What if Canada, the United States, and Mexico built something more than a trade agreement — a true economic union, and one day, perhaps, a common currency?
Explore the Case Read the ChallengesNorth America is already one of the most economically intertwined regions in the world. A car assembled in Ontario carries parts from Michigan and Coahuila. Energy, food, capital, and ideas cross our two borders every hour of every day. Yet our institutions haven't caught up to our reality: we cooperate deal by deal, agreement by agreement, always one election or one tariff away from friction.
This site makes the case for something more durable — a North American union, built gradually and by consent, that deepens the common market we already have, eases the movement of goods, services, and eventually people, and one day opens the door to a shared currency. Not a merger of countries. Not the end of the maple leaf, the stars and stripes, or the eagle and serpent. A partnership of three sovereign democracies, choosing to build shared prosperity the way Europe did — step by patient step.
In 2025, U.S. trade in goods with Mexico reached roughly $873 billion, and trade with Canada roughly $719 billion — together about $1.6 trillion a year, with Mexico standing as America's single largest trading partner. Canada and Mexico absorb roughly a third of all U.S. goods exports. Supply chains in autos, aerospace, agriculture, and energy don't stop at the border; they are the border, crossed thousands of times a day.
But this deep integration rests on a fragile foundation: trade agreements that must be renegotiated, reviewed, and re-fought every few years, and that recent tariff disputes have shown can be strained overnight. Businesses can't plan decades ahead when the rules might change with the next political cycle. Workers whose livelihoods depend on continental supply chains bear the cost of every trade war.
A union would replace this permanent uncertainty with permanent architecture — shared institutions, predictable rules, and a common voice in a world increasingly organized around large blocs: the European Union, a rising Asia, and others. North America competes best when it competes together.
A true common market — with harmonized standards, open competition, and eventually a shared currency — would cut costs for businesses, eliminate exchange-rate risk on continental trade, and give North America the scale to out-compete any bloc in the world. The euro did exactly this for European commerce: one price, one currency, no conversion friction across member economies.
Even under USMCA, border delays, customs paperwork, and regulatory duplication cost billions each year. A customs union with common external tariffs and streamlined internal borders would let goods move as freely from Monterrey to Montreal as they do from Texas to Tennessee — securing the supply chains our industries already depend on.
Europe's citizens can live, work, and study across 27 countries. Imagine a North America where an engineer in Guadalajara, a nurse in Winnipeg, and a builder in Phoenix could answer opportunity wherever it arises — with orderly, legal mobility replacing today's broken patchwork. Labor mobility is also one of the key ingredients that makes a currency union work.
Seventy-five years ago, the idea of France and Germany sharing a market — let alone a currency — seemed fantastical. They had fought three wars in as many generations. Yet Europe built its union not in one leap but in deliberate stages, each one earning trust for the next.
Six nations pool control of two strategic industries. Small start, profound principle: shared interests make conflict unthinkable.
The European Economic Community is born — a common market with the free movement of goods at its heart.
Free movement of goods, services, capital, and people across member states becomes reality.
A shared currency launches, first electronically and then as cash. Today 21 countries and roughly 350 million Europeans use the euro daily — Bulgaria became the newest member in January 2026.
For all its stresses and setbacks, the EU remains history's most ambitious peaceful integration of sovereign states — and the template North America can learn from, adapt, and improve on.
North America starts from an easier place than postwar Europe did: two land borders instead of dozens, three countries instead of twenty-seven, longstanding peace, deeply linked industries, and decades of experience under NAFTA and USMCA. The question is not whether integration is possible — we live it daily — but whether we choose to give it lasting form.
Advocacy that ignores the hard parts isn't advocacy; it's salesmanship. A North American union faces serious obstacles, and the case for it is only credible if it takes them seriously.
Canadians, Americans, and Mexicans are rightly proud of distinct national identities, and none wants to be absorbed by a neighbor. Any union must be built on the EU's core insight: member states remain sovereign nations that pool specific, limited powers by treaty — and Europe's own debates (including Brexit) show how carefully that balance must be struck and maintained.
Wage and income gaps between Mexico and its northern neighbors are substantial — larger than most gaps inside the EU at its founding, though the EU later absorbed similar disparities with its eastward expansion. Convergence takes decades and deliberate investment, and moving too fast on labor mobility or a currency before economies converge would strain the union rather than strengthen it.
A single currency means a single monetary policy — and the eurozone debt crisis of the 2010s showed what happens when one interest rate must fit very different economies without shared fiscal tools. A North American currency should come last, not first, and only with the fiscal architecture the euro initially lacked.
Recent years have brought tariffs and trade tensions between the three countries — a reminder that integration can move backward as well as forward. That is an argument for stronger institutions, not weaker ones, but it means the near-term work is rebuilding trust, not drafting treaties.
A union means pooling specific, enumerated powers — trade rules, customs, perhaps eventually monetary policy — while each country keeps its own government, constitution, laws, military, and identity. EU member states remain fully sovereign nations; France did not stop being France. Any North American union would be created by treaty, ratified democratically in all three countries, and revocable by its members.
Not soon — and it shouldn't be the first step. Economists who study currency unions point to prerequisites: deeply integrated trade (which North America has), synchronized business cycles, labor mobility, and shared fiscal backstops (which it mostly lacks). The euro took four decades of prior integration to arrive, and its early design flaws caused real pain. A North American currency is best understood as a possible capstone decades out, not a starting point.
USMCA is a trade agreement: valuable, but limited in scope and subject to periodic renegotiation and political reversal. A union adds durable shared institutions — think a customs union with common external tariffs, standing bodies to harmonize regulations, dispute resolution that doesn't depend on the political weather, and a long-term roadmap toward deeper stages that each country opts into as trust grows.
Full mobility would come late in the process, as it did in Europe — and even the EU phased in labor access for new members over transition periods of up to seven years. Earlier stages could focus on orderly, credential-recognized mobility for specific sectors facing shortages. Notably, when the EU expanded eastward, feared mass migrations were smaller than predicted, and rising prosperity at home eventually slowed emigration from newer members.
They proved that design matters. The euro crisis exposed the risk of monetary union without fiscal union; Brexit showed that public consent must be continually earned, not assumed. A North American project can learn from both: sequence integration carefully, build in democratic accountability from the start, and never let the project outrun the people's support. It's worth noting the EU itself survived both crises, and no eurozone country has left the currency.
Deeper North American integration has been discussed for decades by economists, business leaders, and policy thinkers across all three countries and across the political spectrum — though a full union with a common currency remains a minority position today. This site exists to move that conversation forward: to make the long-term case openly, acknowledge the obstacles honestly, and invite serious debate.
Europe began with coal and steel. North America can begin with the integration we already live — and the imagination to give it lasting form.
