Suppliers and building products companies serving the construction industry across Alberta — from structural materials to finishing products. If you build or supply the built environment, we want to talk.
Companies supporting Alberta’s industrial backbone — from pipeline services to logistics and energy. Operators with real crews, real contracts, and a proven track record.
Any size — from a $500k shop to a $50M operation. Owner-operated, profitable or near-profitable, and an owner ready to pass the torch. This is our family legacy, not a fund.
After acquisition, we invest in equipment, people, and processes. We help companies punch above their weight class.

William Theriault left Québec over a decade ago with a simple conviction: build something his family would be proud of for generations. Alberta’s building and construction industry was full of exceptional operators — hard-working people who had built real companies with their own hands — but with no clear path forward when it came time to step away.
Theriault Build & Holding exists to give those businesses a permanent home. Whether your company does $500k or $50M in revenue — if you built it right, we want to talk. We keep the people, honour the culture, carry the name forward, and invest for the long term. This is family legacy, not a financial transaction.
William Theriault leaves Québec and relocates to Alberta — drawn by the scale of the province’s construction industry and the opportunity to build something lasting from the ground up.
Founds his first construction company in Alberta. Spends five years building it from scratch — learning every aspect of the trade, managing crews, and delivering projects across the province.
Steps into a General Manager role in construction — leading operations, teams, and strategy at a larger scale for two years, sharpening his understanding of what makes a great company run.
Founder and sole owner of Theriault Build & Holding — actively acquiring building products and construction businesses across Alberta. Not a fund, not a flip. A family legacy built to last generations, operated with hands-on pride and a long-term commitment to Alberta’s economy.
