Throughout the province, there is a growing pride in our heritage. Communities boast of their commercial buildings, courthouses, places of worship, gardens, natural heritage and other heritage sites. From April through October, communities open the doors of some of our most intriguing and charming heritage sites. Admission is free. And the Ontario Heritage Trust – the province's lead heritage agency – invites you to experience these hidden heritage treasures first-hand.
