Canada’s pipeline expansion plans outpace oil sands production growth and capital investment, analysts warn
Canada has ambitious plans to expand its crude export infrastructure, with six pipeline projects in various stages of planning or development — from incremental expansions to Enbridge’s Mainline and the Trans Mountain system to a proposed 1-million-barrel-per-day east-west corridor to the Pacific coast. But analysts warn the country’s oil sands producers may not be growing fast enough to fill the pipes being planned. Capital investment and production growth are both lagging well behind what the proposed capacity would require.
Pipeline ambitions exceed current production trajectory
Canada’s existing crude export pipeline capacity is already running close to full. Roughly 90% of Canadian oil flows south to the United States, which makes new pipeline capacity a logical ambition — but filling it is where the math gets complicated. Enbridge executive vice-president Colin Gruending acknowledged the gap plainly on a recent conference call: “Producers are behaving with discipline. I think they’ll get there. We were just a little too quick off the line here.”
The six projects under consideration span a wide range of scale and risk. Incremental expansions to the Enbridge Mainline and Trans Mountain system could move forward relatively quickly and cheaply. The proposed 1-million-bpd east-west corridor to the Pacific coast is a different proposition entirely — larger, costlier, and far more uncertain. About 950,000 bpd of the total proposed incremental capacity would ship oil to the U.S., including a proposal that would revive portions of the former Keystone XL route.
Even under optimistic scenarios that include projects still in planning stages, projected supply falls well short of what the proposed infrastructure would require.
Capital investment in oil sands has fallen sharply since 2014
The production shortfall doesn’t exist in isolation. It reflects a decade of declining capital spending in Canada’s oil sands sector. Annual investment peaked at C$35 billion in 2014, according to Statistics Canada, then dropped to C$14.2 billion by 2024 — less than half the peak level.
Imperial Oil CEO John Whelan put it plainly at a conference in June: over the past decade, the oil sands industry spent roughly C$10 billion per year less than it did in the decade before. The last major new oil sands project — Suncor’s Fort Hills mine — began operating in 2018. Since then, companies have concentrated on expanding existing facilities rather than breaking ground on new ones.
The scale of investment required to change that trajectory is significant. Whelan estimated that filling the proposed east-west pipeline alone — along with building the carbon capture infrastructure the Canadian government says must accompany it — would require more than C$100 billion in new capital. Not impossible, but it would demand a fundamental shift in how oil sands companies currently approach spending decisions.
Production growth is slowing and projected supply falls short of pipeline demand
Canadian oil production hit a record 5.35 million barrels per day in 2025, a 4% increase over the prior year, with most analysts projecting another 3% to 4% growth in 2026. Solid numbers in absolute terms — but they pale against the 8%-plus annual growth rates that defined the 2000s and 2010s, when large new oil sands mines were actively under construction.
Energy consultancy Novi Labs identified 19 oil sands growth projects — proposed by companies including Cenovus Energy, Imperial Oil, Strathcona Resources, and Suncor — that could collectively add 652,000 bpd of production by 2037. Only some of those have received final investment decisions.
When Novi Labs expanded its analysis to include longer-term projects that companies have flagged in medium- and long-term plans but haven’t committed to yet, the projected supply picture improved — but still fell short of what the proposed pipelines would require by more than 850,000 bpd. Wood Mackenzie analyst Mark Oberstoetter noted the contrast with earlier eras: “It’s stuff the oil sands has done in the past. But then you had a different view on long-term oil prices, arguably, and kind of a growth-at-all-means mantra at some of these companies which seems quite different today.”
Policy uncertainty and geopolitical factors shape the investment outlook
The investment climate isn’t entirely discouraging. Canadian oil executives say they feel more optimistic than they have in years, pointing to Prime Minister Mark Carney’s pledges to accelerate project permitting and roll back or soften a range of environmental and climate regulations. The goal is partly economic — boosting oil exports as a buffer against tariff pressure from the United States. Short-term international demand for Canadian crude has also picked up as the Iran war disrupts global oil trade flows.
Optimism and policy commitments aren’t the same thing, though. Many of the changes negotiated between the industry and federal and Alberta governments — including frameworks around carbon pricing, financial supports, and permitting timelines — haven’t yet been written into final legislation. Kendall Dilling, president of the Oil Sands Alliance, captured the conditional nature of the moment: “Will we see some big projects moving ahead if we get these investment conditions right? That’s absolutely our objective.”
Long-term demand uncertainty, tied to both domestic climate policy and global energy transition trends, continues to weigh on producer confidence. It doesn’t make investment impossible — but it does make the case for large, multi-decade commitments considerably harder to close.
What this means for Canada’s pipeline future
The core takeaway is straightforward: Canada’s pipeline ambitions are real, but they’re running ahead of the production and investment trends needed to support them. Existing capacity is nearly maxed out, oil sands capital spending sits at less than half what it was a decade ago, and production growth has slowed considerably from its earlier pace. Even under optimistic scenarios that include projects still in planning stages, projected supply falls well short of what the proposed infrastructure would require. Policy changes could shift the calculus, but they haven’t been finalized. Until investment picks up and production growth accelerates, the gap between pipeline plans and pipeline reality is likely to stay wide.
