• (b) The owner of a vacant Part IV or Part V Heritage Property shall protect the building and property against the risk of fire, storm, neglect, intentional damage or other damage by other causes by effectively preventing the entrance of the elements, unauthorized persons or the infestation of pests by boarding up and securing any openings to the building in the following manner:

• (iv) all boards used for boarding and securing openings not located in a window or door opening shall be painted or otherwise treated so that the colour blends with the exterior of the building or structure.
