2018 Greater Sudbury Lateral Replacement
Union Gas has replaced portions of the Greater Sudbury Lateral Pipeline System to ensure the continued reliable delivery of natural gas and serve an increased demand in Greater Sudbury and surrounding area.
The project involved removing an existing 10-inch diameter pipeline and replacing it with approximately 19 kilometres of new 12-inch pipeline.
The project occurred in two sections: the first between the existing Union Gas Coniston and Frood Road Stations, and the second between the Union Gas Azilda and Walden Stations. (Please click on the map image to the right to see the project route).
OEB review and approval was required before this project could proceed. Union Gas submitted a Leave-to-Construction application to the OEB on May 5, 2017. On Sept. 28, 2017, the OEB approved the project. Work began in April 2018 and the project went in-service in late October. Clean-up work will continue into 2019.
A key part of the planning process involved consultation with local landowners, Indigenous communities, government agencies, project neighbours, and other stakeholders that could be impacted by the project. Union Gas engaged interested parties through project notices and letters, individual meetings/phone calls (where requested), regular website updates, and through pre-construction information sessions.

Environment a priority
Union Gas is committed to minimizing the effects of our projects and operations on the environment.
AECOM was retained by Union Gas to prepare an Environmental Report to assess any potential environmental and socio-economic effects that may result from the project and outline plans for avoiding and/or mitigating any effects, where possible. Examples of potential environmental considerations that will be assessed in the report include, but are not limited to:
- Existing land uses, local residents and businesses
- Designated natural areas, woodlots, wetlands and other vegetation (e.g. hedgerows)
- Wildlife and wildlife habitats
- Watercourses and waterbodies, aquatic species and habitats
- Species at Risk
- Groundwater resources
- Soils, bedrock geology and extractive resources (aggregates)
- Archaeological resources and built heritage
The Environmental Report was prepared in accordance with the OEB's Environmental Guidelines for the Location, Construction and Operation of Hydrocarbon Pipelines and Facilities in Ontario (2016). The report accompanied the Leave-to-Construction application that was submitted to the OEB. Please view the main Environmental Report here, and check out the appendix as well. (Note: The appendix file contains numerous high-resolution graphics and may take several minutes to load.)
The local community will benefit from the incremental taxes that Union Gas will pay annually.
