The Ontario Line will transform transit in Toronto, getting hundreds of thousands of people where they need to be—better, faster and easier than today. However, we know that a project of this size and complexity means we need to help communities plan for and adjust to some changes both during and after construction.

Public input is vital to the project and we thank you for your patience as we complete the necessary studies and investigations to support more detailed plans which will be shared with the public as they are available.

We are doing our part to protect our staff and the public during the COVID-19 virus. During this time, our engagement has moved to a virtual format.

Our team is continuing to support our residents, business and communities. Please contact us with any questions.
