The following is a worldwide list of pipeline accidents.
Belgium 2004: A major natural gas pipeline exploded in Ghislenghien, Belgium near Ath ( southwest of Brussels), killing 24 people and leaving 122 wounded, some critically on July 30, 2004.
Canada A TransCanada pipeline ruptured and exploded in North Bay, Ontario, in the early 1960s and again in 1978. 1958: The Slater Street explosion: A massive explosion rocked the Centertown core of Ottawa at 8:17 am on Saturday, October 25, 1958. As an Ottawa Citizen reporter later described, the scene looked “just like a bombed area in wartime London.” The explosion occurred at the Addressograph Multigraph building at 248 Slater Street when natural gas seeped into an unused manufactured gas pipe system and into the building. A chemical reaction occurred. When a janitor turned on a light switch, the gas in the air exploded. Debris caused major traffic problems and 40 people were injured from flying glass fragments. 60 off-duty police and RCMP officers were called in to help police evacuate the area. William J. Anderson, the janitor at the Addressograph Multigraph building, died several days later from injuries sustained in the blast. Prime Minister John Diefenbaker came to the site to view the destruction. Over 25 businesses were closed indefinitely. Prince Philip arrived in Ottawa on October 31 to view the explosion site and question officials. Overall, the entire incident cost the government two million dollars in damages. 1962: An explosion on a gas pipeline occurred on a lateral line on January 17, about northwest of Edson, Alberta. 8 people were killed. 1965: An explosion from a gas line destroyed several apartments in the LaSalle Heights Disaster in LaSalle, Quebec killing 28 people, the worst pipeline disaster in Canadian history. 1965: On October 12, an explosion and fire involved the Albert Gas Trunk Line LTD., near Sundre, Alberta, killing 2 pipeline workers. 1969: On October 25, a faulty pipe exploded in a gas line beneath Malton, Ontario.

Approximately of sour natural gas was released and ignited. 1997: On December 2, a rupture occurred at an area of external corrosion on the TransCanada PipeLines Limited outside diameter Line 100–3 at main line valve 5-3 + , near Cabri, Saskatchewan. Approximately of natural gas was released as a result of the rupture. The gas ignited immediately, resulting in damage to the surrounding soil and vegetation. The main fire self-extinguished within 20 minutes of the line break. 1999: On May 20, Line 3 on the Enbridge Pipelines Inc. (Enbridge) pipeline system ruptured, releasing of Cold Lake heavy crude oil, east of Regina, Saskatchewan. Approximately of farmland was affected by crude oil. 2000: On December 28, a release of natural gas resulted in an explosion that destroyed the electrical and services building, heavily damaged the compressor building, and damaged the remaining buildings at the East Hereford compressor station, approximately SE of Magog, Quebec. Before the occurrence, the station had been shut down due to an unintentional manual initiation of the station's emergency shutdown system. Following the emergency shutdown of the compressor station, a maintenance person was sent to the station to reinitiate the electric motor-driven compressor unit. During the day, after repeatedly trying to get the station into the ready state mode, to return the station to normal pipeline operations, an explosion occurred. The on-site maintenance person was seriously injured. 2001: On January 17, a rupture occurred on the Enbridge Pipelines Inc. outside diameter Line 3/4 at Mile Post 109.42, downstream of the Hardisty pump station near Hardisty, Alberta. The rupture occurred in a permanent slough that was fed by an underground spring. Although the line was shut down at the control centre in Edmonton, Alberta, within minutes of the rupture, the exact location of the rupture was not found until after 13 hours. Approximately of crude oil was released and contained within a section. As of 1 May 2001, of crude oil had been recovered. 2001: On September 29, a rupture occurred on the Enbridge Pipelines Inc. outside diameter Line 10 at Mile Post 1885.64, near Binbrook, Ontario. Line 10 transports crude oil from Westover, Ontario, to Buffalo, New York, United States. The rupture occurred in an agricultural field planted with soybeans. Within eight minutes of the rupture, the control center operator in Edmonton, Alberta, shut the line down and began to sectionalize it. Remedial action response teams contained the spill to two general areas, a natural swale running perpendicular to the pipeline and the pipeline trench. Approximately of crude oil were released, affecting a section of land. 2002: On April 14, a rupture occurred on the -diameter natural gas transmission pipeline, at a zone of near-neutral (low) pH stress corrosion cracking, on Line 100-3 of the TransCanada PipeLines, at main-line valve 31-3 + , approximately from the village of Brookdale, Manitoba. Following the rupture, the sweet natural gas ignited. With the automatic closure of main-line valves upstream and downstream of the rupture site, the fire self-extinguished at 2:30AM, on 15 April 2002. There were no injuries. As a precautionary measure, approximately 100 people were evacuated from the occurrence area within a radius, including the village of Brookdale, for a period of one day. 2002: A refined product pipeline rupture near Saint-Clet, Quebec, on December 7, from Trans Northern Pipelines Inc. diameter mainline kilometer post 63.57, estimated of low sulphur diesel released to area and drainage systems. 2003: A backhoe punctured a pipeline in Etobicoke, Ontario, the resulting explosion killed 7 people. 2005: On July 15, an employee of Terasen Pipelines (Trans Mountain) Inc. discovered crude oil on the pipeline right-of-way, on the north side of Ward Road, Abbotsford, British Columbia. Before the discovery, the company had been delivering crude oil out of the Sumas Tank Farm, when it received odor complaints from local residents. Approximately of crude oil was released into the surrounding area and made its way into Kilgard Creek.
