Some protesters are trying to stall the Trans Mountain pipeline expansion by making sure a few dozen trees aren't chopped down.
Kinder Morgan has permission to remove trees in the area of Burnaby Mountain in order to dig a tunnel between its Burnaby and Westridge Marine terminals.
The trees must be cut down by March 26, after which protections kick in for migratory birds.
David Mivasair of an anti-pipeline group called the Justin Trudeau Brigade said delaying the cutting down of the trees for three weeks could lead to months of delays for the tunnel digging.
