“Throughout the entire month long project CSCA did not veer from the original goal and made MRWs time in St. Charles a positive experience.”
“In my opinion, the true test of a good business is whether or not you would use their services again. In the case of Canadian Shield Consultants Agency, Gerry and his crew, the answer is we still are using their services and we consider them our “Go To” guys!”
Based on our experience, I confidently recommend Canadian Shield for any sewage design and installation projects. Their reliability, workmanship, and client-focused approach make them an excellent partner for any organization. It was a pleasure to work with them and I look forward to continuing the relationship in a maintenance scope moving forward.
“We were very impressed with your heavy duty machinery, and realized we were not dealing with a start-up company. All workmen on the site knew their jobs and performed all labour with such care and skill. I must add a personal comment that the workers were very amicable, answered all our questions and did not mind the interruptions when we asked for clarification as to what they were doing”
