Build Toronto has submitted a District Plan for the Allen District, which is located within the Downsview Area Secondary Plan area. The Allen District is generally located south of Sheppard Avenue West, on either side of Allen Road.

The Downsview Area Secondary Plan requires the completion of a District Plan to the satisfaction of the City prior to any development proceeding in a District. The purpose of the District Plan is to set out a finer grain level of detail for the development of the area. The District Plan is where streets and blocks are laid out with detailed information on land use, built form, massing and treatment of the public realm. It is also where a Public Art Strategy, Community Services and Facilities Strategy and Affordable Housing Strategy are refined to reflect a cohesive framework from which to draw from as development occurs. The District Plan is also important in setting out a Phasing Plan for the growth of the District.

Pursuant to the Downsview Area Secondary Plan, District Plans are required to be completed to the satisfaction of the City prior to any development proceeding.
