Colony Construction delivers steel construction services in the Yukon for mining, hydroelectric, and remote industrial clients. We have been building in the territory for decades, including structural steel for the Mayo B hydroelectric expansion, and our fabrication, logistics, and cold-weather execution capabilities are matched to the realities of Arctic and subarctic construction.

Colony Construction in the Yukon

The Yukon is a demanding construction environment. Winter temperatures regularly reach -40 C, sites are often accessible only by long-haul truck or winter road, and the summer building season is short and intense. Colony’s four decades of northern construction experience – across the Yukon, Northwest Territories, Nunavut, and northern BC – built the capabilities owners expect in this territory: Arctic-grade steel specifications, cold-weather welding procedures, and logistics discipline that treats the narrow access window as sacred.

Colony Construction Yukon

Colony’s completed Yukon work includes structural steel for the Mayo B hydroelectric expansion, a Yukon Energy project on the Mayo River that added generating capacity critical to the territory’s power supply. Beyond Mayo B, our northern mining portfolio across Brucejack, Red Chris, Diavik, Kupol, and Antamina directly informs how we approach Yukon gold, silver, and polymetallic projects in the Dawson Range, the Finlayson district, and the emerging Rackla belt.

Every Yukon project is engineered to the National Building Code as adopted by the territory, with snow, wind, and seismic loads from NBC climatic data and CVN-qualified steel matched to the site’s temperature range. Whitehorse, Dawson City, Mayo, Faro, and remote exploration and mining camps are all within reach of our logistics network.

Industries We Serve in the Yukon

The Yukon’s construction demand is concentrated in mining and energy, with a smaller base of remote infrastructure and industrial support work.

Featured Projects in the Yukon

Mayo B Powerhouse

Mayo B Powerhouse

Colony fabricated and erected structural steel for Yukon Energy’s Mayo B hydroelectric expansion on the Mayo River, adding generating capacity to a site in operation for more than 50 years. The project required cold-weather erection, remote logistics, and close coordination with Yukon Energy and its engineering partners to deliver the powerhouse steel into a compressed northern construction season.

Why Choose Colony Construction in the Yukon?

  • Mayo B delivered: Completed structural steel for a major Yukon Energy hydroelectric project – proven northern execution, proven Yukon client references.
  • Arctic construction DNA: Cold-weather steel, winter welding procedures, and erection practices proven across the Yukon, NWT, Nunavut, and northern BC.
  • Remote logistics: Experience with long-haul truck, winter road, and staged Whitehorse-area transshipment for remote mining and exploration sites.
  • Short-season discipline: Fabrication sequenced to hit the narrow Yukon construction window, with pre-assembly and pre-coating where appropriate to compress field time.
  • Single-source delivery: Engineering, detailing, fabrication, and design-build under one contract – ideal where logistics and schedule risk are the dominant constraints.

Frequently Asked Questions – Construction in the Yukon

Has Colony Construction built in the Yukon before?

Yes. Colony fabricated and erected structural steel for the Mayo B hydroelectric expansion, among other Yukon projects, and brings experience from parallel work across the NWT, northern BC, and international remote sites.

How does Colony handle Yukon cold-weather steel?

Steel is specified with Charpy V-notch toughness matched to the site’s temperature range, welding procedures are qualified for cold-weather service, and erection crews work with heated enclosures and winter work practices where needed.

Can Colony ship steel to remote Yukon mining camps?

Yes. Whitehorse-based staging, long-haul truck, and seasonal-access logistics are standard parts of our Yukon work. We plan fabrication and shipping around the territory’s narrow access windows.

What codes does Colony design to for Yukon projects?

The National Building Code as adopted by the Yukon, with CSA S16 for structural steel and CSA W59 for welding. Snow, wind, and seismic loads are pulled from NBC climatic data for the specific site.

Can Colony support Yukon Energy hydro projects?

Yes. Colony’s Mayo B experience with Yukon Energy is directly applicable to future hydro, transmission, and generation-support projects across the territory.
