  • Sodexo Canada has been a partner with TNDC since 2002, providing complete camp management through Spatsizi Remote Services. During this time we have worked on many projects, and employed many Tahltan members. It’s been very positive, and the business relationships have formed long lasting personal and business friendships.

  • TNDC is a great place to work. The atmosphere in the office is friendly, open, and honest, and there is always humour and laughter. I like that TNDC maintains an active approach of hiring locally and offers training within that position. Employees are highly encouraged and supported to advance professionally, which ripples into advancing personally as well.

  • We formed our Tahltan Aeronigma Geodis Wilson partnership in 2011. It’s been an honour to partner with TNDC for the opportunity to provide our wide-range of global logistical services and be a part of a world class organization built on mutual cooperation, trust and respect.

  • We worked with TNDC on the Galore Creek mining project and the Northwest Transmission Line, providing heavy lift helicopter services. It made good business sense to get involved with the Nation, so we formed Tahltan Helifor Joint Venture in 2011. After meeting Bill Adsit, I knew we had made the right decision. We have had only positive experiences and look forward to continued collaboration.
