CALGARY, August 25, 2026, 03:18 MDT — Trading in U.S. premarket saw movement, while Canadian cash equity markets remained shut.
- Searches in Canada for “keystone xl pipeline” increased following the failure of U.S.-Canada trade negotiations.
- The Prairie Connector is the investible project, rather than the initial Keystone XL proposal with a capacity of 830,000 barrels per day.
- Prairie Connector plans a capacity of 550,000 barrels per day, of which 450,000 are backed by 20-year firm contracts.
- South Bow dropped 1.09% on August 24, indicating that investors continue to factor in execution risk.
Interest in Keystone XL searches has resurged amid rising trade tensions between the United States and Canada. However, the project presented to investors is reduced in scale, features a modified route, and remains subject to conditions.
The Prairie Connector is designed to transport 550,000 barrels of Canadian crude each day, amounting to 66% of the capacity planned for the original Keystone XL. This figure is also close to the 585,000 barrels projected to be shipped by the current Keystone system in 2025.
The difference is significant. South Bow Corporation NYSE:SOBO together with privately held Bridger Pipeline are advancing plans for the existing route. The plan involves repurposing Canadian infrastructure and running through Montana to link up with Wyoming, in contrast to a full rebuild of the previously scrapped line.
| Pipeline measure | Capacity or flow | Status |
|---|---|---|
| Original Keystone XL | 830,000 bpd | U.S. approval withdrawn in 2021 |
| Existing Keystone, 2025 average | 585,000 bpd | In operation |
| Prairie Connector proposal | 550,000 bpd | In development; decision expected by mid-2027 |
| Prairie Connector firm service | 450,000 bpd | 20-year binding agreements |
The business proposition is ahead of the political messaging. South Bow obtained binding agreements for 20 years following the completion of its open season. Firm contracts account for roughly 82% of the planned capacity.
The United States granted a presidential permit on April 30 for a 36-inch border crossing in Montana. Additional approvals are still needed at the federal, state, and local levels. The permit remains subject to amendment or revocation.
The most recent increase in searches comes after an abrupt policy shift. Canada halted trade talks after turning down updated U.S. proposals. Prime Minister Mark Carney stated Washington “asked too much and offered too little.” Canada intends to impose matching tariffs in response to 50% U.S. duties affecting about C$28 billion in goods.

The division suggests investors ought to increase the discount for cross-border permits. While long-term contracts lessen volume risk, they fail to eliminate uncertainties from route approvals, financing, construction cost inflation, or the possibility of future policy changes.
| Listed exposure | August 24 move | Investor read-through |
|---|---|---|
| South Bow NYSE:SOBO | -1.09% | Holds Canadian Keystone assets directly |
| Enbridge NYSE:ENB | -0.75% | Operates a rival export pipeline system |
| Canadian Natural NYSE:CNQ | -1.40% | Major producer of heavy oil |
| Suncor NYSE:SU | -1.53% | Exposure to integrated oil sands |
| Cenovus NYSE:CVE | -2.31% | Produces and refines heavy crude |
Shares failed to reflect a new pipeline breakthrough during Monday’s session. South Bow ended at $37.31 in New York, slipping 1.09%. Canadian Natural Resources NYSE:CNQ, Suncor Energy NYSE:SU, Cenovus Energy NYSE:CVE and Enbridge NYSE:ENB also declined.
Oil prices also declined. West Texas Intermediate closed at $85.01 on August 24, slipping 2.35%. Brent dropped to $92.17. The wider trend masks any pipeline-focused indicator in energy stocks.
Keystone pipeline throughput averaged 585,000 barrels per day in 2025, according to Canada’s regulator. The figure was down from a record 624,000 barrels a day in 2024 after pressure restrictions were implemented following an April spill. Meanwhile, expanded Trans Mountain capacity has eased transport constraints for western Canadian crude.
| Policy scenario | Pipeline consequence | Market channel |
|---|---|---|
| Trade tensions ease | Greater certainty in permitting | Reduced project risk premium |
| Tariffs remain in place | Weaker cross-border coordination | Increased discount rate and risk of delaying |
| Canada redirects exports to western markets | Prairie Connector competes with export routes to tidewater | Decreased urgency for capacity to the U.S. |
The takeaway for investors is clear. Online searches still focus on the former Keystone XL project. However, the market should price Prairie Connector instead: a more modest pipeline, largely secured by contracts and seen as commercially viable, yet facing risks from worsening relations between the two countries.
Risks: The project’s scope, expenditures and schedule are subject to change ahead of the final investment decision. Permits could be challenged in court or revoked. A slowdown in oil production growth may lessen demand for additional capacity.
The next key milestone for South Bow is a planned decision by mid-2027. Until that point, contracts underpin the outlook. The discount is set by political factors.
