Overview
- Trans Mountain will hold an open season this year to contract capacity unlocked by drag‑reducing chemicals now in testing.
- The program targets roughly 70,000–75,000 barrels per day of additional throughput by late 2026 or early 2027.
- Existing egress from Alberta is on track to be full around 2027 as currently configured, prompting operators to prioritize incremental upgrades over a new pipeline.
- The expanded line averaged about 730,000 barrels per day in the first half of 2025, with volumes projected near 90% of its 890,000‑barrel capacity in the second half.
- No proponent has advanced a second West Coast line, as Ottawa signals private‑sector leadership, Alberta promotes a Prince Rupert route, and Enbridge says policy certainty is a prerequisite.
