CUSMA at a Crossroads: 5 Legal Protections Canadian Businesses Need Before July 1

With Canada's most critical trade relationship hanging in the balance, the clock is ticking for Canadian businesses. Donald Trump has made clear he is "not looking to renew" the Canada-United States-Mexico Agreement (CUSMA) when it reaches its mandatory review on July 1, 2026 — just ten days away. The deal underpins more than $1.3 trillion in annual cross-border trade and shields approximately 90 per cent of Canada's exports from U.S. tariffs.

While trade officials on both sides of the border continue negotiations, Canadian business owners face a more immediate challenge: what legal protections can you put in place right now, before the deadline arrives?

What the July 1 CUSMA Review Actually Means for You

CUSMA — known in the U.S. as USMCA and in Mexico as T-MEC — entered into force on July 1, 2020, replacing NAFTA. It includes a mandatory joint review after six years, bringing all three countries back to the table this July 1.

If the three governments agree to extend the deal, CUSMA continues for another 16 years. If they do not — and Trump has said he would "rather not have USMCA" — the agreement does not automatically expire. It remains in force while renegotiation continues. However, uncertainty around future tariff schedules, labour mobility rules, and intellectual property protections creates real legal exposure for any Canadian company with U.S. ties.

Canada's Trade Minister Dominic LeBlanc has confirmed Ottawa is pushing for full renewal. Most trade analysts believe Trump is using non-renewal threats as a bargaining tactic. But in contract law, uncertainty is not a defence — and what happens at the negotiating table this summer could affect your agreements starting August 1.

Why Your Business Contracts May Be Exposed Right Now

Cross-border contracts drafted before 2025 typically assumed stable CUSMA tariff schedules. A review outcome — even a partial renegotiation — can trigger several hidden legal vulnerabilities:

Tariff pass-through clauses. Supply agreements often specify who bears unexpected tariff increases. Ambiguous language here means Canadian exporters can end up absorbing U.S. tariff costs that were never priced into the deal.

Force majeure provisions. Does your contract define a trade policy shift as a force majeure event? Canadian and U.S. courts have reached different conclusions on this question, and the answer determines whether either party can exit the contract without penalty.

Intellectual property protections. CUSMA strengthened IP rules on both sides — longer copyright terms, tighter trade secret protections. If the agreement is renegotiated and those chapters change, registered and unregistered protections you currently rely on may not transfer automatically.

Labour mobility under TN visas. CUSMA created streamlined U.S. work permits for Canadian professionals in dozens of categories, from engineers to accountants. A renegotiated agreement could change eligibility rules with little notice, affecting any employee you currently have working south of the border.

These are live contractual vulnerabilities — and a business lawyer can audit your key agreements in a matter of days.

5 Legal Protections to Put in Place Before July 1

1. Commission a contract audit. Ask a business lawyer to review your main U.S. client and supplier agreements for tariff exposure, force majeure gaps, and dispute resolution clauses. Prioritize any contract that renews automatically around July 1.

2. Insert a trade policy risk clause. Work with legal counsel to add language that allocates risk between parties if CUSMA terms materially change. A well-drafted clause specifies which tariff schedules the contract relied upon and what happens if duties rise above an agreed threshold.

3. Document your rules of origin. CUSMA's preferential tariff rates apply only to goods that meet defined Canadian-content thresholds. If your products cross the border, a lawyer can help you document content levels now — so you are not scrambling to prove compliance if customs scrutiny increases after July.

4. Audit your TN visa holders. If Canadian employees work in the U.S. on TN status, ensure their petition categories are well-documented and that role descriptions match current job functions. Clean paperwork today protects your team regardless of what the renegotiation produces.

5. Register your IP on both sides of the border. CUSMA harmonized several intellectual property rules. Filing or renewing Canadian and U.S. registrations now — before any potential rollback of the agreement's IP chapter — ensures your protections hold regardless of the review outcome.

When Does a Business Actually Need a Lawyer?

Not every Canadian company faces urgent legal action. But you likely do if any of the following apply:

• More than 20 per cent of your revenue comes from U.S. clients or is priced in USD
• You have employees working in the U.S. on TN professional visas
• You have supply, distribution, or licensing contracts that reference CUSMA tariff schedules
• You hold patents, trademarks, or trade secrets registered only in Canada or only in the U.S.
• Key contracts renew automatically between July and December 2026

For companies in manufacturing, agri-food, professional services, or technology — sectors that rely heavily on cross-border trade — a legal review before July 1 is not optional. It is risk management.
