What you need to know for Canadian crossing applications

TransCanada is committed to the safety of everyone living or working near our pipelines and associated facilities. Certain activities can pose a risk to a pipeline and those around it.

To ensure TransCanada pipelines and facilities remain operating safely, written consent from TransCanada must be obtained in the following situations:

  • Constructing or installing a facility across, on, along or under a TransCanada pipeline right-of-way
  • Conducting ground disturbance (excavation or digging) on or within the prescribed area (30 meters from the centreline the pipeline)
  • Driving a vehicle, mobile equipment or machinery across a TransCanada pipeline right-of-way outside the travelled portion of a highway or public road
  • Using any explosives within 300 meters of TransCanada’s pipeline right-of-way

Application and Consent process

1. Application:

When planning, and before any of the work or activities listed above can begin, a request for consent must be submitted to TransCanada.

2. Application assessment and consent:

3. Work or activity:

Once consent has been granted, the party completing the work or activity must contact the local one-call notification centre at least three business days before beginning the work.
