A Canadian-American is an American of Canadian origin. The term is particularly apt when applied or self-applied to people with strong ties to Canada, such as those who have lived a significant portion of their lives in, or were educated in, Canada, and then relocated to the United States.
Since the term Canadian itself refers to a nationality rather than an ethnicity, the term cannot be considered an ethnonym. English-speaking Canadian immigrants easily integrate and assimilate into American culture and society as a result of the cultural similarities and in the vocabulary and accent in spoken English. This cultural "invisibility" within the larger US population is seen as creating stronger affinity amongst Canadians living in the US than might otherwise exist.  According to Canadian estimates the number of Americans of Canadian origin may be between 20 to 30 million, about 9% of the total US population.
As a consequence of Article 3 of Jay Treaty of 1794, official First Nations status, or in the US Native American status, also confers the right to live and work on either side of the border. But many of Canada's First Nations people identify with Canadians moreso than Americans.
There are some institutions in the United States that focus on Canadian-American studies such as the Canadian-American Center at the University of Maine  or the Center for Canadian American studies at Western Washington University. .
