Engineers - Consulting. The measure of a professional consulting firm is best taken by a demonstrated ability to provide its stated services, by the volume of its repeat business, and especially by the calibre of its people. We believe Upper Canada Consultants offers a service and quality advantage that few consultants in our chosen fields can match. More than 80 percent of our growing business comes from clients with whom we have previously worked. As an organization, Upper Canada Consultants offers a breadth of in-depth experience on projects that range across the spectrum of complexity and engineering expertise.
