Before his arrest, Phillip addressed a group of protesters, before marching together towards a borehole site, where he crossed a police line, and was taken away by police.
"We are making a very clear public statement that we do not support the Harper and Clark governments when it comes to resources," he said before his arrest.
Phillip said that he supported Burnaby Mayor Derek Corrigan in his stand against the company's exploration on the mountain, adding that this would be the first time in Canadian history a local government bylaw would have been overruled on a land use issue.
"If push comes to shove, " Phillip said. "I'd be arrested in solidarity."
He spoke about how the future of his 15 "beautiful grandchildren" are at stake.
"I will once again be arrested. This is not the first time," he said.
"It is a matter of principle."
