I,m relocating to canada,i have a poor credit rating,although i wont need a mortgage,will it affect my application for residency or hinder me getting a bank account.
Answer
I had a friend who moved to canada, he was elderly and retired, he had to basically show that he would not need state support for 10 years, he had the money from his savings and sale of house, but he still needed his daughter and son in law to be guarantors to his credit worthiness.
