Since the start of September 2025, the price discount applied to Canada’s heavy crude oil exports from the West Coast terminal of Westridge, British Columbia (BC), the terminus of the expanded Trans Mountain Pipeline (TMX), has been narrower than for heavy crude oil re-exported via U.S. Gulf Coast terminals. This marks the second time this year that heavy oil barrels off the West Coast have been fetching stronger relative prices.
As discussed in RBN’s TradeView Report, when considering the price discount applied to the heavy crude oil export stream designated as Pacific Dilbit Blend (PDB) that is exported from Westridge, its price discount (blue line in chart below) to the NYMEX-CME WTI Calendar Month Average (CMA) has been narrower than $(2)/bbl since the beginning of September and similar to levels where it traded between March and May 2025.
