How to immigrate the whole family to Canada

The whole family immigrated to Canada:

1 For example, my mother came to Canada to be a nurse and take care of the elderly. After two years, she can apply for immigration and then reunite with her with her husband and children.

2, children go to Canada to study first, work for one year after graduation, apply for Canada to experience immigration, and then bring their parents here after the children become Canadian citizens. This is not recommended and takes a long time;

3. The last one is investment immigration. If you are allowed to work full-time, 1 the whole family can immigrate to Canada in one and a half to two years.
