I am Canadian citizen, my parents are PR card holders from India. Their PR card is expiring august 30, 24, they have been in Canada just once for 85 days from august 2019to October 2019. They are planning to come to Canada in 2023, question how can they meet residency obligation of 730 days? What are their options if PR card expires, and they have not met the residency obligation? Can they still live in Canada once PR card expires? Will my being Canadian citizen help?
