Canadian Airport Immigration Landing documents are not consistent with citizenship and not the only path to citizenship. It's a landing document that confirms your status at the time of landing. It does not confer any right to benefits. Do you have citizenship? Do you have permanent residence? The evidence is recorded in the system. If you lost your landing document but have your passport that says you are a citizen, you have all you need. It's not the landing document. They are not requested or required for any government business. No one has ever asked for a copy and to do so is criminal mischief; illegal.
