The Town of South Bruce Peninsula appealed its conviction for damaging Piping Plover habitat under the Endangered Species Act, 2007.

The appeal raised issues regarding the interpretation of "damage" under the Act and the admissibility of expert evidence from a Ministry biologist.

The Court of Appeal dismissed the appeal, upholding the lower court's interpretation of "damage" as including actions that make habitat less attractive, useful, or valuable from the species' perspective, and affirming the admissibility of the expert's evidence, despite concerns about impartiality, as the trial judge's decision was entitled to deference and the evidence of another expert was sufficient.

The proposed interveners, Environmental Defence Canada Inc. and Federation of Ontario Naturalists, sought leave to intervene in an appeal concerning the statutory interpretation of s. 10(1) of the Endangered Species Act, 2007, which prohibits damage to habitats of endangered species.

The Town of South Bruce Peninsula opposed the intervention, arguing it would not offer a useful contribution.

The court granted leave to intervene, finding the matter to be of public interest with broad implications, and that the interveners, as reputable environmental organizations, could offer a unique and useful perspective on the interpretation of "damage" and the application of principles like de minimis and the precautionary principle, without causing injustice to the appellant.
