I don't think it will be a big problem. (As this is for address history, it wont affect the presence calculator or anything.)I left USA on Oct 30,2019 and reached India on Nov 1,2019 since its approx 24 hours air travel. Due to this, there is a gap in my address history [Missing Oct 31,2019]. How can I fix the error when applying online ? Make date left USA to Oct 31 ? and then explain it in LOE ? Any gaps = application returned so I am not sure what else can be done. :|
May be use Oct 31 as the date you arrived in India as Canada have information sharing with USA.
