The United States of America and Canada qualify as such.
Arguably, other countries and territories could be considered as such too, but can be easily disqualified:
North America is a continent. It contains such countries as Canada, the United States of America, and Mexico. A continent does not have only one leader: a continent contains many countries and each of them has its own president or prime minister.
North America has fifty states. To be more specific, the United States of America, is the country that has fifty states. North America is the continent. (The three biggest countries in North America are Canada, U.S.A, and Mexico. There are many small islands, and other small countries when getting closer to South America.)
Its in Mexico - So North America
South America and North America are continents. A continent contains a number of countries, and each of those countries has its own leader. For example, in South America, there are countries like Argentina, Peru, Brazil, and Venezuela. Each one has its own government and its own president. North America is also like that: it contains Canada (which has a prime minister), the United States of America (which has a president), and Mexico (which has a president). Thus, there is no one person who is "president of North America" or "President of South America." A continent does not have only one leader, in other words; it has as many leaders as there are countries.

Only one: North America, from which Mexico belongs to. Depending on your home country, Mexico is also considered to be part of either Central America or South America. Both instances are incorrect: Central America is not a continent, and South America includes all countries south of Panama (in fact Mexico is bordering Central America's Guatemala and Belize).
North America - USA, Canada and Mexico.
