November 2021 Update

As part of next steps, in the near future, the Town plans to seek additional input from the community to help finalize its preferred Highway 7/12 Alternative Route in north Whitby. As part of this fourth round of community engagement, the public, businesses owners and interested parties will soon be encouraged to review and discuss Alternative F versus the current Technically Preferred Alternative B-R. Get a preview of the two routes to be further discussed in this map. Notifications will be sent to interested and impacted parties in advance of the community engagement opening.

The additional community engagement is coming soon further to Council approving the following resolution earlier this month:

“That Staff and the Environment Assessment (EA) Study Team be directed to review the Thickson Road option based on the planned future 4/5 lane Regional design terminating at the intersection of Highway 7/12 south of Brawley Road against the weighting of the preferred option, and following consultation with the Region of Durham, MTO, and MECP and a review of defensibility, report to Council with respect to next steps and the financial impact of pursuing the Mid-Block and Thickson Road as an alternative for the Highway 7/12 route as part of the enhanced consultation”.

We look forward to sharing more details in the near future.

About the Highway 7/12 Alternative Route Environment Assessment Study

As the population grows in Whitby and the Greater Toronto Area, usage of Highway 7 and 12 is increasing. To support the traffic infrastructure needs of the community and accommodate this future growth, the Town has initiated a Provincial Class Environmental Assessment (EA) Study to determine an alternative route(s) for provincial traffic that does not go through the Downtown Brooklin area.

The study will evaluate alternative options for the route and recommend a preferred plan to address both the local and provincial traffic needs of the study area.

The Study Design Report was finalized after the first Connect Whitby round of community engagement conducted in June 2020. The report describes the study background, approach, process, alternatives and public consultation program.



Information will be collected in accordance with the Municipal Freedom of Information and Privacy Protection Act. With the exception of personal information, all comments will become part of the public record.
