Analysis-Canada's pipeline ambitions hinge on uncertain output expansion

Canadian pipeline companies are proposing billions in new projects, but expansion is hampered by production uncertainty. Six pipeline projects are underway or proposed to increase export capacity by 45% by 2035. However, Canadian oil output would need to increase by over a third by 2034, nearly doubling its current growth rate. Major new oil sands projects, which haven't been undertaken in over a decade, would also be required.

Suncor Energy and Canadian Natural Resources have not yet committed to accelerating production increases. Enbridge, a pipeline operator, postponed plans for a second phase of its Mainline expansion due to lack of customer commitment. Canadian oil is the world's fourth-largest producer, with 90% shipped to the US. While global buyers are interested due to Iran's war disrupting oil trade, long-term demand growth is uncertain due to climate policies and geopolitics.

Only some proposed projects have received final investment decisions, falling short of filling proposed pipelines by over 850,000 barrels per day.
