The explanation "stream not present" is clearly misleading for this changeset, in which an attempt was made to delete several features that are clearly visible from aerial imagery, for example this building https://www.openstreetmap.org/way/733569388 or the trails underneath the HydroOne power line. If the building(s) have been demolished, the changeset comment should say so. I am reverting these edits now for being unsubstantiated.
