As U.S. President Donald Trump’s 30-day pause on sweeping tariffs nears its end, Canada is bracing for a potential economic earthquake.
With less than three weeks left before the implementation of 25% tariffs on most Canadian exports and a 10% levy on energy, the ripple effects could devastate cities across the country.
A shocking new report from the Canadian Chamber of Commerce’s Business Data Lab (BDL) reveals which Canadian cities are most vulnerable, and the findings might leave you stunned.
From energy hubs like Calgary to auto manufacturing giants like Windsor, the economic fallout could reshape Canada’s landscape.
But it’s not just the big players at risk—workers, businesses, and consumers nationwide could feel the pinch.

The Tariff Threat: A Game-Changer for Canada-U.S. Trade
The United States has long been Canada’s largest trading partner, with billions of dollars in goods crossing the border annually.
However, Trump’s protectionist policies, including the latest round of tariffs announced in early 2025, threaten to upend this delicate balance.
The 25% tariff on most exports and the 10% energy tariff is part of a broader strategy to prioritize American industries, but for Canada, the consequences could be catastrophic.
The BDL report, released this week, uses a “U.S. Tariff Exposure Index” to rank Canada’s 41 largest cities based on their dependence on American trade.
The results paint a grim picture for some regions, with energy, auto, and steel industries bearing the brunt.
But why are these tariffs so dangerous, and how did we get here?
Experts say the tariffs respond to perceived trade imbalances, with Trump arguing that Canada has benefited unfairly from access to U.S. markets.
“These tariffs are a political move to appease American voters, but they’re a sledgehammer to Canada’s economy,” says Dr. Emily Carter, a trade economist at the University of Toronto.
“Canada’s economy is deeply integrated with the U.S., especially in key sectors like energy and manufacturing.
Disruptions here could lead to job losses, higher prices, and a domino effect on related industries.”
The 30-day pause, announced in January 2025, was meant to give both nations time to negotiate, but with talks stalling, the clock is ticking.
If the tariffs take effect, they could trigger a trade war reminiscent of the 2018 steel and aluminum tariffs, which strained bilateral relations.
This time, however, the stakes are higher, with broader sectors at risk.
The Most Vulnerable Cities
The BDL report doesn’t pull any punches, highlighting 10 Canadian cities that could face the worst fallout.
Let’s break down each one, exploring why they’re at risk and what it means for local economies.
1. Saint John, New Brunswick
At the top of the list is Saint John, a port city in New Brunswick with deep ties to the energy sector.
Home to the Irving Oil Refinery—Canada’s largest—the city ships over 80% of its refined products to the U.S.
With the new 10% tariff on Canadian oil and gas, Saint John’s economy could take a massive hit.
“We’re talking about potential price increases, production cuts, and job losses,” says local business owner Mark Thompson.
“The refinery is the backbone of our community, and if it struggles, so do we.”
The report estimates that Saint John’s exposure to U.S. tariffs is the highest in the country, with energy exports making up a significant chunk of its GDP.
For residents, this could mean higher fuel costs and fewer opportunities, especially in an already vulnerable region.
2. Calgary, Alberta
Calgary, long known as Canada’s energy capital, comes in second on the list.
The city exports a staggering $119.4 billion worth of goods to the U.S., accounting for 80.4% of its GDP.
With energy tariffs looming, the report warns of price hikes and production cuts that could ripple through Alberta’s economy.
“Calgary is built on oil and gas, and these tariffs could be a death knell for smaller producers,” says Dr. Raj Patel, an economist at the University of Calgary.
“We’re already seeing layoffs in the sector, and this could accelerate the trend.”
For Calgarians, the impact could be felt at the gas pump, in local businesses, and in the job market.
The city’s reliance on U.S. markets leaves little room for maneuver, making it a prime target for tariff-related pain.
3. Windsor, Ontario
Windsor’s economy is deeply intertwined with the U.S. auto industry, thanks to major assembly plants for Ford and Stellantis.
The 25% tariff on auto exports could disrupt the cross-border supply chain, leading to job losses and production delays.
“We’re talking about thousands of jobs at risk here,” says union leader Sarah Evans.
“Windsor’s auto sector is already under pressure, and these tariffs could push it over the edge.”
The report ranks Windsor third on the list, highlighting its vulnerability to trade disruptions.
For residents, this could mean higher car prices, fewer job opportunities, and a slower local economy.
4-6. Kitchener-Cambridge-Waterloo, Brantford, and Guelph, Ontario
Southwestern Ontario’s auto sector takes another hit with Kitchener-Cambridge-Waterloo, Brantford, and Guelph making the top 10.
These cities rely heavily on auto and parts manufacturing, all facing the 25% tariff.
“This region is a hub for auto innovation, but tariffs could stifle growth,” says Dr. Michael Lee, an industrial economist.
“Smaller suppliers could be forced to close, and that affects everyone from workers to consumers.”
For these communities, the impact could be devastating, with ripple effects on related industries like logistics and retail.
7. Saguenay, Quebec
Saguenay, a major player in Canada’s aluminum industry, ranks seventh on the list.
Supplying roughly a third of the country’s total production, most of which goes to the U.S., the city faces a double whammy with tariffs on both exports and steel/aluminum.
“We’re looking at a potential 50% tariff burden, which is unsustainable,” says local business leader Jean-Claude Martin.
“This could lead to plant closures and layoffs, and that’s not something our community can afford.”
For Saguenay residents, higher costs and fewer jobs could reshape the local economy, with long-term consequences for growth.
8. Hamilton, Ontario
Known as Canada’s steel capital, Hamilton is home to major producers like ArcelorMittal Dofasco and Stelco, which export steel used in auto manufacturing and construction.
With separate 25% tariffs on steel and aluminum imports announced by Trump, Hamilton’s exposure is significant.
“We’re already competing with global players, and these tariffs could tip the scales,” says Dr. Lisa Nguyen, an industrial analyst.
“This could lead to higher steel prices, affecting everything from cars to buildings.”
For Hamiltonians, the impact could mean higher construction costs, fewer industrial jobs, and a slower economy.
9. Trois-Rivières, Quebec
Trois-Rivières, another Quebec city, ranks high due to its industrial base, including paper and manufacturing. With tariffs threatening exports, the local economy could face challenges.
“We’re a small city, and these tariffs could hit us hard,” says resident Pierre Dubois.
“Businesses here are already struggling, and this could be the final blow.”
10. Lethbridge, Alberta
Rounding out the top 10 is Lethbridge, Alberta, with exposure tied to energy and agriculture exports.
The report warns that tariffs could disrupt these sectors, leading to price hikes and job losses.
“We’re a rural community, and these tariffs could make it harder for farmers to compete,” says local farmer John Smith.
“This is about more than just numbers—it’s about our livelihoods.”
The Safe Havens: Cities Less Exposed to Tariffs
While some cities face dire consequences, others are better positioned to weather the storm.
The report highlights 10 cities with lower tariff exposure, thanks to diversified trade and proximity to international markets.
Sudbury, Ontario: Ranked safest, Sudbury exports nickel and copper to global markets, reducing reliance on the U.S.
Kamloops, British Columbia: Diversified trade, especially with Asia, makes Kamloops less vulnerable.
Nanaimo, British Columbia: Coastal location facilitates trade with Europe and Asia, lowering risk.
Winnipeg, Manitoba: Balanced trade portfolio helps buffer against tariffs.
Regina, Saskatchewan: Agriculture exports to multiple markets reduce exposure.
Victoria, British Columbia: Ocean access supports international trade, minimizing risk.
Halifax, Nova Scotia: A major port city, Halifax benefits from global trade routes.
Saskatoon, Saskatchewan: Agriculture and diversified exports offer protection.
St. John’s, Newfoundland and Labrador: Fisheries and energy exports to Europe and Asia reduce U.S. dependence.
Vancouver, British Columbia: A global trade hub, Vancouver is less reliant on U.S. markets.
For residents in these cities, the tariff threat may feel distant, but the report warns that even safe havens could face indirect effects, like higher import costs or slower economic growth.
How Tariffs Could Impact All Canadians
While the report focuses on specific cities, the economic impact of tariffs could extend far beyond the most vulnerable regions.
Higher export costs could lead to price increases for consumers, from gas to cars to construction materials.
Job losses in key sectors could strain local economies, and businesses may struggle to pivot to alternative markets.
“The ripple effect is real,” says Dr. Carter.
“If Calgary’s energy sector takes a hit, it affects suppliers, retailers, and even tourism. This isn’t just about trade—it’s about livelihoods.”
The Canadian government is under pressure to respond, with potential retaliatory tariffs on U.S. goods and negotiations to mitigate the damage.
But experts warn that the long-term effects could reshape Canada’s economy for years to come.
What Can You Do Preparing for the Tariff Fallout?
If you live in one of the vulnerable cities, here are some steps to prepare:
Diversify Income: Consider side hustles or remote work to buffer against job losses.
Save More: Build an emergency fund to handle potential price hikes.
Support Local: Buy from local businesses to keep money in your community.
Stay Informed: Follow trade negotiations for updates on tariff policies.
For businesses, pivoting to alternative markets, like Asia or Europe, could help mitigate risks, but this requires time and investment.
“Adaptation is key,” says Dr. Lee.
“Companies that can diversify their customer base will be better positioned to survive.”
What Are Economists Saying?
Dr. Emily Carter, University of Toronto: “These tariffs could be a wake-up call for Canada to reduce its reliance on the U.S. market, but the transition will be painful.”
Dr. Raj Patel, University of Calgary: “Alberta’s energy sector is already struggling, and tariffs could push it to the breaking point.”
Dr. Michael Lee, Industrial Economist: “The auto sector is at a crossroads, and tariffs could accelerate the shift to electric vehicles, but not without pain.”
These insights highlight the complexity of the issue, with no easy solutions in sight.
Local Stories: How Residents Are Feeling the Pressure
To humanize the data, we spoke to residents in vulnerable cities. Here are their stories:
Mark Thompson, Saint John: “I’m worried about my job at the refinery. If tariffs hit, I don’t know what we’ll do.”
Sarah Evans, Windsor: “My husband works at Ford, and we’re already tightening our belts. Tariffs could be the last straw.”
Jean-Claude Martin, Saguenay: “Our aluminum industry is our pride, but these tariffs could crush us.”
These personal accounts underscore the human cost of trade wars, reminding us that numbers on a page represent real lives.
How Tariffs Fit Into the Bigger Picture
Trump’s tariffs aren’t just about Canada—they’re part of a broader shift toward protectionism globally.
From China’s trade disputes to Europe’s tensions with the U.S., the world is grappling with the fallout of economic nationalism.
For Canada, this means navigating a complex landscape where diversification is key but challenging.
“Canada can’t afford to put all its eggs in the U.S. basket,” says Dr. Carter.
“We need to build stronger ties with Asia, Europe, and other markets, but that takes time and investment.”
The report’s findings are a wake-up call, not just for policymakers but for businesses and citizens.
The future of Canada’s economy hangs in the balance, and the next few months will be crucial.
As Trump’s tariff pause nears its end, Canada faces a critical moment.
The BDL report highlights 10 cities on the brink, from Saint John to Lethbridge, but the impact could reach every corner of the country.
Whether you’re in Calgary worrying about gas prices or in Windsor fearing job losses, the tariff threat is real and immediate.
But there’s hope.
By diversifying trade, supporting local economies, and staying informed, Canadians can weather this storm.
The question is, will our leaders rise to the challenge, or will we be left to pick up the pieces?
One thing is clear: the next chapter of Canada-U.S. relations will shape our future for generations to come.
