The Trade War Has Come to City Hall; Municipalities Should Choose Their Weapons Carefully

The latest escalation in the Canada-U.S. trade war has brought an issue normally fought in national capitals directly to Canada’s city halls.

That is understandable. Tariffs threaten employers, jobs, and investment in communities across Canada. Municipalities face higher costs for construction materials, vehicles, equipment, and other goods, as well as a shrinking industrial tax base. What originally looked like a temporary disturbance now seems like a more significant shift in Canada’s trading environment.

In Ontario, with municipal elections this year, voters can expect candidates to offer their own ideas about how local governments should respond.

Municipal leaders should want to help. But not every response available to them is equally effective or the best use of limited municipal resources.

The starting point should be recognizing what municipalities cannot – and should not – try to do. International trade is primarily a federal responsibility, while Ottawa and Queen’s Park have fiscal resources municipalities cannot match. Municipal governments should resist trying to recreate federal or provincial industrial policy through the property-tax base.

Instead, they should concentrate on the areas where local government can make a distinctive contribution.

1) Help senior governments help local businesses

Federal and provincial governments have the capacity to provide export assistance, worker supports, and major industrial incentives. Municipal economic-development offices can help local employers understand and access those programs.

Municipalities also provide something senior governments need: timely local intelligence. They can convene tariff-exposed employers, chambers of commerce, educational institutions, and economic-development organizations, and ensure Ottawa and Queen’s Park understand what is happening on the ground.

Governments make better policy when they know which employers are delaying investments, where supply chains are breaking down, and which jobs are genuinely at risk. Municipalities do not need to design the national response to make an important contribution to it. But as the recent change in the proposed seafood tariff demonstrates, local input can fill gaps in Ottawa’s understanding of local circumstances.

2) Target relief rather than spreading it indiscriminately

This distinction will become increasingly important as candidates campaign on helping tariff-affected businesses.

Municipalities have legitimate tools available. Where demonstrably necessary, temporary tax deferrals may help otherwise viable businesses through a cash-flow crisis. Assistance can be tied to demonstrated tariff impacts, job retention, or new investment.

Broad property-tax cuts, utility-rate reductions, or infrastructure subsidies are much harder to justify, even where the law allows them. An across-the-board industrial tax reduction sounds decisive, but it is a blunt instrument. It does not distinguish between an exporter devastated by tariffs and a business barely affected by them. And every dollar of municipal tax revenue or utility revenue forgone must ultimately be absorbed through lower spending elsewhere, higher taxes and rates for others, or reduced fiscal capacity.

Municipalities should apply a simple test: Does the assistance address a demonstrated trade-related problem, and is local government the best level of government to provide it? Where municipal intervention is warranted, it should generally be targeted, temporary, and tied to a measurable economic outcome. Ideally, it should be complemented by provincial or federal financial support.

3) Make communities easier places to invest

For decades, predictable access to the enormous U.S. market strengthened Canada’s pitch to international investors. Continued trade uncertainty makes that proposition less certain, particularly for manufacturing and other trade-exposed sectors.

Municipalities cannot solve that problem. But they can make the other parts of the investment proposition more compelling.

Faster development approvals, investment-ready employment lands, adequate servicing, predictable municipal processes, and active investment facilitation can all make a difference. When a manufacturer is considering an expansion or an international company is deciding where to locate a facility, time matters. A municipality that can get to “yes” faster has something valuable to offer without writing a cheque.

Trade disruption may also create opportunities as businesses seek new suppliers, reorganize production, or establish more capacity in Canada. Municipal economic-development strategies should be ready to capture those investments. Municipalities should revitalize their trade missions and “twinning” relationships, with an eye to expand international trade.

4) Use municipal purchasing power strategically

Municipal procurement became an early focus when the tariff dispute intensified in 2025. Municipalities across Ontario, for example, looked for ways to buy Canadian and reduce reliance on U.S. suppliers. Collectively, Ontario municipalities spend more than $22 billion annually on goods and services. Their C$150 billion OMERS pension fund invests billions in U.S. assets, including bonds and treasury bills.

But the policy environment has changed. Ontario’s Municipal Buy Ontario Procurement Directive came into effect in spring 2026, requiring municipalities to prioritize Ontario and Canadian goods and services and establishing specific requirements in areas including fleet vehicles and capital infrastructure.

The question is therefore no longer simply whether to “buy Canadian.” It is how intelligently municipalities can use procurement, within the provincial framework, to strengthen Canadian economic resilience.

That requires moving beyond slogans about banning American suppliers. Canadian alternatives do not exist for everything municipalities buy. The Association of Municipalities of Ontario (AMO) has rightly cautioned that procurement restrictions can increase costs and delay infrastructure where domestic suppliers are unavailable or unable to meet demand.

The better objective is supplier development. Municipalities can give Canadian businesses better information about future capital plans and procurement pipelines, including potential acceleration of public projects. Predictable demand can help suppliers determine whether investments in new capacity are commercially viable. Municipalities and the province can also identify areas of common dependence on foreign suppliers where public-sector demand might support Canadian alternatives.

The goal should not simply be to replace an American supplier today, but to help create competitive Canadian supply chains for tomorrow.

5) Build resilience rather than pursue retaliation

There is an important difference between reducing dependence on American supply chains and punishing American investment in Canada.

A U.S.-owned manufacturer employing hundreds of Ontario residents is part of the local economy. Municipal policy should be designed around Canadian jobs, investment, and productive capacity, not the nationality of a company’s shareholders.

The same principle should inform procurement in both goods and services. Where Ontario and Canadian alternatives are competitive and available, municipalities should buy them. Where they are not, the goal should be to understand the gap and help build Canadian capacity rather than accept indefinitely higher costs or poorer service simply to make a political point.

Above all, municipalities should resist designing their response around the assumption that the disruption will soon pass. The particular tariffs may change, and negotiations will continue. But Canadian governments, businesses, and investors can no longer assume the U.S. market will always operate with the predictability they once expected.

Ontario municipalities have rightly said they want to be part of a Team Canada response. Ontario’s Big City Mayors has emphasized the threat tariffs pose to local industries while supporting a coordinated Canadian position. AMO has similarly emphasized municipalities’ role in responding to the economic consequences of the dispute.

They should be part of that response. But being part of Team Canada does not mean every player performs the same job.

Ottawa should negotiate. Senior governments should provide assistance at the scale required to support major industries and workers. Municipalities should convene, connect businesses with assistance, use their purchasing power strategically, help develop Canadian suppliers, target relief where it can change outcomes, and make it easier to invest.

Do the right thing, not just the thing at hand

With a municipal election approaching, the temptation to demonstrate action will only grow. Mayoral rivals in major Ontario cities are already debating property tax deferrals, waiving interest penalties and other actions.

In the BBC’s brilliant 1980’s political satire “Yes, Minister,” the wily Sir Humphrey Appleby described the faulty logic of being pressured to act in a crisis:

“Something must be done. This is something. Therefore, we must do it.”

The better test is whether the “something” will work. In a trade war, it is not any action, but the right action, that matters.
