Trans-Northern Pipelines Inc

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.  We have been operating pipelines for more than 60 years and are committed to operating in a safe and environmentally responsible manner in order to protect the public, the environment and the pipeline.  TNPI is also committed to working with landowners, regulators and others in the communities where we operate because we all play a role in pipeline safety.

Our History
