During a dinner discussion over border policy last Friday, U.S. President-elect Donald Trump joked with Canadian Prime Minister Justin Trudeau that Canada could become the “51st state” if it didn’t like proposed 25% tariffs.
While the comment was dismissed as a jest by delegates, it has reignited discussion around an idea that has never gained serious traction—and likely never will.
Political Imbalance: The Key Obstacle
Annexing Canada, with its population of 40 million, would fundamentally shift U.S. politics:
- Leftward Tilt: Canadians lean significantly left of their American counterparts on issues like abortion and gun rights. Even traditionally conservative provinces like Alberta would likely favor Democrats.
- Presidential Preferences: Polls consistently show Canadian support for Democratic candidates. A recent survey by the Environics Institute found 44% of Prairie residents preferred Kamala Harris over Trump’s 33%.
Annexation would likely cement Democratic dominance in U.S. politics for at least a generation, making it an unappealing prospect for Republican leaders.
Historical Reluctance to Accept New States
The U.S. has a long history of carefully balancing political power when admitting new states:
- Alaska and Hawaii (1959): These were admitted together to balance Democratic and Republican influence, a strategy that would be nearly impossible to replicate with Canada.
- Puerto Rico: Its statehood ambitions remain blocked, largely due to its potential to tip the balance of power toward Democrats.
Trump even joked that Canada could enter as two states—one liberal and one conservative—but such a division would require extreme gerrymandering, making it impractical.
Joining the United States is a one-way ticket:
- Unlike Canada, where the Clarity Act allows provinces to secede under certain conditions, U.S. membership is irrevocable.
- The American Civil War definitively settled that states cannot leave the Union, regardless of political or regional grievances.
Even U.S. expansionists have noted a lack of interest in annexing Canada. In the 1980s, L. Craig Schoonmaker, a proponent of U.S. expansionism, remarked that “apathy,” not Canadian nationalism, was the primary reason annexation had never been pursued.
Despite Trump’s lighthearted comment, historical, political, and logistical barriers make Canada’s inclusion as a U.S. state highly improbable. For now, Canada’s maple leaf will remain proudly independent.
