If you go to Canada and live in Canada for three years within five years, you can obtain immigration status and retain permanent residency (maple leaf card) ~

No , you 're going the wrong way. If you keep the maple leaf card, you will meet the requirements if you live in Canada for two years within five years. Including the time when Canadian companies are sent to work in China, it also counts as the time when they live in Canada.

It is suggested that you complete high school courses in China, then apply for junior college (university courses) in local public universities in Canada, work in Canada 1 year after graduation, and then apply for Canadian experience immigration.

If your purpose is to obtain Canadian immigration status through studying abroad, I suggest you apply for courses in public institutions and get a visa through the spp program.

After completing at least two years of junior college courses in the local area, you can get a three-year work visa after graduation, and you can get immigration status through the experience category after working for one year.

If you are interested in applying to a local public college in Toronto, such as Centennial College or seneca College, I can help you get the acceptance letter.
