There seems to be little going on at the retaining wall site these days. It may have to do with negotiations ongoing with the owner at the north end of the wall. If the owner withholds permission for the wall to be completed on the end property, plans will need to be adjusted.
Incidentally, the storm sewer pipe that is visible in the second image is one of hundreds that flow into the Humber. The structure above it may serve to prevent slope erosion.
