What are the differences in immigration policies for international students in different provinces of Canada? Why does everyone say it's good to immigrate to Ontario?

If you want to immigrate after studying abroad, generally speaking, Canada's policy is good, and those who are able to contribute to Canada are good immigrants. However, Saskatchewan and Alberta, which you mentioned, are vast in territory and rich in resources, but few in people, so these two provinces are more willing to leave outstanding talents and create value for their own provinces. Therefore, these two provinces are better than Quebec, Ottawa, the capital, and Toronto, a densely populated metropolis.

You can trust me privately if you have any questions. If you are satisfied, please accept it. Thank you.
