I immigrated to Canada. What about social security in China?

During the period when you hold the Maple Leaf Card, your household registration does not need to be cancelled, that is, you are still a citizen of China, which has no influence on your social security. But if you want to be naturalized in Canada, that's another matter. Dual nationality is not allowed in our country. As long as you are naturalized in Canada, you have the obligation to declare naturalization to the Chinese Consulate and cancel your China account. Once your household registration in China is cancelled, your social security contribution will be invalid. So when you immigrate to Canada and hold a maple leaf card, you can enjoy the rights and interests of Canadian residents according to law, that is, milk money and medical insurance, and your social security is still valid. Naturalization in Canada needs to measure the significance of domestic social security to you.
