My boyfriend's aunt's family of four is in Canada, and we both want to immigrate to Canada after we get married this year. Can we apply?

Unless a company in Canada wants to invite you two to work in the past, it is basically difficult for you to immigrate there. Not to mention immigration, it is difficult for you two to apply for an ordinary tourist visa to go to Canada because you have relatives in Canada. Now Canada has tightened its immigration application. Your conditions are not the point of reference. If you really want to immigrate, you'd better let your boyfriend's aunt make good connections there and apply for your past in the form of skilled immigration.
