The City of Toronto Design Review Panel was approved by City Council as a pilot project in June 2006 and made permanent in November 2009. The Panel is an important voice for the promotion of design excellence within Toronto, and plays a significant leadership role for design professions within the development approvals process.
The Design Review Panel assists Council in fulfilling Official Plan objectives by providing City staff with professional design advice on public and private development. The Panel's goal is to improve people's quality of life by promoting design excellence within the public realm, including the pursuit of high quality architecture, landscape architecture, urban design and environmental sustainability. The Panel also plays a significant role in engendering an informed, public debate about the importance of good design within our City.

Though they could be doing a much better job. Providing they don't restrict designs so much that you end up with slight variations of the same design as seen in other cities.
