The licensing and standards committee will debate a report next week that calls for big changes to animal bylaws in the city.
It suggest that the owners of dogs who have bitten people or other pets place a warning sign on their property.
It also proposes that the “dangerous dogs” wear a tag to be sold by the city revealing its past.
The report will include a clear definition of what a “dangerous dog” is.
The definition being put forward is a dog that has severely bitten a person or a domestic animal one time.
The new rules would also include dogs that have attacked a person or an animal more than once, regardless of the severity.
There are roughly 230,000 dogs that live in Toronto.
The report will be debated September 21 and then be open to feedback from the public.
