Canadian immigrants returned to live in China.

After becoming a Canadian citizen, you need a visa to return to China. How long it takes to sign depends on how long the China Embassy gives you. If you have a maple leaf card, you can return to Canada at any time, but if you want to keep the maple leaf card, you must meet the condition of living for two years in any five years.

In addition, China does not recognize dual citizenship. Therefore, it is better for you to apply for a visa at the China Embassy with a Canadian passport when you return home.
