Ontario One Call will determine the status of each member for each excavator locate request, i.e. whether the member will receive a notification or not. Ontario One Call will inform the excavator as to which members will be notified. Where the member has signed the appropriate Selective Sending Addendum (see Selective Sending for more information), Ontario One Call will provide an “All Clear” on behalf of members who do not need to complete a locate for a particular excavator locate request. Ontario One Call will also inform the excavator of their responsibility to contact non-members directly.
