When TC Energy cancelled the Energy East pipeline in October 2017, it represented the death of a vision: Canadian oil flowing from Alberta to Atlantic refineries and export terminals, reducing eastern dependence on foreign crude while creating a new export route to global markets.
The $15.7 billion project would have transported 1.1 million barrels per day across 4,600 kilometers—from Alberta through Saskatchewan, Manitoba, Ontario, Quebec, and into New Brunswick. Approximately 70% of the route would have repurposed existing natural gas infrastructure, reducing new construction requirements.
TC Energy cited economics: oil prices had collapsed to under $40 per barrel, Keystone XL had received U.S. approval, and Trans Mountain Expansion was advancing. But the political reality was equally decisive. Quebec opposition—led by Montreal Mayor Denis Coderre and amplified by environmental groups—had made the project a regulatory quagmire.
Eight years later, the landscape has fundamentally changed.
The Polling Shift
A SOM-La Presse poll from February 2025 shows 59% of Quebecers now support reviving Energy East. Support has grown from 33% in 2019 to 47% nationally, with Quebec no longer the monolithic opposition bloc it once was.
The Angus Reid Institute found two-thirds of Canadians nationally support pipeline renewal. The shift reflects a fundamental recalculation of energy security priorities in the wake of U.S. tariff threats and trade uncertainty.
Why Quebec Changed
Several factors explain Quebec's evolution:
Tariff Anxiety
Donald Trump's 25% tariff threats forced Quebecers to confront their economic vulnerability. The province's manufacturing sector depends on U.S. market access. When the American president spoke of Canada as "the 51st state," abstract concerns about energy sovereignty became concrete.
Foreign Oil Dependence
Despite Canada holding the world's third-largest proven oil reserves, eastern Canadian refineries source the majority of their crude from foreign suppliers. Quebec and Ontario import more than half their oil from international sources—including shipments from less stable or adversarial regimes.
The Irving Oil refinery in Saint John—Canada's largest at 320,000+ barrels per day—processes approximately 115,000 barrels daily of imported Saudi crude. Energy East would have provided a domestic alternative.
Political Leadership Shift
Premier François Legault has moved from dismissing Alberta oil as "dirty energy" to acknowledging Quebec would consider energy proposals with "social acceptability." While not an endorsement, the rhetorical shift signals openness that didn't exist in 2017.
The Infrastructure Advantage
Energy East's most significant asset may already exist: approximately 3,000 kilometers of natural gas pipeline infrastructure in Saskatchewan, Manitoba, and Ontario that could be converted to oil service.
This infrastructure—designed to NPS 42 specifications (1,067 mm diameter)—represents sunk capital that could continue delivering value. Repurposing existing pipelines rather than building new ones reduces costs, environmental footprint, and regulatory complexity.
The remaining new construction would focus on pipeline segments through Quebec and New Brunswick, plus the marine terminal infrastructure at Saint John.
The Political Landscape
The current federal Conservative government under Prime Minister Pierre Poilievre has promised a "Canada First National Energy Corridor" to fast-track critical infrastructure approvals. Legally binding commitments from all government levels in pre-approved transport corridors would reduce the regulatory uncertainty that plagued the original Energy East.
Prairie premiers have enthusiastically endorsed revival. Alberta Premier Danielle Smith has aggressively pushed for Energy East discussions, with Saskatchewan Premier Scott Moe echoing support.
The challenge remains Quebec. While polling shows majority support, translating that support into political action requires Quebec leadership willing to champion the project—not merely tolerate it.
Indigenous Considerations
The original Energy East route crossed more than 130 Indigenous territories, affecting traditional lands of 180+ Aboriginal communities. Most communities opposed the project, citing inadequate consultation and concerns about environmental impacts.
The Ontario Energy Board found widespread dissatisfaction with the consultation process. Indigenous demands extended beyond compensation to protection of rights, cultural recognition, and meaningful decision-making power.
Any revival would face heightened scrutiny on Indigenous engagement. The federal fast-track corridor cannot, as the Globe and Mail editorial board noted, "run over First Nations." Meaningful partnership models—potentially following the equity ownership approaches demonstrated by Cedar LNG and the Enbridge Westcoast transaction—would likely be necessary.
Economic Impact
The original project economic analysis projected:
- Jobs: 321,000 one-year full-time equivalent positions over the project lifecycle
- Construction employment: 48,700 peak jobs
- Operations: 7,900 national jobs over 40 years
- GDP contribution: $25.3 billion over 40 years
- Tax revenue: $7.6-10 billion over project lifetime
These figures require updating for 2026 conditions—higher labor costs, updated commodity prices, and modern safety standards—but illustrate the project's economic scale.
The Business Case Challenge
Despite political momentum, no private company has announced plans to revive Energy East.
The corporate hesitation reflects hard experience. Canadian energy companies have spent a decade navigating regulatory delays, political opposition, and cost escalations on major projects. Trans Mountain required federal government acquisition to proceed. Northern Gateway was cancelled after years of review. Energy East itself died despite significant investment in regulatory process.
As one former pipeline executive observed: "It's going to be daunting for any corporate board in Canada to take the risk."
The economic fundamentals have also shifted. Trans Mountain Expansion now provides Pacific export capacity. Keystone XL, while cancelled by the Biden administration, demonstrated the volatility of cross-border projects. The business case for Energy East depends on:
- Sustained high oil prices justifying new infrastructure investment
- U.S. tariff restrictions making alternative export routes attractive
- Long-term offtake commitments from eastern refineries and export customers
- Regulatory certainty that previous projects lacked
Energy Sovereignty Frame
The most compelling argument for Energy East isn't commercial—it's strategic.
Canada is the only major oil-producing nation where a significant portion of its own territory imports foreign crude. Eastern Canadians heat their homes with oil that arrives by tanker from Saudi Arabia, Algeria, and Nigeria while western Canadian production flows almost entirely to U.S. markets.
This configuration made sense when North American energy integration was the dominant policy paradigm. In an era of tariff threats and trade weaponization, it creates vulnerability.
Energy East would provide redundancy: multiple export routes rather than dependence on U.S. pipeline infrastructure, domestic supply for eastern refineries rather than foreign imports, and Atlantic export capacity for global markets.
The Path Forward
Energy East revival requires several preconditions:
Private Sector Champion: A company or consortium willing to invest development capital despite regulatory history.
Quebec Political Support: Provincial leadership actively championing—not merely permitting—the project.
Indigenous Partnership: Meaningful equity participation or benefit structures for affected communities.
Federal Fast-Track: Major Projects Office designation and corridor pre-approval reducing regulatory timeline.
Market Economics: Commodity prices and trade conditions supporting the business case.
Whether these conditions align remains uncertain. What has clearly changed is the political possibility. A project that was unthinkable in Quebec five years ago now commands majority public support. Converting that support into infrastructure requires political leadership, corporate risk tolerance, and Indigenous partnership that didn't exist in 2017.
At SHIFT, we help energy companies navigate the stakeholder and political challenges of major project development. Energy East's potential revival represents one of the most complex communications environments in Canadian infrastructure—spanning provincial politics, Indigenous relations, environmental concerns, and federal policy. The companies that succeed will be those that build genuine coalitions rather than merely managing opposition.
