What happens if you reply through web form (within 5 dats )telling them that parents are coming back in 10 days to Canada ? Willl they accept it and ask again to prove that parents have arrived in 10 days ? Or will parents now not be able to come back to Canada on their supervisa? ThanksYou need to tell them in 5 days through webform that your parents are in canada. Otherwise you need to submit passport overseas
