Currently, two active development sites in/near Trefann Court: 187 Parliament and 252 Parliament. Other previously approved developments are apparently waiting for the market to improve. The diagram below shows heights of a number of existing/planned towers in the north part of Queen-River area.
Building heights as shown may have been approved by the city or the OLT, but in the future, the developers may ask for further height increases. For example, 307 Sherbourne (SE corner of Gerrard) got OLT approval in 2019 for a 15-storey building with 112 residential rental units. Now the developer wants permission for an 18-storey, student residence containing 223 units on that site.
The distinctive Watt Group office (300 Bayview), designed by architect Barton Myers in 1984, was visible from the Queen St bridge over the Don Valley; the Watt building was demolished last year, to provide parking for the Audi dealership (328 Bayview).
