Am I eligible to purchase Top-up insurance to extend my coverage if I am unable to return home from the affected region? 

Yes, you are eligible to purchase a Top-up policy as long as your current travel coverage is still active and you have not exceeded the total number of days. Please note that if an active “avoid all non-essential travel” or “avoid all travel” Government of Canada travel advisory is issued, you are advised to return home as soon as possible.
