Canada is the world's fourth-largest oil producer and largest exporter to the United States. Western Canadian Select (WCS) heavy crude trades at a discount to WTI reflecting transportation constraints and quality differentials. The Trans Mountain Expansion pipeline opened export capacity to the Pacific Coast in 2024.
Current Context
WCS-WTI differentials have narrowed since Trans Mountain came online, but remain elevated during U.S. refinery turnaround season. Canadian oil sands production continues to grow modestly despite policy headwinds. Spring breakup typically reduces rig counts seasonally.
