Is there any good way for chefs to immigrate to Canada?

It's best to find a reputable immigration agent in Canada and give you an immigration assessment first. If you don't need to find an employer abroad, you can apply for immigration and do DIY. If you have to find an employer, you can find an immigration agent in Canada to help you do AEO skilled migration, but the cost is relatively high.

The Canadian government has not certified any immigration agency in China, and domestic immigration agencies are generally handled by Canadian immigration agencies. In Canada, immigration agents have to pass the exam to qualify.
