In Canada you can parody anyone. For example Justin Turdeau instead of Justin Trudeau (leader Liberal party Canada). It's funny and you can't get sued never mind have the police come after you. It's called freedom of speech.
Legally, yes; but none of that kicks in until after some sort of legal proceeding actually occurs. If the cops just break down your door, shoot your dog, and seize everything that looks evidentiary and/or worth 'losing', and then no charges are filed? Well, if you have the resources to lawyer up, you could probably make a civil case out of it; but otherwise you just got protected and served.
