signed with the Greater Sudbury Housing

Corporation, you have agreed that you would not

construct or install a fence ( or other structure)

without written permission of the Greater Sudbury

Housing Corporation. 

 As explained in Article 23: Alterations,

“The tenant shall not  make any alterations to the rental

unit or alter the equipment or install fixtures in the rental

Fences or other structures that are installed without written permission are a violation of the terms of your lease, and you will be required to remove them at your own expense.
