New Canadian immigrants enter the customs at Toronto airport. How should I go through the formalities?

It seems that you need to fill out an immigration application or something when you get off the plane and go to customs. Do you have any cigarettes, alcohol, weapons or guns? When you are in line, if you immigrate, you should bring immigration documents with you at any immigration gate. Then you can speak Chinese crazily, and she will take you back to your Chinese-speaking immigration. All airports in Canada have Chinese signs. Follow them.
