Credit River Valley Project

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

Credit River Valley Project

Project facts

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

Timing: Work began in the spring of 2019 and was completed in late summer 2019.


Drilling technique: Imperial installed the pipeline segment beneath the Credit River using a horizontal directional drill (HDD), the most advanced and least intrusive technique available to install underground pipeline.

Permitting and community engagement: Before any work commenced, Imperial secured all required permits and completed a thorough assessment of the project’s effects on the environment.

Work area

Imperial followed all City of Mississauga, provincial and national bylaws and safety standards – and worked with neighbours to minimize the impact of traffic and noise from construction. Imperial also worked to ensure 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.

Protecting the local environment


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

Safe decommissioning: As part of the replacement process, once the new line was successfully installed, Imperial safely decommissioned the existing pipeline. Trained workers cleaned and injected the segment with cement/grout to ensure the ground surface would not sink or settle.

Our commitment to community engagement and transparency

Community and stakeholder input helps inform our solutions. We engaged in dialogue with community members, Indigenous groups, government and other stakeholders regarding our company’s practices and construction projects. This included a neighbourhood information session in the spring of 2018, direct engagement and ongoing updates through this project webpage.
