"The new law divides Canadians into two classes of citizens: first class Canadians who hold no other citizenship, and second class Canadians – dual citizens, who can have their right to live in Canada taken away from them. Even if you are born in Canada, you are at risk of losing citizenship if you have dual citizenship or the possibility of dual citizenship. You may not even know that you possess another citizenship. If you have a spouse, parent, or grandparent who is a citizen of another country, you may have a right to citizenship without ever having applied for it. The proposed law would put you at risk of losing your Canadian citizenship if the Minister asserts that you possess or could obtain another citizenship. The burden would be on you to prove otherwise to the Minister’s satisfaction.
The new law will make it easier for the government to take away your citizenship in the following ways:
1. For all naturalized citizens, a federal government official can revoke your citizenship if he believes you never intended to live in Canada. This could happen if you decide to study in, accept a job in, or reside in another country. In contrast, Canadian citizens born in Canada cannot lose their citizenship by living outside of Canada.
2. For Canadians with potential dual citizenship, an official may remove your citizenship for a criminal conviction in another country, even if the other country is undemocratic or lacks the rule of law. The official may also remove your citizenship for certain serious criminal convictions in Canada, even if you have already served your sentence in Canada."
Hence, even abandoning your citizenship of birth does not help because you always have the right to re-apply for it.
