Opposition is mounting in Winnipeg to an oil pipeline set to run through Manitoba.

The Energy East pipeline will convert natural gas lines to crude to ship oil from the west to eastern refineries.

A coalition of environmentalists opposed to the project gathered in Winnipeg, calling on the National Energy Board to study the impact the pipeline will have on climate change.

The City of Winnipeg will spend $1 million to hire experts to review the impact and oil spill could have on its water supply and landfill.

The city is applying for intervener status at next year’s hearings at the NEB.

Officials with the Energy East project said the pipeline would not pose and danger to the water supply. It said it has the technology to monitor the existing pipes and prevent a spill from happening.

TransCanada Pipeline, the corporation behind the project, spent Monday in Winnipeg meeting with First Nations leaders in downtown Winnipeg. Some First Nations advocates protested outside of the meeting, accusing their leaders of selling out to the oil company.
