In an effort to curb puppy mills and animal cruelty, a Toronto city council committee has voted to restrict pet stores to selling dogs and cats that only come from shelters, humane societies and certified breeders.

Reputable breeders will include registered humane societies, registered shelters, municipal animal shelters and rescue groups.

The move is being seen as a compromise to many animal rights groups who were calling for an outright ban on selling dogs and cats in pet shops.

Toronto doesn’t currently certify breeders, but advocates for the change argue the cost of certification would be minimal compared to the dangers of puppy and kitten mills, where animals are often mass produced and kept in squalid conditions.

The full city council will vote on the measure on June 14.

If it passes, Toronto will become the second Canadian city to restrict the sale of animals in pet shops. Richmond, B.C. decided to ban the sale of dogs in pet stores in 2010.
