Barking Dogs

Persistent barking is not permitted at any time.

When a complaint is received about persistent barking, the complainant is encouraged to communicate with the owner of the dog. If that fails to produce satisfactory results, the By-law Enforcement Officer will speak to the owner of the dog and if that does not improve the situation, the By-law Enforcement Officer, with written evidence will issue a Provincial Offence ticket to the owner of the barking dog or assist the complainant to lay charges, which will necessitate a court appearance by the complainant.

Running at Large

Dogs must be on-leash at all times when off their property.

Dogs running at large may result in the owner being charged and/or the dog being impounded.

Animals in Hot Cars

If you see an animal in a hot car and are concerned the animal’s life is in immediate danger, dial 911. Members of the public should not attempt to enter a vehicle in these situations.  

  • Unlike humans, dogs have a very limited ability to sweat. Even a short period in a hot environment can cause suffering and distress, which could result in brain damage or death.
  • Excessive panting, drooling, listlessness, collapsing or seizures are all examples of visible signs of heat stress in animals. If you witness these signs in your pet, move the animal to a cool area and seek veterinary attention immediately.
  • Cruelty to any animal is not tolerated in Ontario. If you think an animal is in distress or being abused, call 1-833-9-ANIMAL (264625)
