I have available funds for my self. But I failed to open an account with my only self as I have no SIN thus the bank advised us to open a joint bank account. Is it ok to a have a joint account ? I am working in my own country. Currently, there are no flights to my country. Also, I am worried about my younger sister as she is here alone for her studies.That is why i am trying to apply for an extend.There isn’t an exact amount. You should be able to support yourself in Canada without help from your sister and have the funds to travel home. Is there currently flights available to your destination? Unless you are retired most adults need to be at home to work or care for their family especially after 6 months. If you don’t have a lot of funds there will be concerns about you potentially working for cash or what your intentions are if you have already been away from home for 6 months.
