I'm not all that educated on how developments like these go through the system. Where's it at right now? Did it deal with that initial site refusal?
Currently they are clearing the conditions of approval set by the Ontario Land Tribunal (OLT) at their settlement in March. Most of these conditions are technical in nature (eg. revisions to landscape or servicing). Once this is done, the city's zoning by-law will be officially amended to allow this development.
However if the proponent actually wants to build this they will need to get Site Plan Approval (SPA) which is a separate application that they have not submitted yet. Building permits would be the step after that.
