How much does relocating a gas line or hydro pole cost before a pool dig in Ottawa?

Relocating a gas line or hydro pole before a pool dig is one of those pre-construction costs that catches Ottawa homeowners off guard, and it can range from a few hundred dollars to well over $20,000 depending on what needs to move and who owns it.

Gas line relocation is handled by Enbridge Gas (the local natural gas utility serving Ottawa) or by a TSSA-licensed gas contractor working in coordination with Enbridge. If the gas service line running to your house needs to be rerouted to clear the pool excavation area, you are typically looking at $1,500 to $5,000 for a straightforward residential relocation — moving the line a few metres along the foundation or re-routing it around the planned pool footprint. If the line that needs moving is a higher-pressure distribution main rather than just your service connection, costs escalate significantly and the timeline stretches out, sometimes by several months. Enbridge controls the schedule for distribution main work, and they are not always quick. Book an assessment with them early — ideally before you finalize your pool design — so you know what you are dealing with before you have committed to a layout.

Hydro pole relocation is a different animal entirely, and it tends to be the more expensive and time-consuming of the two. Hydro Ottawa owns and controls the poles and overhead lines in most of the city, and they charge the homeowner the full cost of relocation when the move is for private benefit (i.e., your pool). A single pole relocation with associated line work typically runs $5,000 to $15,000, and if the pole carries multiple circuits or serves neighbouring properties, costs can push higher. The permitting and engineering review process through Hydro Ottawa can add weeks or months to your timeline. Some homeowners in this situation opt to underground the service instead, which is often a comparable cost but results in a cleaner finished yard.

The practical takeaway for Ottawa pool planning is this: call Ontario One Call (1-800-400-2255) before any excavation, which is legally required, and then separately contact Enbridge and Hydro Ottawa directly for formal assessments if their infrastructure appears to be in or near your planned pool area. These are not costs your pool contractor controls — they are utility company charges billed directly to you, separate from your pool installation contract. A reputable pool contractor will flag these issues during the site assessment phase and help you sequence the work properly, but the utility relationships and payments are yours to manage.

Timing matters enormously in Ottawa given the short construction season. If you are planning a pool for summer 2026, utility relocation assessments should ideally happen in fall 2025 or early winter so there are no surprises delaying your dig once the ground thaws in April or May. Delays caused by utility work are one of the most common reasons Ottawa pool projects get pushed into late summer, costing you precious weeks of swimming season.

If you are in the early planning stages and want to connect with pool contractors who can help assess your site and flag these issues before you commit to a design, the Ottawa Construction Network directory at justynrookcontracting.com/directory is a good place to start comparing local pool professionals.
