Immigrant maple leaf card is not naturalized for a long time

Which country are you talking about? From Canada to China or from China to Canada?

If you have an unexpired passport, it doesn't matter if the record is blank, because if your passport has expired, the passport obtained from the China Consulate in Canada is a new blank passport. Even if you lose it, you can apply for a new passport if you report the loss. Anyway, if you go back to China, it won't be affected. The worst thing is to apply for a home visit permit without a passport!
