Through Access to Information requests CBC News has obtained data showing, nationally, the number of leaks, fires or so called "incidents" involving pipelines has doubled since 2000.
From the six Toronto-area pipelines, there have been 36 incidents involving damage, leaks or fires since 2000, CBC news has learned.
Most were minor, but others were more serious. In 2010, a Trans Northern pipeline leaked 90 thousand litres of gas into Oakville's Bronte Creek before it was noticed. The clean up continues to this day.
Many of the pipelines in the GTA are decades old. Trans Northern's, for instance, was built in 1952. They are routinely inspected, still an estimated 30 percent of leaks aren't detected by pipeline owners. Instead the public are the ones reporting them.
