About Us

Moncrief Construction Limited (MCL) is a general contractor specializing in power and communications line construction, industrial electrical work, heavy civil construction, and aggregate production.

Founded in 1967 by Harold and Margaret Moncrief, MCL has grown from a small hydro- and telephone-line company to become one of Northwestern Ontario’s largest and most diversified construction companies.

Based out of Kenora, Ontario and operating primarily in Northwestern Ontario and Manitoba, MCL has completed projects across Canada. Our civil division builds roads, bridges, causeways, lagoons, pipelines, and dams. Our electrical and powerlines divisions construct substations and remote transmission lines, and light the communities and airports of the North. Our aggregate division drills, blasts, and crushes Canadian Shield rock for the roads and industry of the region. Our transportation, mechanical, and administrative personnel provide support to our crews and equipment. MCL’s satellite construction yards and properties throughout the region provide ideal staging grounds for our wide range of projects.

Since our beginnings, MCL has grown to employ close to 100 year-round personnel, with up to 200 additional seasonal workers and over 200 pieces of equipment. We are proud to be part of a number of partnerships and joint ventures with First Nations communities in the region, and to be members of numerous prequalification, safety, and construction associations.

MCL’s continuing commitment to integrity, dependability, and quality workmanship have allowed us to build strong relationships with major contractors, with provincial and municipal government departments and First Nations, and with private clients in the energy, mining, and communications sectors. From small private residential projects to multi-million dollar contracts, there are few jobs too large or small for MCL. Our corporate resume proves that we have the experience, capabilities, and resources to tackle any challenge.
