Tucked into the north coast of B.C. is the deepest natural harbour in North America and the port with the shortest travel times to Asia.

With growing capacity for exports including agricultural products, lumber, plastic pellets, propane and butane, it’s no wonder the Port of Prince Rupert often comes up as a potential new global gateway for oil from Alberta, said CEO Shaun Stevenson. 

Thanks to its location and natural advantages, the port can efficiently move a wide range of commodities, he said.

That could include oil, if not for the federal tanker ban in northern B.C.’s coastal waters.

“Notwithstanding the moratorium that was put in place, when you look at the attributes of the Port of Prince Rupert, there’s arguably no safer place in Canada to do it,” Stevenson said. 

“I think that speaks to the need to build trust and confidence that it can be done safely, with protection of environmental risks. You can’t talk about the economic opportunity before you address safety and environmental protection.”

Safe Transit at Prince Rupert

About a 16-hour drive from Vancouver, the Port of Prince Rupert’s terminals are one to two sailing days closer to Asia than other West Coast ports.

The entrance to the inner harbour is wider than the length of three Canadian football fields. 

The water is 35 metres deep — about the height of a 10-storey building — compared to 22 metres at Los Angeles and 16 metres at Seattle. 

Shipmasters spend two hours navigating into the port with local pilot guides, compared to four hours at Vancouver and eight at Seattle. 

“We’ve got wide open, very simple shipping lanes. It’s not moving through complex navigational channels into the site,” Stevenson said. 

A Port on the Rise

The Prince Rupert Port Authority says it has entered a new era of expansion, strengthening Canada’s economic security.

The port estimates it anchors about $60 billion of Canada’s annual global trade today. Even without adding oil exports, Stevenson said that figure could grow to $100 billion.

“We need better access to the huge and growing Asian market,” said Heather Exner-Pirot, director of energy, natural resources and environment at the Macdonald-Laurier Institute. 

“Prince Rupert seems purpose-built for that.”

Roughly $3 billion in new infrastructure is already taking shape, including the $750 million rail-to-container CANXPORT transloading complex for bulk commodities like specialty agricultural products, lumber and plastic pellets.

Canadian Propane Goes Global

A centrepiece of new development is the $1.35-billion Ridley Energy Export Facility — the port’s third propane terminal since 2019.

“Prince Rupert is already emerging as a globally significant gateway for propane exports to Asia,” Exner-Pirot said. 

Thanks to shipments from Prince Rupert, Canadian propane – primarily from Alberta – has gone global, no longer confined to U.S. markets.

More than 45 per cent of Canada’s propane exports now reach destinations outside the United States, according to the Canada Energy Regulator. 

“Twenty-five per cent of Japan’s propane imports come through Prince Rupert, and just shy of 15 per cent of Korea’s imports. It’s created a lift on every barrel produced in Western Canada,” Stevenson said.

“When we look at natural gas liquids, propane and butane, we think there’s an opportunity for Canada via Prince Rupert becoming the trading benchmark for the Asia-Pacific region.” 

That would give Canadian production an enduring competitive advantage when serving key markets in Asia, he said. 

Deep Connection to Alberta

The Port of Prince Rupert has been a key export hub for Alberta commodities for more than four decades.

Through the Alberta Heritage Savings Trust Fund, the province invested $134 million — roughly half the total cost — to build the Prince Rupert Grain Terminal, which opened in 1985.

The largest grain terminal on the West Coast, it primarily handles wheat, barley, and canola from the prairies.

Today, the connection to Alberta remains strong. 

In 2022, $3.8 billion worth of Alberta exports — mainly propane, agricultural products and wood pulp — were shipped through the Port of Prince Rupert, according to the province’s Ministry of Transportation and Economic Corridors.

In 2024, Alberta awarded a $250,000 grant to the Prince Rupert Port Authority to lead discussions on expanding transportation links with the province’s Industrial Heartland region near Edmonton.

Handling Some of the World’s Biggest Vessels

The Port of Prince Rupert could safely handle oil tankers, including Very Large Crude Carriers (VLCCs), Stevenson said. 

“We would have the capacity both in water depth and access and egress to the port that could handle Aframax, Suezmax and even VLCCs,” he said.

“We don’t have terminal capacity to handle oil at this point, but there’s certainly terminal capacities within the port complex that could be either expanded or diversified in their capability.”

Market Access Lessons From TMX

Like propane, Canada’s oil exports have gained traction in Asia, thanks to the expanded Trans Mountain pipeline and the Westridge Marine Terminal near Vancouver — about 1,600 kilometres south of Prince Rupert, where there is no oil tanker ban.

The Trans Mountain expansion project included the largest expansion of ocean oil spill response in Canadian history, doubling capacity of the West Coast Marine Response Corporation.

The Canada Energy Regulator (CER) reports that Canadian oil exports to Asia more than tripled after the expanded pipeline and terminal went into service in May 2024. 

As a result, the price for Canadian oil has gone up. 

The gap between Western Canadian Select (WCS) and West Texas Intermediate (WTI) has narrowed to about $12 per barrel this year, compared to $19 per barrel in 2023, according to GLJ Petroleum Consultants. 

Each additional dollar earned per barrel adds about $280 million in annual government royalties and tax revenues, according to economist Peter Tertzakian. 

The Road Ahead

There are likely several potential sites for a new West Coast oil terminal, Stevenson said.

“A pipeline is going to find its way to tidewater based upon the safest and most efficient route,” he said. 

“The terminal part is relatively straightforward, whether it’s in Prince Rupert or somewhere else.”

Under Canada’s Marine Act, the Port of Prince Rupert’s mandate is to enable trade, Stevenson said. 

“If Canada’s trade objectives include moving oil off the West Coast, we’re here to enable it, presuming that the project has a mandate,” he said. 

“If we see the basis of a project like this, we would ensure that it’s done to the best possible standard.”
