It looks like WAM development has plans for this stretch of Queen St east. According to a recent BisNow article: In Toronto, WAM has two downtown sites staked for development. On the south side of Queen east of Sherbourne, it’s assembled nearly 10 parcels, including a car dealership, to form a four-acre site. Stefan says the vision (above) is for three residential towers (1,730 units) and 300k SF of commercial space, with retail-lined laneways providing passage from Queen to Richmond Street (below). “We’re place-making on Queen,” notes Rob, who lived on the block for years. “With the sheer size of this, and the pedestrian connectivity, and rejuvenation of Queen, we’ll be creating a neighbourhood hub, which it’s lacked for so long.” I didn't find an application on the City's website... I recall reading a while ago that these might be purpose built rental.
