Trans-Northern Pipelines Inc. (TNPI) operates regulated pipelines in central Alberta from Edmonton to Calgary, and in the south eastern Ontario to Montreal corridor, delivering refined petroleum products such as gasoline, diesel fuel, aviation fuel and heating fuel used by businesses and consumers.

TNPI was incorporated in 1949, and has been operating pipelines for more than 60 years. Our business is built on four strategic pillars which we work to uphold every day: Personal and Process Safety, Environmental Sustainability, Reliability and People. Our team’s decades of experience combined with a focus on our core values – safe, respectful, professional, trustworthy, results focused, decisive – guides our daily activities and business operations.

We are also committed to building relationships with people, municipal officials and other personnel in the communities where we operate so that they know us and we can work together to ensure pipeline safety. Our pipeline is clearly marked with marker signs that show the public that there is a TNPI pipeline nearby and how to contact us.
