As the deputy outlined, we don't have authority under the Citizenship Act to seize a document, but we may well under the Immigration and Refugee Protection Act. If there is something we can link to immigration—and that's often the case—then we may be able to seize the document under that authority.
It may be done by one of our immigration officers, and within our department the immigration officers and citizenship generally are co-located. However, if it needs to go to CBSA, in some instances we're co-located, but more often than not, we're not.
