Enbridge Inc. says it's found the solution to an exposed oil pipeline in a Toronto park, after an environmentalist told CBC News he was worried it could be site of a spill.

The pipe in question runs through Rouge Park, a large wilderness area in the city's northeast. It's part of a line that crosses the south of the province, taking crude oil from Quebec City to a refinery in Sarnia, Ont.

The pipe is part of a line that was built in the mid 1970s, but in 2009 the river bank started to erode, shifting the water's edge and leaving the pipe exposed.

Enbridge, which has had highly-publicized spills in Wisconsin and Michigan, had responded to the problem by placing concrete blocks around the pipe as temporary protection.

That didn't sit well with Adam Scott of the organization Environmental Defence, who warned Thursday that a spill there would be serious trouble for threatened and endangered species in the area and could easily flow to Lake Ontario.

Later in the day, Enbridge spokesman Todd Nogier said the company has developed a cover that satisfies the regional conservation authority that oversees the park.

"We've been working with the authority to come up with a solution … something that blends in a little bit with the surroundings and something that they felt was not obtrusive," he said.

Nogier said work will begin soon and they hope to have a cover in place in a couple of months.

Warren Mabee, an expert on energy and environmental policy at Queen's University, said the chance of a spill in the park was always low, but it's good that Enbridge is being vigilant.

"It's probably a good time to do some inspections and its a good time for Enbridge to be very open about any issues that they find."

The Calgary-based company is at the centre of a dispute between Alberta and B.C. over their proposed Northern Gateway pipeline, which would carry heavy oil from Alberta across B.C. to a port for shipment to Asia.
