I was wrong about the one year. In this article Cruz’s campaign said the moved there in 1967. The law in Canada at that time said you had to live there for 5 years to apply for citizenship so there is no way in 1970 she could have been a citizen.

I should have been more thorough in my comment. If they expedited Raphael Cruz as a Cuban refugee his wife could have received her citizenship through the same action. There is no evidence that she did or did not which is why the consular form or the documentation submitted for Senator Cruz’s passport would clear up the misunderstanding.
Sadly I believe Ted Cruz wants to keep the issues cloudy because he knows that he is not a natural born citizen the more clear the facts become the harder it will be to blow past the issue.
