“The project, in combination with other existing, approved, and planned projects, is likely to result in significant adverse cumulative environmental effects to wetlands, old-growth forests, wetland- and old growth-reliant species at risk, fisher, Canada lynx, woodland caribou, the Ronald Lake bison herd, and biodiversity,” the joint panel report concluded.

“The panel also recognizes that if the project is approved and constructed, it may make it more difficult to achieve Canada’s targets and commitments under the Paris Accord.”

The bison herd is the last free roaming herd in Canada.

The Frontier project would be twice the size of Vancouver, pumping out 260,000 more barrels of bitumen a day. But it can only be built if Trans Mountain is there to carry away the oil.
