Manitoba Premier Wab Kinew has left little ambiguity about where his government stands after Canada’s latest trade talks with the United States collapsed. With new U.S. tariffs taking effect and Prime Minister Mark Carney ordering Canadian negotiators home, Kinew said Manitoba was behind Ottawa “100 per cent” and welcomed the decision to reject terms he considered a bad deal.
The confrontation is also accelerating a second economic strategy that has been building for more than a year: making it easier for Canadian companies to do business with other Canadians. For Manitoba, where the United States remains overwhelmingly important to exporters, interprovincial trade cannot simply replace the American market. But new federal and provincial laws, Canadian procurement preferences and growing pressure from businesses are turning the domestic market into a much more important part of Canada’s response.
Kinew Makes Manitoba’s Position Unmistakable
Kinew’s response came after Carney held a virtual meeting with provincial and territorial premiers on August 22 to explain why the federal government had suspended negotiations with Washington. Speaking afterward in Winnipeg, Kinew said Manitoba was “100 per cent” behind the prime minister’s direction and that Ottawa had been right to walk away. He described the proposed agreement as one Canada should not have accepted and argued that giving ground under pressure would only invite additional demands. The political message was unusually clear for a federal-provincial relationship in which premiers routinely disagree with Ottawa over taxes, transfers, health care and regulation.
The support also went beyond Manitoba. Other premiers publicly backed Carney after the negotiations collapsed, while the federal readout of the first ministers’ meeting emphasized unity and continued collaboration. For Kinew, that unity is becoming part of the economic response itself. His argument is that Canada cannot control decisions made in Washington, but governments inside Canada can control how aggressively they support domestic businesses, remove barriers and redirect purchasing toward Canadian suppliers. That makes the dispute about more than tariffs; it is becoming a test of whether provinces can operate more like pieces of one national market.
Carney’s Walkout Came After a Deal Appeared Close
Only days earlier, Canada and the United States seemed to be approaching an agreement. Negotiators had been discussing lower tariff levels on strategically important industries, including steel, aluminum and vehicles, while Canadian provinces had been asked to consider returning American alcohol to their liquor-store shelves. Ottawa was also prepared to make administrative changes connected to supply management without dismantling the system itself. The possibility of a compromise was real enough that provincial governments had been preparing for what a deal could mean.
Carney said the situation changed when Washington introduced new terms late in the process. According to the prime minister, those demands were economically unattractive and raised broader questions involving Canada’s ability to pursue its own trade relationships, industrial policies, culture and language. His summary was that the United States had asked too much while offering too little. Reuters reported that disagreements also included the treatment of Canadian-made medium- and heavy-duty vehicles. Instead of accepting a package Ottawa believed could weaken Canadian industries or restrict future policy choices, Carney ordered the negotiating team home. That decision is the walkout Kinew is now defending.
The Tariff Fight Has Entered a More Confrontational Phase
The immediate consequence is another round of tariffs. Ottawa said the latest U.S. measure imposed duties of 50 per cent on roughly $28 billion worth of Canadian goods. Reuters calculated the affected trade at about $20 billion using its assessment of the products covered, illustrating how estimates vary depending on valuation and classification. Products affected include consumer and manufactured goods ranging from wine and furniture to clothing, cement and hockey equipment. The new measures add to sector-specific restrictions that Canadian steel, lumber and automotive producers have already been navigating.
Canada has promised a dollar-for-dollar response beginning September 8. Ottawa says its counter-tariffs will be concentrated in areas including steel, dairy products, appliances, agricultural equipment, pulp and paper, and electronics. That delay creates a short window before the Canadian measures take effect, but there was no new negotiating round scheduled immediately after the collapse. The significance therefore goes beyond the products on the tariff lists. Canada and its largest trading partner have moved from trying to contain a dispute toward preparing businesses and workers for the possibility that elevated trade friction could persist.
Manitoba Has More at Stake Than Most Consumers See
For Manitoba, the American market is difficult to replace simply because of its scale. Provincial figures show Manitoba exported about $14.5 billion in merchandise to the United States in 2024, representing more than 70 per cent of its international goods exports. Manitoba officials have recently described the normal share as roughly 70 to 75 per cent. Geography reinforces that relationship: manufacturers, agricultural processors and transportation companies have spent decades building supply chains that connect Manitoba directly with nearby American states.
The dependence is visible in more recent numbers. Manitoba’s economic dashboard reported $4.94 billion in U.S.-bound exports year-to-date through May 2026, down 18.9 per cent from the comparable period a year earlier. Statistics Canada has also found that 95.3 per cent of Manitoba establishments that exported goods in 2024 sold something to the United States, the highest share among the provinces. Kinew said only about four per cent of Manitoba’s exports would be directly exposed to this newest 50 per cent tariff package, but that figure does not capture the province’s wider vulnerability to existing sectoral tariffs, investment uncertainty or future escalation.
Manitoba Is Already Redirecting Government Purchasing
Kinew’s government is not beginning its buy-Canadian strategy from scratch. Manitoba introduced legislation in 2025 allowing provincial purchasing policies to favour Canadian suppliers, and the Buy Canadian Act officially came into force on July 1, 2026. Kinew told reporters that provincial spending with U.S. companies had already been cut by more than 80 per cent since the trade confrontation intensified. He said Manitoba would continue favouring Canadian businesses when tendering contracts rather than easing that approach after the latest negotiations failed.
American alcohol provides the most visible consumer example. Provinces originally removed U.S. liquor from shelves as part of Canada’s response to earlier tariffs, and returning those products had become a bargaining point during negotiations. Manitoba had been open to changing course if a satisfactory agreement emerged. After the walkout, Kinew said the province would not resume ordering U.S. alcohol anytime soon. The economic importance of liquor alone is limited compared with industrial trade, but the symbolism is powerful: provincial purchasing power, government procurement and consumer choices are increasingly being treated as tools in a broader strategy to keep more spending inside Canada.
Manitoba Has Already Built an Internal-Trade Framework
The renewed interest in trading east and west comes at a useful moment for Manitoba because the province has already enacted legislation aimed at removing domestic barriers. Its Fair Trade in Canada law created a mutual-recognition system under which goods and services that meet the rules of participating Canadian jurisdictions can, subject to exceptions, be recognized as satisfying comparable Manitoba requirements. British Columbia, New Brunswick, Nova Scotia and Ontario were among the first jurisdictions included when the rules began operating in 2025.
The framework expanded again in June 2026. Manitoba added Alberta, Saskatchewan, Quebec, Newfoundland and Labrador, Prince Edward Island, the three territories and the federal government as reciprocating jurisdictions for goods. The distinction matters because recognition for some jurisdictions currently extends more broadly than for others, and exemptions remain in areas covered by domestic trade agreements or provincial health, safety and other public-interest rules. Still, the direction is unmistakable. Manitoba has moved from discussing internal trade reform to building a legal mechanism designed to reduce duplicated approvals. Kinew’s latest promise that Manitoba will be ready when other provinces “lean more into” domestic trade therefore rests on rules that are already operating.
Ottawa Has Removed Its Own Layer of Domestic Trade Barriers
The federal government has been pursuing a parallel strategy. The One Canadian Economy Act received royal assent in June 2025, and its Free Trade and Labour Mobility provisions came into force on January 1, 2026. The framework allows qualifying provincial or territorial requirements for goods and services to be recognized as satisfying comparable federal requirements for interprovincial commerce. It also provides a path for workers holding provincial or territorial qualifications to receive equivalent authorization more easily in federally regulated occupations.
There is an important limitation: Ottawa cannot unilaterally erase provincial rules. The federal legislation removes duplication arising from federal requirements, while provinces and territories remain responsible for many occupational licences, product standards, procurement rules and other barriers. That is why Kinew’s position matters. A single Canadian market requires provinces to participate rather than waiting for Ottawa to solve the problem alone. Carney highlighted the same strategy in his August 22 remarks, saying the federal government had removed its federal barriers and was working with provinces and territories on what remained. The Trump dispute is now adding urgency to a reform process that otherwise could have taken years.
The Potential Domestic Market Is Much Larger Than It Looks
Interprovincial commerce is already a major part of Canada’s economy. Statistics Canada estimates that approximately $527 billion worth of goods and services move between provinces and territories annually, equal to about 17 per cent of national GDP. Earlier Statistics Canada work found that services account for more than half of these internal flows. The domestic market is therefore not a hypothetical alternative waiting to be invented; hundreds of billions of dollars are already moving across provincial borders every year.
What governments are trying to reduce is the extra cost created by different regulations, licensing systems and administrative requirements. The International Monetary Fund estimated in its 2026 analysis that non-geographic barriers inside Canada were equivalent, on average, to a tariff of roughly nine per cent. Its modelling suggested that eliminating those barriers could eventually raise real GDP by nearly seven per cent, or around $210 billion in 2025-dollar terms. Those figures are model-based long-term estimates, not guaranteed short-term gains. But they help explain why internal trade has moved from an obscure federalism debate to an economic priority: even capturing part of that potential could improve productivity and resilience.
Manitoba Businesses Already Trade Across Provincial Lines
Manitoba also begins this push with a stronger interprovincial footprint than might be assumed. Statistics Canada found that 48.8 per cent of Manitoba businesses surveyed had purchased goods or services from suppliers in another province or territory during the previous 12 months. Another 29 per cent had sold to customers elsewhere in Canada. Those figures indicate that many companies already understand how to operate across provincial borders, even if regulations and administrative requirements can make expansion more complicated.
That existing activity helps explain the Winnipeg business community’s reaction to the latest U.S. confrontation. Winnipeg Chamber of Commerce CEO Loren Remillard argued that Canada should focus on what it can control inside its own borders and accelerate the removal of remaining barriers. He described the opportunity as creating a genuine single market of roughly 41 million people rather than allowing provincial differences to fragment demand. For a Manitoba manufacturer or professional-services company, easier access to Ontario, Alberta, Quebec or British Columbia will not recreate the size and proximity of the U.S. economy. It can, however, create additional customers and reduce the risk of having too much business dependent on one foreign market.
Internal Trade Is a Cushion, Not a Replacement for America
The strongest case for internal trade is also the one that avoids overstating what it can accomplish. Manitoba cannot redirect more than 70 per cent of its international exports into other provinces overnight. Some goods are produced specifically for U.S. customers, while transportation networks, contracts and manufacturing supply chains have been built around north-south commerce for generations. Even after years of diversification efforts, the United States remains the dominant destination for Canadian exports as a whole.
The Bank of Canada’s July outlook, prepared before this newest tariff shock, already showed why adjustment takes time. The Bank said Canadian exports remained on a lower path than before the U.S. tariff campaign began, even as businesses adapted their production and supply chains and sought new customers. Manitoba’s strategy is therefore better understood as diversification than substitution. More east-west commerce can give businesses additional demand, while overseas agreements and infrastructure can create other options. But U.S. trade will remain economically important. The policy objective is to make disruption in Washington less capable of determining the fate of a Manitoba factory, farm or transportation company on its own.
The Next Test Is Whether Political Unity Produces Practical Results
Kinew’s support for Carney may be politically striking, but businesses will judge the response by what happens next. The premiers and prime minister agreed to continue working on internal trade, export diversification and national infrastructure after their August 22 meeting. Kinew said he expected additional federal and provincial support measures for affected Manitoba industries to be discussed in the coming days. Manitoba already has a three-year, $18.2-million Canada–Manitoba Workforce Tariff Response Program intended to assist tariff-affected workers and employers, with federal officials saying it is expected to help more than 2,100 workers develop new skills.
The larger challenge will be maintaining momentum after the immediate crisis fades. Mutual-recognition laws mean little if businesses still face practical barriers, and buy-Canadian policies are most useful when domestic suppliers can compete on price, scale and reliability. Yet the latest confrontation has changed the incentive structure. Every unpredictable tariff makes the cost of Canadian economic fragmentation harder to justify. Kinew’s “100 per cent” backing of Carney is therefore only one part of the story. The more consequential development may be provinces increasingly deciding that when access to their biggest foreign market becomes uncertain, trading more freely with one another is no longer optional economic housekeeping.
