The term "American-Canadian" is quite specific, referring to individuals who are both American and Canadian. However, there are other ways to describe those with dual citizenship or those who identify with both cultures. Some synonyms could include "dual-national," "bi-national," "transnational," or "binationalist." Additionally, one could simply use terms like "Canadian-American" or "American-Canadian" depending on which country they feel more closely connected to. Other options might be to use terms like "North American" or "continental" to describe someone who identifies as connected to both countries equally. Ultimately, the best language will depend on the individual and the context in which the term is being used.
