Coastal Gaslink workers are in Houston working with members of the First Nations to gain knowledge about the local area.
Shawn Howard, spokesperson for TransCanada, said the project is about sharing culturally important knowledge between generations.
"The program creates the opportunity for one generation to pass down to another the traditional and cultural knowledge specific to areas along our proposed pipeline route," Howard said.
"This knowledge is built up by First Nations through generations of living in close contact with nature. Examples include favourite hunting, fishing and trapping locales, traditionally used trails and travel ways."
The program concluded last week and Howard says the study will inform Coastal GasLink for their project planning and detailed engineering design.
"We appreciate the support of the participating Hereditary Chiefs in carrying out this program on their lands, with their people… We have been working with all of the hereditary and band leadership along the proposed pipeline route and people have been notified of our work before we enter a particular area. We will continue to do so," Howard said.
