Imagine the logistics and legal battle Canada would face if they revoked 5 million citizens and passports.
It would go directly against their current laws that make it impossible to revoke citizenship, even from terrorists. Would it surprise me if this gov't treated convicted terrorists better than Albertans? No, it wouldn't.
Exhibit A -
Tahawwur Hussain Rana: Naturalized Canadian citizen (2001). Convicted in the U.S. for supporting the 2008 Mumbai terrorist attacks (166 killed); facing charges in India.
