Together, we thrive!

Mainstay Engineering & Owner Reps is a professional engineering company that has distinguished itself by successfully overseeing mining projects valued at over $1B dollars.

We are committed to shared excellence and community prosperity. Our majority owner — Buffalo River Development LP, a wholly-owned entity of Buffalo River Dene Nation (BRDN) — anchors these values and provides strategic direction.

Together, BRDN and Mainstay are playing an important role in Saskatchewan’s thriving mining and industrial sector. We are fostering meaningful opportunities for Indigenous communities through strategic partnerships, workforce development, education, business development, and community relations.

Vision: Together, we will create meaningful opportunities and a brighter future for tomorrow’s Indigenous leaders and working professionals.

Mission: We make it easier for Canadian mining and industrial companies to find qualified construction management professionals and engineering services for their teams.
