Activists say hundreds of protesters voiced their opposition to Kinder Morgan's Trans Mountain pipeline project at a rally in Burnaby on Saturday.

The protest was held outside National Energy Board hearings on the project, which aims to triple the capacity of the Alberta-to-B.C. pipeline.

Residents, First Nations and environmentalists called on Prime Minister Justin Trudeau to keep his campaign promise and overhaul the federal review process.

Opponents say the review has ignored climate change, failed to pursue indigenous consent, flouted proper procedures and shut hundreds of people from the process.
