Urgent ... I just immigrated to Canada and want to work in Chinese education. Do I need to obtain a foreign teacher qualification certificate? Or some other certificate?

First of all, don't take teaching Chinese in Canada as very important and difficult. Because Chinese education in Canada is an amateur education, parents want their children to learn some Chinese, mostly for about 2 hours on weekends. Of course, the effect can be imagined.

Secondly, the so-called schools in China are all run by individuals or institutions, not formal education. Of course, teachers don't need a qualification certificate. Some teachers can't pronounce correctly.

Finally, I suggest that you don't take Chinese teaching as your main job. If so, I'm afraid you can't even earn money for dinner. If you are interested, I can give you some other suggestions.
