Celebrating over 20 years. Beaver Valley Stone was established in 1989 by Tony Pacitto who had been in the landscape supply/home beautification business for many years already. It started out with a few acres of land and has slowly built up to over 15 acres with many different varieties of natural stone and precast concrete products to choose from. Beaver Valley Stone has one of Canada's largest outdoor displays for you to walk through and in-vision a backyard oasis for yourself.
