I have applied for a Canadian Visitor Visa for myself to visit my family. My son aged 5 years is going to accompany me but his father is not coming along. So do I need to apply for a visitor visa for my son as well? I am confused because this page says he needs just passport, birth certificate and authorization letter from his father. (https://www.canada.ca/en/immigratio...-canada/minor-children-travelling-canada.html). Please advise. Thanks
