A coroner says it's impossible to determine whether the dog that killed Christiane Vadnais in Pointe aux Trembles in June of 2016 was indeed a pit bull.
The 55-year-old woman's death sparked a movement toward establishing a controversial ban on pit bull-type dogs in Montreal.
In his report on Vadnais' death, Dr. Ethan Lichtblau wrote that such a ban on dangerous dogs isn't an effective way to deal with dog bites.
He says the dog that killed Vadnais was mistreated, frustrated and aggressive, and was often left along for long periods.
He adds his muzzle wasn't attached properly, and that there was a hole in the fence separating her backyard from her neighbor's.
Despite DNA tests, the dog was never formally identified as a pit bull.
The coroner recommends Quebec instead create a dog bite registry, and launch an awarness campaign for dog owners.
The SPCA says the report backs its argument that a ban would be ineffective and result in the death of a large number of dogs in shelters throughout the province.
