Dempster Fibre Line – Closing the gap in Canada’s North

The Dempster Fibre Line is one of ROHL’s most ambitious northern deployments. Spanning approximately 800 kilometers, the route parallels the Dempster Highway from Dawson City (Yukon) to Inuvik (Northwest Territories). With this line, remote regions transition from relying on a single fiber path to having a redundant, resilient connection. Once reaching Inuvik, the line links into the existing Mackenzie Valley Fibre Connection to complete a critical backbone route in Canada’s North.

CHALLENGES

Harsh environment & remote terrain: permafrost, tundra, river crossings, minimal road access

Sparse infrastructure support: limited staging areas, logistics complexity for supplies

Climatic constraints: short construction windows, extreme cold, weather delays

Network reliability needs: remote communities cannot tolerate outages

Regulatory & stakeholder complexity: multiple jurisdictions, Indigenous land consultation

SOLUTION/APPROACH

ROHL delivered a turnkey solution from vision to handover, using proven methodology refined over decades of remote builds. Key elements included:

Terrain‑specific construction techniques: specialized plows, directional drilling, trenching suited to permafrost zones

Redundant network design: ensuring alternate paths and resilience

Testing & integration: strict QA/QC, fiber verification

We coordinated with local stakeholders and regulatory bodies to maintain alignment and compliance throughout the build.

OUTCOMES

800 km of new fiber backbone

Enabled redundant connectivity to previously single-path remote regions

Strengthened network resilience and reliability in the far north

Laid critical infrastructure for future expansion and service growth

Contributed to economic, communications, and emergency service stability in remote communities
