Our History
1991–1995
TULLOCH is founded in 1991 in Thessalon, Ontario, through the purchase of a modest surveying practice. The company expands into civil engineering and completes early First Nations survey projects, building a strong foundation in geomatics and municipal services. All seven founding employees stay with TULLOCH throughout their careers, setting an early example of loyalty and commitment.

1996–2005
TULLOCH secures its first major contract administration project following MTO privatization, establishing a long-term presence in transportation. The company expands through acquisitions in Huntsville and Sault Ste. Marie, enters the energy sector through work on early Ontario wind farms, and begins the tradition of company-paid tropical vacations for staff and families.

2006–2012
TULLOCH grows through strategic acquisitions in environmental services, surveying, geotechnical engineering, structural engineering, and materials testing. New offices in Sudbury and Ottawa strengthen the firm’s provincial presence, while the Sault Ste. Marie team increases its technical capacity. The Ottawa expansion adds geospatial and LiDAR pioneers behind the world’s first highway LiDAR survey.

2013–2018
TULLOCH expands across Northern Ontario with new offices in Parry Sound, Espanola, Elliot Lake, Thunder Bay, and Timmins, supporting growth in the mining sector. The company also strengthens its Southern Ontario presence through the acquisition of A. J. Clarke & Associates, expanding land development capabilities and earning recognition as Northern Ontario Business of the Year.

2019–2021
TULLOCH cements its national footprint with offices in Calgary and Toronto, strengthening its service offerings through strategic acquisitions in surveying and engineering. The company introduces an employee ownership program, broadens its capabilities in the buildings and industrial sectors, and builds a more connected technical team to support clients across Canada.

2022–2026
TULLOCH becomes a nationally recognized firm, earning Canada’s Best Managed Companies and Great Place to Work certifications, additional local workplace honours, and industry project awards. The company grows its integrated land development expertise, expands into the United States with offices in Pennsylvania and Michigan, surpasses major safety milestones, and modernizes operations and facilities across locations.
