Why has the smallest Canadian province become the new favorite of China immigrants?

Simply put, it is difficult to immigrate, and the language of other countries is also a problem, belonging to a small language country. There are also livelihood issues after going there. All these should be taken into account. Canada is an immigrant country, and its immigration policy is different from other European countries. As far as I know, it is not as difficult to obtain French citizenship as it is to obtain Canadian citizenship.
