The whole basis of a H&C app is that it would be a danger or present unreasonable hardship should the applicant leave Canada back to their home country. So her leaving Canada voluntarily during the process shows H&C may not apply to her, and app would have a significantly higher chance to be rejected. So she should plan to stay in Canada for duration of process.
You do not have an H&C case. Being unable to meet the income requirement is not grounds for H&C. His parents are still relatively young and they are not alone, as they are together, so you have no grounds there either.
My mother is 84 in good health condition,widow, with no relatives back home. All her siblings in home country have passed away. She lives for more than a year now with me (I am her onlychild) and my family. I have been in Canada for 2 years with PR status and my husband and my son are Canadians. Do you believe we have the grounds to go with H & C case?
Yes definitely grounds for a H&C app to be successful. Of course no guarantees, it will come down to discretion of visa officer reviewing her case.
My only concern would be where were you living previously? Were you living with or close to her 2 years ago?
She was living with my father in her home country. After my father passed away she visited us here in Canada and have extended her visa. Back home we were living in the some town but not together.
My only concern is that you only recently moved away from your parents to go Canada knowing your parents were 82+ and had no family around. You didn't seem to have made any plans knowing that your parents (now mother) would need help.
