CALGARY, Alberta, Sept 14 (Reuters) - A pipeline on TransCanada Corp's (TRP.TO) natural gas mainline exploded in northern Ontario on the weekend, but the incident caused little damage and had no impact on gas flows, a company spokesman said on Monday.
The blast occurred at midday Saturday on a section of line between North Bay and Timmins, Ontario. There were no injuries and only slight damage to a house, TransCanada's James Millar said.
The mainline, which has a capacity of about 7 billion cubic feet a day, is made up of three adjacent pipelines in that area. The damaged section was shut down within about 15 minutes and crews were able to reroute all the gas into the two undamaged lines, he said.
"The one that was damaged is being analyzed right now to find out the cause, and when we have an incident like this the National Energy Board and National Transportation Safety Board are called in, so they are on site," Millar said. (Reporting by Jeffrey Jones; editing by Rob Wilson)
