It makes no sense as a single "state". We have two official languages for a reason, Quebec is Francophone and culturally distinct and very large. Other provinces (e.g. New Brunswick) are fully bilingual. We have three ocean coastlines, and a geographic mass which is the second largest country in the world. How you fit that all into one US "state" is preposterous and in fact that's probably one of the most inflammatory ignorant things about the whole way Trump speaks.
Not that we'd ever be "admitted" as a state should we be forced to grovel down to that point. We'd be some sort of occupied territory with no voting rights, but with 100% right for American capital to take our resources freely and dismantle our institutions.
BTW it's very close to California: https://en.wikipedia.org/wiki/List_of_U.S._states_and_territ...
