About the study

Halton Region has undertaken a Municipal Class Environmental Assessment (MCEA) Study for the Norval West Bypass from Highway 7 to 10 Side Road (Regional Road 10), including 10 Side Road from Tenth Line to Adamson Street/Winston Churchill Boulevard (Regional Road 19), in the Town of Halton Hills.

Process and consultation

The study was carried out in accordance with Schedule C of the Municipal Class Environmental Assessment (MCEA), (October 2000, as amended 2007, 2011, 2015, 2023 and 2024), which is an approved process under the Ontario Environmental Assessment Act. A key component of the MCEA Process is consultation with the public, review agencies, Indigenous Communities, First Nations and Métis Communities, and other interested parties. Two Public Information Centres were held throughout the study to obtain input on the project. The Environmental Study Report (ESR) has been prepared to document the planning, public consultation, and decision-making process undertaken for this study.
