HI! My father landed in Canada and became a permanent resident in 2019, but he returned to China in 2020 to visit my grandma who's over 90 years old. Due to the pandemic and lockdown and travel restrictions, repeated flight cancellations during 2020 to 2022, and undergoing two major surgeries(cancer related) and recovery in 2022, he was unable to return to Canada on time and is now nearing the time for residency renewal. My mother stayed in China during this period to take care of him, and she also had undergone an surgery herself in 2023, my father had to take care of my mother during that period of time, and they both lived in Canada before the pandemic and his illness, as of now, they both have fulfilled just 1 year of RO in the last 5 year rolling period. I am their only child and have two children living together in Canada, my parents provide significant help, such as driving and childcare, which greatly improves my work efficiency. I wonder if a humanitarian application might allow them to renew their residency despite not living in Canada for 2 out of the last 5 years. If the application is rejected, can they still stay to complete the required two years and then reapply? What options do we have?
