Buffer zone

By: Ontario One Call

Members may advise Ontario One Call of a range of distance from their actual physical plant that they would like Ontario One Call notifications in. This range is called a “Buffer Zone”. This distance can vary depending on the level of confidence of the member in the accuracy of their plant location records, and the degree of risk associated with potential damages.

To minimize the risk of under notifications, the member should ensure that the buffer zone includes adjacent roads paralleling the plant location. The buffer zone must be shown by the member on the maps provided by Ontario One Call. When the process is complete for linear plant, the map will show a corridor consisting of the buffer zone around the plant location, as opposed to a single line on the map.
