Credit River Valley Project

This roughly 600 metre segment replacement is a preventative measure to mitigate changing river flow and its impact on the line.

Project facts

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

Timing: Work began in the spring of 2019; completion is anticipated in the fall of 2019.

Drilling technique: Imperial will install the 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

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.

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.

Imperial also recognizes the importance of collaboration with local Indigenous groups when conducting activities of their traditional territories.

Project approvals and/or permits:

Horizontal directional drill (HDD)

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

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 groups, 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 included a neighbourhood information session in the spring of 2018, direct engagement and ongoing updates through this project webpage.
