A group of protesters is interrupting work at an Enbridge pipeline site in north Toronto.

The blockade at Dufferin Street and Finch Avenue West is the latest in a series of actions to protest against the company's controversial Line 9 project.

A spokesman for the group, dubbed the Community Response Unit for Decontaminating our Environment, says the protesters are attempting to stop the project and stand in solidarity with previous demonstrations.

Enbridge plans to reverse the flow and increase the capacity of Line 9, which shuttles oil between Sarnia, Ont., and Montreal.

Critics argue the pipeline puts the environment at risk and there has been little consultation with aboriginal communities.

Police say the demonstration is peaceful and there are officers on scene.

Yesterday, five protesters were arrested at an ongoing blockade site in Innerkip, Ont., near Woodstock.
