Credit River Valley Project

This ~575m segment replacement is a preventative measure to mitigate changing river flow and its impact on the line. The size of pipe as well as volume and type of product it carries will not change.

Project facts

Location: Credit River Valley just north of Highway 403 and east of Mississauga Road.

Timing: Work is anticipated to begin in the fall of 2018; completion in the spring of 2019.

Drilling technique: Imperial will install the 12-inch nominal pipeline segment beneath the Credit River using a horizontal directional drill (HDD), which is the most advanced and least intrusive technique available to install underground pipeline.

Permitting and community engagement: Before any work commences, Imperial will have all required permits and will complete a thorough assessment of this project’s effects on the environment. Imperial is also committed to meaningful community and stakeholder engagement for this project.

Supplying Mississauga and the GTA: The pipeline is critical infrastructure supplying refined fuel products to people, businesses and community organizations in the Mississauga and the Greater Toronto Area, including a significant portion of product used at Toronto Pearson International Airport.

Work period*

*Timeline is subject to permit approvals.

Work area

Imperial will follow all City of Mississauga, provincial and national bylaws and safety standards – and will work with neighbours to minimize the impact of traffic and noise from construction.

  • Southwest side and staging area:  Access to both the staging area and construction road will come off Mississauga Road
  • Northeast side: Access to the construction road will come off the Wellsborough Place cul-de-sac, at the site of Culham Trail
  • Work area: All work will take place in the lands owned and administered by Infrastructure Ontario and Hydro One

Protecting the local environment

Imperial is committed to the highest standards of water and environmental protection during the installation work – and for the ongoing safe operation of the pipeline.

Water protection: Imperial has developed contingency plans in case of flooding, or other scenarios, to mitigate any risks to the work area and surrounding environment.

Safe decommissioning: The segment replacement will require decommissioning the current pipeline, which will cause the least disturbance to the local environment. As part of the decommissioning process, trained workers will clean and inject the segment with cement/grout to ensure the ground surface will not sink or settle.

Horizontal directional drill

We know the Credit River is important to the community and that is why we are using the most advanced and least intrusive technique for installing underground pipeline: horizontal directional drill (HDD).

HDD is a trenchless method of installing underground pipe using a drilling rig at the surface level with minimal impact on the surrounding environment.

  • Proposed HDD entry side is located west of the Credit River
  • Stage 1 - Drill a small diameter pilot hole along a designed directional path
  • Stage 2 - Enlarge the pilot hole to a diameter suitable for installation of the pipeline
  • Stage 3 – Pull the pipeline back into the enlarged hole
  • Proposed exit side is east of the Credit River where there is sufficient space for the work

Our commitment to community engagement and transparency

Community and stakeholder input helps inform our solutions. We are look forward to a dialogue with community members, Indigenous communities, government and other stakeholders regarding our company’s practices and construction projects, such as this pipeline segment replacement.

We are committed to sharing what we know and responding to your questions. This includes a neighbourhood information session in the spring of 2018, direct engagement and ongoing updates through this project webpage.
