Thank you Scylla. In fact I have all the medical evidence for my mother including her death certificate. I could not attend the 2016 interview because my PR card expired in May 2015, so could not re-enter Canada, after my mother's death. Do you have an idea of the chances for my PR renewal in the actual circumstances.
Would be thankful, if the current status of your case is posted with sequence of events as this can be helpful and useful for others having similar situations.
Thanks,
