Before July: What the 2026 North American Trade Review Could Mean for Your Business

When trade policy hits the headlines, most small business owners tune it out. It sounds like a conversation for auto executives and federal diplomats, not for a tool-and-die shop in Windsor or a tech firm in Ottawa managing quarterly margins.

But the upcoming review of the Canada-United States-Mexico Agreement (CUSMA) is different. With the formal review set to begin in July, waiting until the final deal is on the table before paying attention is a risk many Ontario SMEs can’t afford to take.

The Exposure Is Deeper Than You Think

Most Ontario SMEs already know tariffs affect them. What is harder to see is exactly where, and how far back in the supply chain that exposure actually runs.

The obvious risks are easy to spot: a direct U.S. supplier or a cross-border input. But in our client work, the less obvious ones are often where the real pressure starts to build, software and services priced in U.S. dollars, distributor costs quietly absorbing duties and passing them through, or customers whose own U.S. exposure is starting to affect what they are willing to pay.

In a year already shaped by Buy Canadian discussions and renewed tariff concerns, Those aren’t edge cases. They’re already showing up in costs, planning assumptions, and contracts.

What’s at Stake This July

Canada has already started positioning for the review. Prime Minister Mark Carney’s government has put forward a trade team that includes Chief Negotiator Janice Charette, Trade Minister Dominic LeBlanc, and Ambassador Mark Wiseman, who recently met with U.S. Trade Representative Jamieson Greer in Washington ahead of the formal process.

A recent Boston Consulting Group report outlines three broad possibilities.

The first is a straightforward extension of CUSMA with limited changes, likely the most stable outcome for SMEs. The second is a broader renegotiation bringing new rules around digital trade, labour standards, and sector-specific requirements. The third is a shift toward separate bilateral deals between the U.S. and Canada, and the U.S. and Mexico. For businesses already operating across integrated North American supply chains, that would likely be the most complex scenario, with potentially different compliance requirements at each border.

Build a Readiness Plan, Not a War Room

BCG recommends large corporations build “tariff command centres.” For most Ontario SMEs, the principle matters more than the infrastructure. The goal is understanding where your business is vulnerable before July, not after the headlines force the question.

In our experience, the most useful place to start is with your top expenses. How many are tied to U.S. suppliers or U.S.-linked pricing? If duties or trade-related costs were to rise, what does that do to your margins? Working through that scenario now, even roughly, puts you well ahead of most businesses your size.

The next step is your contracts. Do your supplier or customer agreements give you room to adjust pricing if your costs increase? If not, you may end up absorbing the hit. This is a good time to review where your contract terms leave you exposed, especially your price adjustment and risk allocation language, and whether any updates are worth making while there’s still time to negotiate them calmly.

Finally, if you supply into the Ontario government or large municipal projects, pay close attention to the Buy Canadian angle. Washington has already flagged domestic sourcing policies as a trade irritant, and procurement-heavy sectors such as construction supply, public-sector IT, and professional services tied to government contracts could find themselves caught in the crossfire as negotiations unfold.

What to Do Before July

The 2026 CUSMA review is not just a political story. For many SMEs, it is a business planning milestone.

Review your supplier invoices. Map where your inputs actually come from. Take a close look at your contracts. That is usually where your exposure shows up first.
