Editor's note
In Table 7.5.8.4., the Column 3 heading is filed in O. Reg. 350/06 as the two-word 'Water Occupied Area'; this map reproduces the source as filed. The e-Laws consolidation drops the space between the words, rendering it as 'Water OccupiedArea'. This change was not enacted by an amending regulation.
