Read the business cases for Bowmanville Extension
Lakeshore East Line GO Expansion
Before a construction project can begin, Metrolinx undertakes various studies to help make decisions about the project. These studies include a business case, which presents evidence and analysis to explain why a project should be built, and an environmental assessment, which identifies potential impacts of a project and proposes ways to avoid, reduce or minimize them.
The following studies and reports were undertaken to support major work required to implement the GO Expansion program on the Lakeshore East Line.

Find out what we mean when we talk about some of our reports, studies and processes.
A business case is a report that is written to explain why a project should be built. It includes the benefits that a project would deliver, as well as potential risks. Metrolinx creates business cases for major projects to secure approval before moving on to detailed project studies, such as the Transit Project Assessment Process. Business cases provide evidence to decision-makers, stakeholders, and the public as a crucial part of transparent and evidence-based decision making processes.
Improvements are underway along the Lakeshore West Line to support more frequent, faster service.
We're transforming GO Transit to bring more frequent two-way, all-day service to the Barrie Line.
