Physician's office reporting - a patient bitten by an animal

City of Toronto, Municipal Code, Chapter 349 defines a bite as piercing or puncturing of the skin as a result of contact with a dog's tooth or teeth. Where there is reason to believe that a dog has bitten a person or domestic animal, where the bite is the first bite on record with the City, Animal Services shall serve the dog owner with a Notice of Caution. Where the bite is severe, the dog owner shall be served with a Notice to Muzzle. Where the bite is second or subsequent bite on record with the city, Animal Services shall serve the dog owner with a Notice to Muzzle.

As part of the investigation, Animal Services will require a witness statement from the person bitten and/or the owner of the animal that was bitten, as well as medical documentation to confirm the bite.

The purpose of the by-law is:

1. To address dogs in our community, that may present a risk to public health and safety and;

2. To ensure the owner of a dog has exercised reasonable precautions to prevent the dog from biting a person or domestic animal.

Note: restricted pit bull type dogs as defined by the Dog Owners' Liability Act, are required to be muzzled.

Removing a muzzle orderA dog owner served with a Notice of Caution or Notice to Muzzle, may request a hearing in writing within 30 days of receiving the notice. A hearing by the Executive Director may confirm the notice or exempt the owner from the muzzling requirements.
