Immigration lawyer Gabriela Ramo says that under Canadian law, someone’s citizenship can only be revoked if it can be proven that they committed fraud or misrepresentation to obtain it.

“Before they could move to do this, they would need to introduce legislation, there would have to be amendments to the current Citizenship Act,” said Ramo, former chair of the Canadian Bar Association’s immigration section. “There’s no provision that would allow them to pursue revocation of citizenship of a Canadian birth, by virtue of his birth to a Canadian mother.”
