“ 22. The urban agglomeration council may, by a by-law that is subject to the right of objection under section 115, identify the thoroughfares forming the arterial road system in the urban agglomeration.
It does so by listing the names and numbers of the thoroughfares or by identifying them on a map, plan or other illustration.
When such thoroughfares are identified in the order made under section 135, the urban agglomeration council may amend or repeal that identification in the manner provided for in the first paragraph. If it only amends the identification of the thoroughfares and the thoroughfares are identified only on a map, plan or other illustration, the by-law must state how the new identification differs from the former. ”.
