A. This may have happened in the past as even if you called Ontario One Call and you had a private locator, like it is required, you still may not have had complete locates. Not all hydro service providers were members of Ontario One Call and therefore you had to ensure that if the hydro provider for your site area was not a member, you had to contact them to request a locate. With the recent implementation of Bill 8 (Ontario Underground Infrastructure Notification System Act or “One Call Act”), it became mandatory for all owners of public utilities to be members of One Call.
