You have to show that you are personally being persecuted. It appears that this is also for your parents. H&C is also not a way to circumvent the PGP process. Both H&C and asylum application have significant longterm consequences especially asylum claims. If your parents are visiting and are denied H&C they may no longer be able to easily visit Canada. If they claim asylum and are denied they will face difficulty traveling to many countries.What do you mean I am not eligible?they are not caring who have participated and who havent,they are not even sparing small kids who were playing in their home at that time,just killing people randomly,just the fact that your political opinion doesnt match with their political opinion is sufficient for you to being killed….
