I'm not sure if this has been posted anywhere yet, but there is a proposal to re-zone the sites at 2 Leikin, 20 Leikin, and 99 Bill Leathem to allow a warehouse and truck terminal as uses.
Looks like someone is proposing to construct a warehouse here. The land has been vacant for a long time. The area has good access to Fallowfield which leads to the 416 relatively quickly, and Prince of Wales to go south to Bankfield for potential access to the 416 there.
