FOR SALE — 2003 Peterbilt 378 • CAT C15 6NZ • Oilfield Ready
Fort St. John, BC • Serious Buyers Only
The BC/AB energy patch is heating up fast. NG Canada Phase 1 is live, Phase 2 is approved in Kitimat, and Coastal GasLink post-construction is moving full swing with reclamation and new compressor/meter stations. Cedar LNG enters major construction through 2026. Montney operators (Paramount, ARC, Strathcona) are tying in new pads, pushing infrastructure, and locking in 2026 drilling programs.
Pipeline integrity digs, winter replacements, Enbridge/TMX upgrades, Red Chris mine expansion, and northern road/port upgrades are already driving demand.
Winter roads are open. Crews are moving. Equipment is moving daily.
If you need iron that works now, this is it.
