Leave to Open Applications
Before a pipeline or section of a pipeline can operate, companies need to apply for and be granted leave to open (LTO). The Commission must be satisfied that the pipeline is safe to use before it will grant LTO orders to a company.
Trans Mountain has applied for a series of LTO orders, and received approval for all 42 applications. The company’s LTO applications reflect pipeline spreads and facilities such as pump stations or tanks.
Trans Mountain requires LTO for its pipeline components and facilities to transport oil from near Edmonton, AB, to the tanker loading facilities at Westridge Marine Terminal in Burnaby, BC.
Below is a table with LTO applications that Trans Mountain has submitted and the status of each.
