1946
The Beginning
Chester and Florence Brown began making concrete drain tile in their barn while waiting for their orchard to grow—unknowingly laying the foundation for what would become Coldstream Concrete. Their hands-on approach and work ethic set the tone for a business rooted in quality and determination.
1960's
Stepping Into Production
As demand grew, the Browns purchased their first tile machine, shifting from small-batch handmade production to a more efficient and scalable process. It marked the start of Coldstream’s evolution into a true manufacturing operation.
1970's
Rapid Growth
The need for concrete drain tile skyrocketed, and Coldstream kept pace with three machines running and ten kilns in operation. Some days saw 30 to 40 truckloads heading out—evidence of both the industry’s momentum and the company’s rising reputation.
1980's + 1990's
Industry Leadership
In 1980, Bob Brown was President of the Land Improvement Contractors of Ontario (LICO), strengthening Coldstream’s influence in the industry. During this time, the company continued to build on its reputation for reliability, quality, and leadership in precast innovation.
2000's
Heavy Precast Milestone
Coldstream completed and installed its first heavy precast culvert on Petty Street—a major milestone that marked their entry into custom heavy precast work and showcased their
growing capabilities in infrastructure-grade solutions.
2010's
Industry Leadership
The company continued to grow its offerings and, in 2013, expanded into reinforced concrete pipe by purchasing new forms. This move completed their product line for the site servicing industry and positioned them to serve larger and more complex projects.
2020's
A New Chapter with Deep Roots
The 2020s have been a time of growth and transition for Coldstream Concrete. In 2023, Amy Koteles—third generation—became the sole owner, continuing the legacy built by her family with a renewed focus on innovation and expanding their custom precast capabilities.
In December 2024, the company lost a respected leader and mentor, Bob Brown. His dedication, integrity, and influence shaped the business for decades, and his legacy continues to guide the team forward.
