Five people were arrested on Saturday following a protest in the waters near Kinder Morgan Canada Ltd.'s Westridge Marine terminal in Burnaby B.C.

More than 60 boats linked together in front of the tanker route which runs from the terminal.

First Nations along with environmentalists, local politicians and residents are continuing their protest of the company's expansion of its Trans Mountain pipeline, which runs from Edmonton to Burnaby.

The federal government has approved the $7.4 billion project.

The proposed expansion of the Trans Mountain pipeline from Alberta would nearly triple its capacity to 890,000 barrels per day and significantly increase crude tanker traffic off the West Coast.

Still environmental and aboriginal groups have filed for a judicial review that could overturn the project's federal approval.

The concern from protesters is the threat of an oil spill in Burrard Inlet.

"It's a risk that we cannot take," said Rueben George with the Tsleil Waututh Nation at the protest on Saturday, one of several he has attended and spoken at.

On Thursday Kinder Morgan appealed to the National Energy Board after being continually stonewalled by the City of Burnaby in securing local construction permits for the expansion.

RCMP said the five people arrested as part of the protest on Saturday were released, but will have to appear in court at a later date.
