MNT: Port Moody / Burrard Inlet Crossing
Through Port Moody the new line would be added to within our existing right-of-way in and adjacent to Belcarra Regional Park.
Within the right-of-way, existing lines will be consolidated onto fewer, taller poles. The location of these poles will be the subject of further study.
In Port Moody, our preliminary design includes the proposed power line built along approximately 5 km of our existing right-of-way:
- Between Coquitlam and Anmore, there is a short 760 m section where the line would be supported by two steel H-frame structures, totaling five poles.
- West of Anmore the line would re-enter Port Moody, staying within our rights-of-way in and adjacent to Belcarra Regional Park, and passing through a short section of Admiralty Point Park before it spans Burrard Inlet. For this area, we will be consolidating existing lines with the new power line onto fewer, taller poles. Our current design lets us reduce the total number of existing structures by almost half; 78 wooden structures would be replaced with approximately 28 taller, steel structures. We still need to design the towers and determine their exact placement within the right-of-way.
Approximately two kilometres of the existing right-of-way is within Belcarra Regional Park and we aim to minimize impacts by:
- Maximizing vegetation retention and minimizing disturbance in riparian areas;
- Planning work outside of bird nesting window, where possible;
- Retaining the maximum amount of healthy understory trees in the right-of-way;
- Where we have to remove or modify hazard trees outside of the right-of-way, modifying some into standing wildlife trees and coarse woody debris; and,
- Using existing access.

Our preferred route:
- Uses our existing right-of-way for new 230kV poles, eliminating the need for a third transmission crossing of the inlet.
- Considers input from First Nations, the cities of Burnaby and Port Moody, Metro Vancouver and the federal government.
- Uses our existing property on the south side of Burrard Inlet to transition the line from overhead transmission line to underground transmission cable.
Frequently asked questions
As this is an existing right-of-way, any additional tree removal for this project would be to ensure that there is appropriate clearing for the safety and security of the additional line. This would include any danger or high-risk trees. Studies are underway to determine how many trees will need to be removed in this area.
See the rights-of-way and corridors page for more information.
Through the Port Moody (west) right-of-way, the new towers will be a single steel monopole that will support four power lines – the three existing 69 kV lines with the additional 230 kV line that is part of this project. Engineering studies are underway in this area to help inform the design of these towers.
The design of the structures that will be used for the crossing at Burrard Inlet are being looked at and not finalized yet.
We've completed some field studies along the right-of-way within Belcarra Regional Park in 2015 and 2016 to identify fisheries, vegetation, wildlife, amphibians and archaeological requirements to inform the design, tree removal and access strategies for the project. Additional studies are planned in 2017 and 2018 as design advances.
