From context, I'm guessing you mean Canada. "Ca." is an abbreviation for California, which is how I first read it. I've never seen Canada abbreviated to "Ca." The ISO 3166-1 alpha-2 code for Canada is CA (all caps, no period), although it also ambiguously refers to California.

"Can." (or CAN or CDN), to be less ambiguous, but simply spelling it out isn't much effort to avoid confusion.
