Mainstay Engineers is pleased to announce the acquisition of RCH Consulting Ltd., a Saskatchewan-based engineering consultancy with a strong reputation for practical solutions, technical expertise, and trusted client relationships. 

The addition of RCH strengthens Mainstay's engineering capabilities and expands the depth of experience we bring to clients across Canada's mining and industrial sectors. 

The two organizations share a common approach to engineering: understand the client, solve the right problem, and deliver practical solutions that work in the real world. 

This acquisition marks another important step in Mainstay's growth. As a Saskatchewan-based, Indigenous-owned engineering company, we are continuing to build the expertise, capacity, and local presence needed to support clients through every stage of project delivery. 

We are proud to welcome the RCH team to Mainstay and excited about what we'll build together.
