OTTAWA — The Supreme Court of Canada will not hear a bid to quash Ontario's ban on pit bulls.

The attempt to take the fight to Canada's highest court was launched in April by lawyer Clayton Ruby.

In his submission to the Supreme Court, Ruby argued there is no scientific or statistical basis to conclude that pit bulls are more dangerous than other dogs.

He asked the Supreme Court to review a decision from Ontario's Appeal Court last October that upholds the province's ban.

Today, the high court dismissed the application to hear the appeal.

The Ontario Appeal Court concluded that pit bulls are dangerous and unpredictable dogs that have the potential to attack without warning.

The Ontario government enacted the Dog Owners' Liability Act in 2005 to ban the breeding, sale and ownership of pit bulls after several incidents in which the dogs attacked people.
