Thank you for the question.
The only section of the Criminal Code that could be used to prosecute someone for killing a law enforcement animal, a police dog, was section 445.1, which covers cruelty to animals
That was the section used to prosecute Quanto's killer. That's pretty much all I can say on the matter.
The case law does not allow us to analyze previous cases because the nature or role of the killed or injured animal is not specified in section 445.1.
