Built to Take On the Toughest
Whissell Contracting Ltd.
Established in 1970, Whissell Contracting has grown into one of Western Canada’s most trusted civil infrastructure partners. With over 325+ pieces of equipment and dedicated teams in Calgary, Lethbridge, and Leduc, we deliver large-scale underground utilities, earthworks, industrial, and transportation services across Alberta. We’re known for taking on the projects that others walk away from: deep utilities, high-risk corridors, complex diversions, and environmentally sensitive sites. Around the industry, they call them “Whissell projects.”
Our advantage is simple: experienced people, proactive planning, modern equipment, and a culture where safety and quality are non-negotiable.
The work no one sees, but everyone depends on. Whissell is the expert in underground construction with extensive experience ranging from subdivision servicing to infrastructure projects and everything in between. Deep utilities, trunk mains, lift stations, diversions, and complex tie-ins. Precision at depth. Performance under pressure.
Underground Infrastructure
From raw ground to ready-for-build. Mass excavation, site development, pad construction, ponds, slopes, and large-scale grading powered by one of Alberta’s most capable fleets.
Earthworks & Grading
When it needs to move, we move it. From oversized loads to specialized equipment and materials, Whissell’s experienced drivers and dispatch team deliver heavy haul solutions that keep projects on schedule. No route too complex. No load too demanding. Just disciplined logistics and dependable delivery, every time.

Built responsibly. Delivered confidently. From landfill construction and remediation to slope protection, wet works, and complex industrial civil projects, Whissell delivers with precision, discipline, and environmental care.

Don't Just Take Our Word For It.
"I’m fortunate to work alongside strong coworkers and have great mentors out of Calgary who I can rely on for guidance and support when needed. That kind of environment makes a big difference day-to-day. In addition, the stability and compensation provide a solid foundation that allows me to stay focused and committed. I feel like I can come to work each day with a clear sense of purpose, contribute meaningfully to the team, and continue developing my skills."
“The variety of work at Whissell is what keeps me motivated. No two days are the same, and I’m constantly learning from different teams and challenges. It’s rewarding to be part of a company where I can grow my experience while contributing to meaningful solutions. What really stands out is the support from the team—there’s a strong sense of collaboration, and people genuinely want to see you succeed.”
"The culture from the top to the bottom the team Whissell has created is what keeps me coming back. Why should someone want to work at Whissell? Because of their commitment to respect people and to keep them safe and healthy.”
