In a statement, police spokesperson Debbie McGreal-Dinning said the protesters were "arrested without incident" and told CBC News in Hamilton earlier in the morning that some people were allowed to leave on their own.
Police charged 13 protesters, men and women ranging in age from 19 to 25, with trespassing. One man, a 51-year-old of no fixed address, was charged with breaking and entering with intent to commit mischief. Four others face mischief charges.
McGreal-Dinning said those arrested were from communities across southern Ontario, including Hamilton, Guelph, Toronto, Bowmanville, Brampton and St. Catharines.
Graham White, a spokesperson for Enbridge said the company gave protesters "ample time" to leave the site after an injunction was issued on Tuesday. "It was done in a quick, efficient and peaceful process," he said.
White added that Enbridge still has police on site and are doing a safety assessment. He added that initially it appears the protesters did no significant damage to the site.
Police said the roads around the hamlet of Westover, where the pumping station is located, are now open.
Candace Gayle, one of the protesters who was allowed to leave the site, said that police moved in at about 7 a.m. Wednesday morning "maybe a little earlier."
"They're taking people from the back [area of the site]. People are concerned they [Hamilton police] will be rough," Gayle said. She added that she didn't think that anyone had been hurt.
"They had told the police liaisons they would give people a chance to leave," Gayle said. "They didn't. They started arresting people who wanted to leave. That was surprising because of what we had been told by police."
McGreal-Dinning said that protesters on site were allowed to leave Tuesday after the injunction calling for their removal had been received.
'It was all really fast'
Freelance journalist Tim Groves was with the group overnight and woke up to a commotion just before 7 a.m.
"It was all really fast, then I just started packing up my bags and almost immediately the police were there, and the first thing I saw was them handcuffing people."
He said police gave some the option to leave and he thought a dozen people had been arrested.
"About 20 minutes after the police cars got here, a whole bunch of machinery came, starting with a back hoe and then trucks, many of them with Enbridge logos on them."
Westover resident Joan Gerritsen welcomed the police intervention, and what she hoped is the end of the protest.
"We're glad that they're taking the protesters away. It's been rather busy around here, we're used to having a nice quiet little hamlet with a lot less traffic. We hope to have our peace and quiet back again and have Enbridge continue their work."
Enbridge obtained a court injunction around 8:15 a.m. Tuesday morning for the protesters to leave. But four remained and formed a blockade, said David Prychitka of Hamilton, a spokesperson for the protesters.
“Three of them have encased themselves in a makeshift structure that is heavily chained to the facility fence,” Prychitka said during a noon hour press conference at the site on Tuesday. “These individuals will stay in place as long as they can with the intention of stopping further construction on the Line 9 pipeline.”
Prychitka read a statement from Trish Mills, one of the protesters in the blockade.
“This is not Enbridge's land to order us off of. It is stolen,” said the statement, referencing the camp's First Nations partners. “Even if it wasn't, this company and this industry exploit and destroy land. It is our responsibility to stop this exploitation.”
Protesters allege intimidation
Protester Elysia Petrone said members of her group experienced "intimidation" from a small number of Westover residents during the occupation.
"One farmer came out with his big spray machine and sprayed pesticides right on a field beside where the protesters were sitting. It's a huge intimidation factor."
She added there had been trucks "waiting in the parking lot, following protesters and shining their high beams on them."
Petrone said some area residents were polite and helpful to her group, including one who apologized on behalf of the community for how the protesters had been treated.
"[After the pesticide incident], a neighbour came over and said, 'Sorry for our community member and make sure to wash your hands and your [bottle] of water, and wash your face."
Link to the oilsands
The pipeline from Sarnia to Montreal is divided into two sections — Line 9A and Line 9B. The National Energy Board has already approved the flow reversal of Line 9A, which runs from Sarnia to Westover. It will hold public hearings on the second leg of the project in the fall.
Line 9 crosses several major rivers that drain into Lake Ontario and the St. Lawrence River, as well as Spencer Creek, Hamilton's largest watershed.
Opponents say the pipeline will carry diluted bitumen from Alberta's oil sands, which is heavier and puts the line at greater risk of a rupture.
Petrone said the protests have helped "make more people aware of the concerns and risks surrounding this pipeline."Suggest a correction
