Ask a question

We want to keep Canadians informed about pipelines, so if you have any questions, please fill in the form below and we’ll respond as soon as possible.

What methods are used to ensure the pipeline will not rupture or leak over time? – Lynn M.
Why won’t companies post all their spills and accidents? – Dave
What do you mean by a 99.9% ‘safety record’ — this seems to me like you’re just playing with numbers. If your goal is zero incidents, then the only reasonable response would seem to be to reduce the number of pipelines not expand them. – Peter I.
How often are pipes replaced? Are there regulations stating replacement intervals depending on type of pipe used? Or are they only replaced if anomalies are found? If so, how often are pipelines inspected according to both provincial and federal regulations? – Erynn (Lloydminster, AB)
What happens when a pipeline bursts? – Lena
How many pipelines are there in the USA and Canada and how many are being built right now? Also how many pipelines are being planned to be built? – Cora-Beth
What pipeline projects are underway and starting soon in Canada? – Frank
How are you making sure that your pipelines have not been sabotaged by eco-terrorists? – George R.
How closely are pipelines monitored? Is there daily visual or aerial inspections of all pipeline routes? Are there pressure and flow meters along all lines hooked up to valves that can automatically close if there is a sudden drop in pressure or flow from the readings further up the lines? – Graham
“Why do you believe that you are safe from the serious damage that has been done by hackers?” – George M. “Who and how will this pipeline be protected from a possible terrorist attack?” – Tony R. (Cambridge, Ont.)
“We must build anew and replace all of the aging infrastructure so it does not leak.” – Bruce F. (London, Ont.)
“Is this pipeline being built with swaying joints to prevent breakage should an earthquake occur?” – Tony R. (Cambridge, Ont.)
“How are you 100 percent positive there will never be a leak or burst?” – Nadine M.
“What kind of safety measures are put in place close to rivers? Do you have an emergency plan in place?” – Bert B. (Bella Bella, B.C.)
“I would like to know how we can replenish the earth and restore our relationship.” – James D. (Niagara Falls, Ont.)
“When will you take the long term view and learn from progressive countries that are turning to renewable energy sources?” – George M.
“How can we be assured that a spill from a dilbit pipeline won’t take over five years to clean up?” – Scott R. (Whistler, B.C.)
“Say you have a breach in a length of pipeline somewhere in the heart of the Rockies, and for argument’s sake, let’s say the breach is in the most remote area of the pipeline route. How long until the breach is detected, how long until the oil flow is stopped due to a pressure drop and the activation of the safety valves, and how long until it can be repaired?” – Alex O. (Burnaby, B.C.)
“Two of the issues facing pipelines are ground movement and corrosion (from both the inside and outside). Two questions: How are you going to effectively monitor for these issues? What are your contingency plans for when the worst-case happens?” – Robert B.
