Sorry, don't know anything.
It could be that with the Costco now going to Granite Drive, that this proposed development has been put on the back burner. It should be noted that
Corey Craig also had big plans for a major retail plaza on the west side of Harrisville too, but that seems to be on the back burner now too. There is after all room for only so much retail in Moncton, and in general, bricks & mortar is having a hard time of it these days.
Plaza REIT has included a listing for "Moncton East Lands" on their inventory for property to be developed for some time. I suspect this is on the east side of Harrisville, but again, I suspect with Costco going to Granite that nothing will happen here either.

Granite Drive will be developed at the expense of Harrisville, and with some cannibalization of the Trinity/Mapleton district too,
