Concept 2 Keys (C2K) is improving the development review process and the experience for both City staff and development applicants. This includes improving processes, fostering consistency, resolving application issues early and introducing digital resources. These improvements build on recommendations from the End-to-End Review of the Development Review Process.

The systemic improvements being implemented by C2K continue to be tested and refined through expedited reviews of affordable housing projects and are now being implemented on a wider scale in the Etobicoke York District.

Learn more about Concept 2 Keys and how it’s improving the City’s development review process.

The City’s new online Application Submission Tool (AST) is available for use by all development applicants in Toronto.

The AST was tested and refined by applicants in the Etobicoke York District and those with affordable housing applications that are part of Concept 2 Keys. An easy and secure way for them to upload new applications and supporting materials, the AST also gives applicants the ability to check the status of applications in real time.

At this time, the tool only supports the initial submission of development review applications. All resubmissions will still be handled in the same manner as they are today.

You can now add up to five people from your team who are associated with the file submission. By doing so, they will also receive email notifications updating them on the progress of the application submission and informing them of status changes. You will no longer be required to forward the email updates, if you have had to do so in the past.

This feature can be found on the ‘Add People’ screen.

A new file circulation tool coming in 2022 will enable City staff and commenting partners to review planning applications, provide comments and revise planning drawings in a coordinated and collaborative manner.

Newly formed application review teams made up of City staff from commenting divisions are working on applications for affordable housing and in the Etobicoke York District. Working as a team, they ensure applicants are provided with clear and consistent information and guidance.

Application coordinators are fostering collaboration and issues resolution among the City’s new application review teams. They are also working closely with affordable housing applicants to meet expedited timelines related to various forms of funding.

Mandatory pre-application consultation is a formal meeting between a development applicant, City staff and relevant external commenting partners, held at the beginning of the development review process.

Pre-application consultation is currently voluntary in Toronto, but most applicants participate in some form of pre-application consultation with City staff prior to submitting a development application. Making pre-application consultation mandatory provides an opportunity to improve and formalize an already well-used practice and support timely review of a development application.

Improvements to the early stages of the development review process, beginning with mandatory pre-application consultation, result in the submission of higher-quality applications, increase the number of applications moving from pre-application consultation to actual submission, reduce the overall number of circulations and help to establish mutual accountability between applicants and staff early on.
