In Canada, the OSPCA can go to the door to make inquiries. It is up to the owner to let them search the animal area without a warrant. If from the road the inspector sees horses/animals in need, a search warrant has to be obtained to inspect the animals. The owner will be given a written order outlining the care the animals need and a deadline. If an animal is in dire straits it will be seized, otherwise there is a followup. Should the order not be followed the person will have to appear in court and will face a fine.
