Our Company

Exceptional Leadership, Performance, And Execution

Leadership is what sets Lorneville apart. As one of Canada’s Best Managed Companies, our leadership team and management ensure that safety, quality, and productivity are the hallmarks of each project. We have a proven track record of success in some of the largest construction, maintenance and turnaround projects ever conducted in Northeast North America.

Lorneville is an employee-owned company. Because of this, our senior leadership team is hands-on, regularly working on job sites to verify targets are being met and that clients are well informed about the construction status. Project managers work on-site alongside engineers—adding a layer of accountability to all projects—and are expected to answer questions and solve problems immediately.

Lorneville is a large company maintaining a smaller organization’s entrepreneurial spirit and passion. Today, Lorneville is expanding its scope of operations, eyeing major projects throughout North America and around the world.
