as threatened under the Endangered Species Act. Key provisions of the legislation include the requirement for hunters to provide proof that the polar bear was legally harvested either before February 18, 1997, or before May 15, 2008, from specific populations that were eligible for trophy importation.
