Q&A with Gary Mar, CEO of the Canada West Foundation

Building a stronger Canadian economy depends as much on how we move goods as on what we produce.

Gary Mar, CEO of the Canada West Foundation, says economic corridors — the networks that connect producers, ports and markets — are central to the nation-building projects Canada hopes to realize.

He spoke with CEC about how these corridors work and what needs to change to make more of them a reality.

CEC: What is an economic corridor, and how does it function?

Gary Mar: An economic corridor is a major artery connecting economic actors within a larger system.

Consider the road, rail and pipeline infrastructure connecting B.C. to the rest of Western Canada. This infrastructure is an important economic corridor facilitating the movement of goods, services and people within the country, but it’s also part of the economic corridor connecting western producers and Asian markets.

Economic corridors primarily consist of physical infrastructure and often combine different modes of transportation and facilities to assist the movement of many kinds of goods.

They also include social infrastructure such as policies that facilitate the easy movement of goods like trade agreements and standardized truck weights.

The fundamental purpose of an economic corridor is to make it easier to transport goods. Ultimately, if you can’t move it, you can’t sell it. And if you can’t sell it, you can’t grow your economy.

CEC: Which resources make the strongest case for transport through economic corridors, and why?

Gary Mar: Economic corridors usually move many different types of goods.

Bulk commodities are particularly dependent on economic corridors because of the large volumes that need to be transported.

Some of Canada’s most valuable commodities include oil and gas, agricultural commodities such as wheat and canola, and minerals such as potash.

CEC: How are the benefits of an economic corridor measured? 

Gary Mar: The benefits of economic corridors are often measured via trade flows.

For example, the upcoming Roberts Bank Terminal 2 in the Port of Vancouver will increase container trade capacity on Canada’s west coast by more than 30 per cent, enabling the trade of $100 billion in goods annually, primarily to Asian markets.

Corridors can also help make Canadian goods more competitive, increasing profits and market share across numerous industries. Corridors can also decrease the costs of imported goods for Canadian consumers.

For example, after the completion of the Trans Mountain Expansion in May 2024 the price differential between Western Canada Select and West Texas Intermediate narrowed by about US$8 per barrel in part due to increased competition for Canadian oil.

This boosted total industry profits by about 10 per cent, and increased corporate tax revenues to provincial and federal governments by about $3 billion in the pipeline’s first year of operation.

CEC: Where are the most successful examples of these around the world?

Gary Mar: That depends how you define success. The economic corridors transporting the highest value of goods are those used by global superpowers, such as the NAFTA highway that facilitates trade across Canada, the United States and Mexico.

The Suez and Panama canals are two of the most significant trade infrastructure projects ever built, facilitating 12 per cent and five per cent of global trade, respectively. Their success is based on their unique geography.

Canada’s Asia-Pacific Gateway, a coordinated system of ports, rail lines, roads, and border crossings, primarily in B.C., was a highly successful initiative that contributed to a 48 per cent increase in merchandise trade with Asia from $44 million in 2006 to $65 million in 2015.

China’s Belt and Road initiative to develop trade infrastructure in other countries is already transforming global trade. But the project is as much about extending Chinese influence as it is about delivering economic returns.

CEC: What would need to change in Canada in terms of legislation or regulation to make more economic corridors a reality?

Gary Mar: A major regulatory component of economic corridors is eliminating trade barriers.

The federal Free Trade and Labour Mobility in Canada Act is a good start, but more needs to be done at the provincial level to facilitate more internal trade.

Other barriers require coordinated regulatory action, such as harmonizing weight restrictions and road bans to streamline trucking.

By taking a systems-level perspective – convening a national forum where Canadian governments consistently engage on supply chains and trade corridors – we can identify bottlenecks and friction points in our existing transportation networks, and which investments would deliver the greatest return on investment.

“The refining industry wants heavy oil. We are actually in a shortage of heavy oil globally right now, and you can see that in the prices”

Once priced at a steep discount to its lighter, sweeter counterparts, Canadian oil has earned growing admiration—and market share—among new customers in Asia.

Canada’s oil exports are primarily “heavy” oil from the Alberta oil sands, compared to oil from more conventional “light” plays like the Permian Basin in the U.S.

One way to think of it is that heavy oil is thick and does not flow easily, while light oil is thin and flows freely, like fudge compared to apple juice.

“The refining industry wants heavy oil. We are actually in a shortage of heavy oil globally right now, and you can see that in the prices,” said Susan Bell, senior vice-president of downstream research with Rystad Energy.

A narrowing price gap

Alberta’s heavy oil producers generally receive a lower price than light oil producers, partly a result of different crude quality but mainly because of the cost of transportation, according to S&P Global.

The “differential” between Western Canadian Select (WCS) and West Texas Intermediate (WTI) blew out to nearly US$50 per barrel in 2018 because of pipeline bottlenecks, forcing Alberta to step in and cut production.

So far this year, the differential has narrowed to as little as US$10 per barrel, averaging around US$12, according to GLJ Petroleum Consultants.

“The differential between WCS and WTI is the narrowest I’ve seen in three decades working in the industry,” Bell said.

Trans Mountain Expansion opens the door to Asia

The price boost is thanks to the Trans Mountain expansion, which opened a new gateway to Asia in May 2024 by nearly tripling the pipeline’s capacity.

This helps fill the supply void left by other major regions that export heavy oil – Venezuela and Mexico – where production is declining or unsteady.

Canadian oil exports outside the United States reached a record 525,000 barrels per day in July 2025, the latest month of data available from the Canada Energy Regulator.

China leads Asian buyers since the expansion went into service, along with Japan, Brunei and Singapore, Bloomberg reports. 

Asian refineries see opportunity in heavy oil

“What we are seeing now is a lot of refineries in the Asian market have been exposed long enough to WCS and now are comfortable with taking on regular shipments,” Bell said.

Kevin Birn, chief analyst for Canadian oil markets at S&P Global, said rising demand for heavier crude in Asia comes from refineries expanding capacity to process it and capture more value from lower-cost feedstocks.

“They’ve invested in capital improvements on the front end to convert heavier oils into more valuable refined products,” said Birn, who also heads S&P’s Center of Emissions Excellence.

Refiners in the U.S. Gulf Coast and Midwest made similar investments over the past 40 years to capitalize on supply from Latin America and the oil sands, he said.

While oil sands output has grown, supplies from Latin America have declined.

Mexico’s state oil company, Pemex, reports it produced roughly 1.6 million barrels per day in the second quarter of 2025, a steep drop from 2.3 million in 2015 and 2.6 million in 2010.

Meanwhile, Venezuela’s oil production, which was nearly 2.9 million barrels per day in 2010, was just 965,000 barrels per day this September, according to OPEC.

The case for more Canadian pipelines

“The growth in heavy demand, and decline of other sources of heavy supply has contributed to a tighter market for heavy oil and narrower spreads,” Birn said.

Even the International Energy Agency, known for its bearish projections of future oil demand, sees rising global use of extra-heavy oil through 2050.

The chief impediments to Canada building new pipelines to meet the demand are political rather than market-based, said both Bell and Birn.

“There is absolutely a business case for a second pipeline to tidewater,” Bell said.

“The challenge is other hurdles limiting the growth in the industry, including legislation such as the tanker ban or the oil and gas emissions cap.”

A strategic choice for Canada

Because Alberta’s oil sands will continue a steady, reliable and low-cost supply of heavy oil into the future, Birn said policymakers and Canadians have options.

“Canada needs to ask itself whether to continue to expand pipeline capacity south to the United States or to access global markets itself, which would bring more competition for its products.”
