As you know, CBSA is the organization charged with the responsibility of determining admissibility into our country. If that is still an offence, if that person was found criminally responsible for whatever action, yes, they would be inadmissible to our country, because in determining whether someone is admissible, we're looking at the criminal record that's being held by the United States and determining whether that is in fact a crime in Canada.
