The only information I have regarding the Overlea blvd location is that they wanted to include a gas station, but that idea was shot down.
As a result, Costco may be rejecting the plan.
What surprises me is that they go ahead with a Costco Business in a former Zellers store but they did not choose to put one in the former target space in the Thorncliff mall...at least temporarily until they get things worked out across the street.
(assuming that the two level Target there has the same or similar square footage as the one level Zellers on Thermos road... ???)
