A Canada visa is a stamp on your passport which allows you to enter the country of Canada. It is a permission for you to travel to the country and legally be able to stay either temporarily or permanently. Getting a visa to Canada means that the Canadian Consulate or Embassy in your home country decided that you are eligible and fulfill the requirements for entry. However, once you are at the Canadian border and customs, it is up to the officers at the border to evaluate whether you are fit to enter. If you answer the Canadian Border Services Officer (BSO) questions honestly and correctly, they will allow you to enter. Otherwise, if they suspect that you are not eligible to enter, they can deny you and ask you to go back to your home country even if you have a Canada visa
