Hello everyone , My parents want to apply for Canada Visitor Visa - under Temporary Residence Category ( less than 6 months). My aunt (mother's sister) and her husband are Canadian citizen. My father is the primary applicant and my mother is secondary applicant. Now in the primary applicant section they are asking to upload the relationship proof document. My question is since my father is the primary applicant how he can show that his relative residing in Canada is his sister-in-law? If i upload marriage certificate of my parents and birth certificate of my mother and my aunt will suffice the purpose or is there any other way ? I would be glad if somebody can guide me on this.
