McIntosh Perry’s depth of knowledge and decades of experience enable us to expertly design and rehabilitate any transportation infrastructure asset. Public and private clients throughout North America trust us to deliver innovative solutions that address the unique construction challenges bridges, culverts, and other transportation structure projects pose.

These complex initiatives require the involvement of multiple parties with whom we have developed close working relationships. This allows us to move projects forward with the support of local governments and municipalities, transportation authorities, conservation agencies, telecom and power companies, railways, Indigenous Communities, suppliers, contractors and more.

Guided by a philosophy of sustainability that is built into our engineering service offerings, we make highly informed decisions that help clients reach their goals while considering critical social, environmental, and economic impacts. We’re also keenly aware that effective communication is integral to achieving project success. 

Thus, we work diligently to be a supremely responsive partner that is easy to work with and openly shares information. As a result, we have formed long-lasting relationships with clients such as the Ministry of Transportation Ontario (MTO), the City of Ottawa, the City of Toronto, and Alberta Transportation.

Our structural engineers, transportation planners, contract and construction administrators, and other personnel maintain top-tier certifications and belong to many professional organizations, including the Professional Engineers Ontario (PEO) and the Canadian Society of Civil Engineering (CSCE). We are honoured to have won numerous awards for excellence in engineering at events like the Association of Consulting Engineering Companies (ACEC)-Ontario Engineering Project Awards and to consistently present our work at global conferences such as the International Conference on Short and Medium Span Bridges.
