You’re invited to attend a virtual open house on January 25 from 6:30-8:30 p.m. about zoning by-law amendments needed to facilitate the delivery of the Ontario Line and Scarborough Subway Extension.

The City of Toronto in collaboration with Metrolinx and the Province of Ontario are working to deliver numerous transit expansion projects.

During the design, review and approval of each project, the City checks zoning compliance. If a project does not comply with current zoning, the City undertakes an amendment to the City’s zoning by-law 569-2013 or other prevailing bylaws.

Please continue to check this web page for updates.

Why the Zoning By-law is Being Amended

The City is undertaking zoning by-law amendments for these transit projects because these projects require relief from the City’s standards. For example, a transit project needs to locate an emergency exit building on a property and will create a new lot for it. But the zoning by-law would require a much bigger size for the new lot due to minimum required setbacks by-law. So the City changes the by-law by reducing the setbacks so that the emergency exit lot can be as small as possible. This way there is less land taken away from the original property.

Some common zoning issues for transit projects include: setbacks, gross floor area, lot coverage and sometimes use.

Most lands throughout the City can be used for public transit but in some cases where the existing zoning does not allow public transit as a use, the City is changing the by-law to allow the land to be used for public transit.


The City started its zoning review for the Scarborough Subway Extension and the Ontario Line in fall 2021. The draft amendments are now being reviewed by City Legal, Toronto Building and Zoning staff, as well as other stakeholders such as Metrolinx.

The City will host an open house and public information centre on January 25, 2022 from 6:30-8:30 p.m.


Following this, staff will make recommendations and bring a report to Council in March and April 2022.
