FEATURE

THE

HISTORY
OF LOCATES IN ONTARIO
By Dave Wulff, General Manager, Vivax-Metrotech Canada

L

ocates have been performed for as long as utilities have been placed in the
ground; however, the process
has come a long way.
The concepts involved in performing
a locate typically include seeking out, or

creating an electromagnetic field, that
ideally surrounds a buried conductor,
and using a receiver to locate the center of the field and mark out the ground.
Early research was carried out by
Michael Faraday (22 September 1791 -
25 August 1867), an English scientist

who contributed to the study of electromagnetism and electrochemistry.
It's not widely known, but gas distribution was first introduced to "Muddy
York", as Toronto was then called, circa
the mid 1800's (prior to Confederation!).
The infrastructure was primarily located

This picture demonstrates Locators in 1910 using a crude receiver (a roof truss with wire stapled to it) which was very labour intensive. Depth
measurement would have been provided by workers with shovels. For more information please visit https://www.radiodetection.com/en/
