Highway 69 Four-Laning from north of Harris Lake Road to north of Magnetawan River (Project 3)

The Minister of the Environment has designated this project and the environmental assessment will continue under the former Canadian Environmental Assessment Act.

The Ontario Ministry of Transportation (MTO) is undertaking a 102 km capacity expansion initiative along Highway 69 from north of Highway 559 to Murdock River. The 102 km initiative as proposed by MTO consists of five separate project phases, each of which is undergoing a separate federal environmental assessment screening. Collectively, the five federal screenings are assessing the entire 102 km initiative. The screening referred to under this Notice of Commencement relates to Project 3 of the Highway 69 initiative, which includes capacity expansion works from north of Harris Lake Road to north of Magnetawan River (approximately 7 km). This undertaking will primarily involve re-alignment and widening (four new lanes on a new alignment) of the existing highway. The scope of project includes all aspects of the development proposal related to the construction, operation and modification of Highway 69 from north of Harris lake Road to north of Magnetawan River. This will include four-laning of Highway 69 on a new alignment, construction of a new interchange, and construction of a new water crossing. For additional information relating to the screenings of projects 1, 2, 4 and 5 of the Highway 69 initiative, please refer to CEAR numbers 11-01-65457, 11-01-65415, 11-01-65418 and 06-01-22108, respectively. MTO is anticipating that the phases will be constructed in the following sequence: Project 5, Project 4, Project 1, Project 2, Project 3. Since planning for each phase is advancing independently, there may be changes to the construction sequence in the future.
