Does my bankruptcy status in Canada has any legal impact on my life here in the USA?

You will have to face the consequences of filing bankruptcy, whether it was in Canada or the United States. I believe that your response was potentially less than responsive, at least in spirit. It is very interesting that they were asking regarding chapter 13 as opposed to bankruptcy.

The rule of thumb is to answer questions honestly. If the question is whether you have you ever filed for Bankruptcy under chapter 13 and you have not filed under Chapter 13 of the Bankrutcy Code (11 U.S.C. Sections 101, et seq), your answering "no" is correct. The more specific the question, the easier the answer. If the question had been whether you " have ever filed Bankruptcy", without more, your answer should probably be yes. However, note that I cannot advise one way or the other without reviewing the document you are completing and the questions around it as a Court may say that the questions before and after a particular question clarify a particular question.

That is a truthful answer.

I would contact the mortgage company and tell them that you filed a bankruptcy in Canada. You do not want to conceal anything and have it adversely affect you later on.
