“I would be happy to recommend Canadian Shield Consultants Agency and I would hire them again if the need arose.”

Madeleine Nadon, Homeowner

“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!”

Wayne Johnson, Manager - YMCA-YWCA of Winnipeg

“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”

Jean McConnell, Former Manager of Recreational Arenas and Swimming Pools - City of Greater Sudbury

“Throughout the entire month long project CSCA did not veer from the original goal and made MRWs time in St. Charles a positive experience.”
