For several years now, TORONTO has been remaking its downtown social housing.  The revitalization of REGENT PARK  is well underway, and DON MOUNT COURT (renamed RIVERTOWNE) is a fait accompli.  Located east of the Don River south of Dundas Street East, the neighbourhood mixes private and public housing in a complex of rowhouses and a four-storey apartment building.  In the middle – a large park and playground; around the perimeter, the many shops and attractions of Queen Street East.  As in REGENT PARK, the street grid has been re-opened as well.
