Call Before You Dig
CEPA is concerned with the safety of homeowners, contractors, pipeline employees and communities. Use extreme caution when undertaking any construction or excavation near pipelines, and always call before you dig.
One Call to Ensure Safety
Most Canadian provinces have a call-before-you-dig program or one-call system for those planning any construction or excavation nearby pipelines.
Dial the toll-free one-call number in your province or contact your local pipeline company before starting any digging or other work that may result in contact with underground pipelines.
These call systems are there for anyone who plans on disturbing the ground near pipelines – the call operators will help locate buried pipeline and facilities prior to any digging, usually within 48 to 72 hours of making the call.
The one-call centre will notify all owners and operators of buried utilities, including natural gas distributors so they can mark their facilities with spray paint or flags to avoid any damage to pipelines and risk to public safety.
