Northern Shield: proposed 3,300-km pipeline from Hardisty to Sarnia

What happened

• The government announced the proposed Northern Shield Energy Corridor: a 3,300-km pipeline from Hardisty, Alberta to the Sarnia refining and petrochemical hub.

By the numbers

• Initial capacity: about 500,000 barrels per day, expandable to 800,000 barrels per day.
• Projected timeline: a feasibility study (including costs, commercial models and related opportunities) is underway and expected to finish by the end of 2026.

Who it affects

• Sarnia-Lambton refineries and petrochemical plants, regional workers and manufacturers (the release highlights use of Ontario steel and local labour).
• Indigenous partners and communities (the province says it has begun duty-to-consult processes).
• Potentially Manitoba and port interests if extensions (including study of a route to the Port of Churchill) move forward.

What’s next

• Ontario will complete the feasibility study, define estimated costs and commercial models, and continue consultations. The announcement is a proposal; the pipeline and any Strategic Petroleum Reserve remain subject to study and further decisions.
