Valued Customers and Partners,

USL-1 Underground Service Locators is monitoring the status of the novel coronavirus. We want to assure our customers and partners that we are currently operating and continuing to provide service throughout our group, while taking all possible measures to protect our employees, customers and the public.

We are following the updates and protocols posted from the Ottawa Public Health, Government of Canada Health and Safety guidelines, WHO, and will take additional measures as they arise.  Hygiene and cleaning standards have been increased for equipment, vehicles and workspaces. Our top priority is the health of our employees and the public.

As of today:

We maintain fully operational

  • Office staff are now working from home
  • Our field staff are customer site, when safe to do so.

To protect the health and well-being of our employees and customers we are implementing the following changes:

  • Avoid in person contacts when possible
  • Enhanced cleaning protocols at the offices, job sites and vehicles will be performed
  • Any employee who travelled abroad including to the United States is mandated to self-isolate for 14 days

As we continue operating under these circumstances, rest assured that The Underground Service Locators and all our employees will continue offering the highest and safest level of service.

Feel free to contact us with any question through our standard channels or at
