The Pipeline on the Title
Two pipes, one corridor. The original line dates from the 1950s; the expansion built a second, larger line beside it and entered commercial service in May 2024. In the same corridor near the Salmon River, Trans Mountain told the Canada Energy Regulator in 2024 that it would replace about 360 metres of the original line with heavy-walled pipe to mitigate a potential seismic hazard at that spot, with construction anticipated to begin in the second quarter of 2025. None of that is a reason to avoid the neighbourhood; it is a reason to know exactly where the corridor runs relative to the lot you are buying, because the rules below attach to distance from the pipe, not to the lot line.
What the right-of-way is. A statutory right of way is a registered charge on the title that gives the company the right to have its pipe in the ground and to reach it. It shows in the charges section of the title search, in whatever corporate name the company carried when it was registered, and it runs with the land: you buy it with the lot, and you sell it with the lot. Your lawyer or notary reads the registered document for its width and its terms; the plan attached to it is the drawing that tells you which part of the yard is inside the strip. The company keeps a right of access for inspection and maintenance, and the strip is kept clear of buildings and deep-rooted trees for that reason. Fences, lawns and gardens are the ordinary condition of a right-of-way in a suburb, and most of Walnut Grove's crossings look like any other back yard.
The 30-metre rule that reaches past the strip. This is the part owners miss. Under the Canada Energy Regulator's damage prevention regulations there is a prescribed area extending 30 metres outward on both sides from the centreline of the pipe, which is far wider than the registered strip. Inside that area, any activity that digs 30 centimetres or deeper needs the pipeline company's written consent, and so does cultivation to a depth of 45 centimetres or more. Within the right-of-way itself, building anything, and driving vehicles or mobile equipment off a roadway over the pipeline, both need consent. Before any digging near the corridor the rule is to contact BC 1 Call, the Click Before You Dig service, so the pipe can be located; the regulator's guidance is to make the request at least three working days before you plan to dig, and to plan ahead because locating and consent take time. A pool, a detached garage, a retaining wall, a septic replacement, a deck on concrete piers, a row of trees with a mechanical auger: each is a permission, not a weekend.
What it does to the plan for the lot. Read the registered plan against your own drawing before you fall in love with a layout. The strip itself takes the pool and the shop off the table where it runs; the 30-metre band takes the spontaneity out of everything else, though not the possibility. Consent is routinely given for work that does not threaten the pipe, with the company's conditions on depth, method and supervision. The practical cost is time and the occasional site visit, and the practical benefit is a strip of open ground the neighbours cannot build on either. A lot the corridor crosses at the back fence is a different proposition from one it crosses under the driveway; the plan tells you which you are buying.
Disclosure and the sale. A registered charge is on the title for any buyer's lawyer to read, so there is nothing to hide and no reason to. Sellers do well to have the right-of-way plan and any consents for past work (the pool, the shop) in the disclosure package, because a buyer who finds the charge on the title search and nothing in the package assumes the worst. Buyers do well to ask the one question that matters: was anything built inside the strip or the prescribed area, and was it consented? An unconsented structure over a federally regulated pipeline is a problem that arrives with the company's next inspection, and it arrives addressed to the current owner.
What we can and cannot say about value. The board publishes no figure for the effect of a pipeline right-of-way on a Langley sale price, and we will not invent one. What the September 2026 report does say is that Walnut Grove as a whole is the tightest detached market in the township, 3.6 months of supply, a median 21 days to sell at 97.6 percent of asking, and the mildest benchmark fall in Langley over the year at 4.9 percent; the corridor has run through it for the whole of that record. The right-of-way is a fact to be priced lot by lot, on how much of the usable yard it takes and what the owner wanted to do there, not a discount to be applied to a neighbourhood.
The neighbourhood's own list. Trans Mountain and the Township signed a community benefit agreement under which the company contributes $1.4 million to the Township. The Township's stated satisfaction, once its route concerns were addressed, covered groundwater management for the vulnerable aquifers, construction methods on its roads, and reclamation of its parks and environmentally sensitive areas. Restoration of the construction footprint through Langley continued after the line went into service. If the lot you are considering was on the construction spread, ask what was restored and when; the answer is usually in the seller's own photographs.
Sourced from the Canada Energy Regulator's damage prevention pages (prescribed area, consent thresholds, locate requests) and its notice of the Trans Mountain Salmon River Replacement Project (360 metres, seismic hazard, Belmont Golf Course to Forest Knolls, Glover Road crossing, application May 2024, construction anticipated Q2 2025), Trans Mountain's Lower Mainland construction pages (Spread 7A, 232 Street to the Fraser River crossing), the Township of Langley's Trans Mountain Pipeline page (2019 route submissions; Davidson Creek, Salmon River, Yorkson Creek; aquifers, roads, parks), Trans Mountain's community benefit announcement for the Township, and the Fraser Valley Real Estate Board's August 2026 figures read through InfoSparks (September 2026 report), all read 16 September 2026. This report describes and informs; the registered right-of-way document and plan for a specific lot are what your lawyer reads, and we help you get them before you offer. Do you know whether the lot you are considering is crossed by the strip, inside the 30-metre band, or clear of both?
