The Miller Group is pleased to announce the acquisition of the assets of Summit Aggregates KW Inc. from founders Bill and Betty Kester.
Markham, ON, March 20, 2026 – The Miller Group is pleased to announce the acquisition of the assets of Summit Aggregates KW Inc. from founders Bill and Betty Kester. We are grateful for their trust in us to carry on their legacy.
Established in June 2013, Summit Aggregates has built a strong reputation for exceptional customer service and high-quality material supply—values that align closely with Miller’s own longstanding philosophy. Strategically located within our Tri-City Materials market, Summit’s operations play an important role in supporting both regional growth and customer demand.
Summit Aggregates operates from a well-positioned pit in Ayr, Ontario, complete with an onsite wash plant. Overall, the acquisition provides Miller with access to over 25 million tonnes of reserves and strengthens our ability to service both internal and external customers with a wide range of aggregate products for concrete, hot mix and infrastructure construction.
Like Miller, a significant strength of Summit is its dedicated employees, and we are pleased to welcome them to our Miller Family, our Team. Summit Aggregates will continue to operate under its existing name as we integrate our operations and work together to enhance service to the market.
This acquisition marks an important milestone as we continue expanding our materials network. It clearly reinforces our ongoing commitment to quality, outstanding service, and strategic growth, all of which are supported by both Miller and Colas Canada.
The Miller Group is a Colas company in Canada, a Canadian leader in the construction and maintenance of transportation infrastructure. Founded in 1917, The Miller Group builds and supports urban and rural infrastructure across Canada. Additional information can be found on The Miller Group’s website.
