Good eye (the background hills are wrong for the location) and it seems the source (Wasaga Beach Chronicle) seems a little dodgy and appears to be simply and aggregator of social media and bloggers. However, in spite of no official announcement, CTV has reported on it, the major has disclosed they have been approached by "a large retailer" for the site and the local Simcoe.com news site has published an apparently site plan diagram submitted by the property owner. It seems like a very poorly kept secret.
