Can President Trump Rename Lake Ontario? The Legal Limits of “Lake America”

How federal geographic-naming law, presidential authority, and the Tenth Amendment determine who must recognize a new geographic name.

On August 27, 2026, President Donald Trump signed Executive Order 14422, directing the federal government to rename Lake Ontario as “Lake America.”

The decision quickly generated disagreement on both sides of the United States–Canada border.

Canadian Prime Minister Mark Carney rejected the designation, while New York Governor Kathy Hochul announced that New York would continue using the name Lake Ontario.

Approximately 52% of the lake's surface area lies within Canada, with the remainder bordering New York.

Although the controversy involves the name of a geographic landmark, it raises a broader legal question about the limits of presidential authority over federal agencies, state governments, and private organizations.

The Legal Question

Can the President rename a geographic feature by executive order, and does that order have any binding legal effect on state governments, foreign governments, or private entities?

Answering that question requires examining the statutory framework governing geographic names, the legal scope of executive orders, and the constitutional division of authority between federal and state governments.

The Governing Law

1. Congress Has Established a Federal Geographic-Naming System

The federal government has long maintained a formal process for standardizing geographic names.

Under 43 U.S.C. § 364, the Secretary of the Interior, acting jointly with the U.S. Board on Geographic Names, is responsible for maintaining uniform geographic nomenclature throughout the federal government.

Section 364b authorizes the Board, subject to the Secretary's approval, to establish geographic-naming principles, policies, and procedures and determine standard names for official use.

Importantly, the statute also authorizes the Secretary to act when the Board has not acted within a reasonable time.

These provisions establish the governmental framework through which official federal geographic names are determined.

Read 43 U.S.C. §§ 364–364b.

2. Federal Naming Decisions Are Binding Standards for Federal Publications

The geographic-naming statute also addresses the scope of official naming decisions.

Under 43 U.S.C. § 364e, geographic-naming decisions and principles issued by the Secretary of the Interior serve as the standard for materials published by the federal government.

President Trump's Executive Order 14422 directs the Secretary of the Interior, in coordination with the Board on Geographic Names, to implement the new designation.

The order specifically directs the updating of the Geographic Names Information System and the adoption of the new name in federal agency maps, contracts, documents, and communications.

The order expressly requires implementation consistent with applicable law.

Consequently, federal agencies are directed to use “Lake America” in their official records and publications.

But the statute's scope is significant.

Section 364e establishes naming standards for federal government publications. It does not itself require state governments or private entities to adopt those names.

3. The Tenth Amendment Limits Federal Commands to State Governments

The question becomes more complicated if the federal government attempts to compel New York State to adopt the new designation.

The Supreme Court has repeatedly recognized constitutional limitations on federal efforts to direct state legislative and executive action.

Three decisions are particularly relevant.

New York v. United States, 505 U.S. 144 (1992)

The Supreme Court held that Congress cannot directly compel states to enact or administer a federal regulatory program.

The decision reflects the constitutional principle that states retain governmental authority independent of the federal government.

Printz v. United States, 521 U.S. 898 (1997)

The Supreme Court held that the federal government cannot require state executive officials to implement a federal regulatory program.

The case involved federal legislation requiring state and local law enforcement officers to conduct background checks on prospective handgun purchasers.

The Court concluded that Congress could not compel state executive officials to perform those federal responsibilities.

Murphy v. National Collegiate Athletic Association, 584 U.S. 453 (2018)

The Supreme Court reaffirmed the anti-commandeering doctrine, invalidating a federal statutory provision that prohibited states from authorizing sports gambling.

The decision explained that Congress cannot simply issue direct commands requiring state governments to exercise their legislative authority in a specified manner.

Together, these cases establish important limits on the federal government's ability to direct state governmental operations.

None of these decisions specifically concerns the naming of geographic features. Nevertheless, their principles could become relevant if federal officials attempted to require New York to modify state maps, signage, publications, or other official records.

Does New York Have to Recognize “Lake America”?

Under the existing executive order, New York is not expressly directed to adopt the new designation.

The order addresses federal agencies and the federal geographic-naming system.

New York's continued use of “Lake Ontario” in state publications would therefore present a different legal issue from a federal agency's obligation to follow the executive order.

If federal officials subsequently attempted to compel New York agencies to use “Lake America,” the state's attorneys could potentially invoke both the geographic-naming statutes and constitutional federalism principles.

A statutory argument could focus on the limited scope of 43 U.S.C. § 364e.

A constitutional argument could rely on the anti-commandeering principles established in New York, Printz, and Murphy.

Whether those principles would control a particular dispute would depend on the nature of the federal requirement being challenged.

Importantly, no such requirement imposed on New York is established by Executive Order 14422 itself.

What About Canada and Private Mapping Companies?

The federal naming statute does not confer authority on the President to prescribe official geographic names for the Canadian government.

Canada therefore remains free to use Lake Ontario in its governmental publications.

Similarly, private mapping companies are not generally required by the cited federal geographic-naming statute to adopt every name used in federal publications.

Companies may voluntarily use federal geographic data or follow federal naming conventions, but voluntary adoption is distinguishable from a legal obligation imposed by statute or regulation.

The distinction illustrates a fundamental principle: a geographic name may be officially recognized by one government without becoming legally mandatory for other governments or private organizations.

Why This Distinction Matters

The Lake America controversy illustrates how a relatively straightforward executive action can implicate several independent sources of legal authority.

Congress establishes a statutory system for federal geographic names.

The President may direct executive agencies to implement naming policies within the limits of lawful presidential authority.

State governments retain constitutional protections against certain forms of federal compulsion.

Foreign governments remain outside the domestic legal authority of American executive orders.

The resulting distinction is between establishing a name for official federal use and compelling other entities to recognize that name.

Those are not necessarily the same governmental power.

If you represented New York State and federal officials attempted to compel state agencies to replace “Lake Ontario” with “Lake America,” what would be your strongest legal argument?

Would you begin with the statutory limitations of 43 U.S.C. § 364e, the Tenth Amendment's anti-commandeering doctrine, or a different source of authority?
