Ah hit and run...that sucks.
Like many have mentioned here, if you know who did it, then ICBC will bill the other party provided that all checks out. You shouldnt have to pay anything.
However, if you dont
know who did it, maybe get a quote from a bodyshop. Not sure of the extent of your damages but if the repairs are under $300, then may be better to just get things fixed bypassing ICBC. Otherwise, Im thinking you're gonna be paying the full deductible going through them....
Hope all works out for you.
