Years Assessing Waste Disposal Systems
Our Partners
“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”
“We are very thankful for all that Gerry and his company have done for us up to now…their expertise and assistance has facilitated the process of purchasing a good quality septic system that meets the Ministry of Environment’s standards.”
“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!”
