The Cord Rule: What Measurement Canada Requires a Firewood Seller to Deliver

A pile in a driveway cannot be measured. That follows from the definition, which is written around wood piled regularly with its axes roughly parallel. Until the wood is in that condition, no measurement of it means anything.

The difference is larger than most people expect. The Woodlot Association of Manitoba puts the loose-to-stacked ratio at roughly 180 cubic feet of thrown wood for every 128 cubic feet of stacked cord — an expansion of about 1.4 times. A heap that looks impressively large can be well short of a cord, and a thin-looking heap can be a full one. Eyeballing produces confident wrong answers in both directions.

Building a stack that measures

Stack in a straight row on level ground, pieces running the same direction, ends aligned as closely as the wood allows, touching rather than crossed or bridged. Keep markedly different lengths in separate rows, because the width of a row is taken from the average piece length and mixing lengths makes that average meaningless.

Two things do the most damage: crooked or forked pieces holding the row open, and deliberate crossing or "log-cabining," where pieces are laid at angles to inflate the stack. Both add volume without adding wood. If you can see daylight through the row in several places, restack that section before measuring.

Taking the measurement

The Nova Scotia Department of Natural Resources sets out the method, and it is the part most buyers get wrong. Mark points along the row at intervals of no more than five feet (1.5 m). Measure the height at the mid-point of each interval and average those heights rather than using the tallest point or an end. Take the width from the average piece length, measured at least once per interval. Length times average height times average width gives the volume of the row.

Shape is irrelevant. Four feet high, four deep and eight long is a cord; so is four feet high, two deep and sixteen long. Both occupy 128 cubic feet, and that is the whole of the requirement. Inside that volume sits roughly 73 cubic feet of solid wood, 40 of air and 15 of bark — the air is written into the definition, which is why this measures stacked wood rather than timber. Where the stack goes afterwards is a separate decision that overlaps with wood stove and fireplace safety more than most buyers expect.

Converting to the legal unit

Every conversion below rests on one assumption, and it does all the work: the piece length. A face cord is eight feet by four feet by the piece length, so the piece length is not a detail of the calculation — it is the calculation.

Three of those worked in full. At 16 inches: 16 ÷ 12 = 1.33 feet, so 8 × 4 × 1.33 = 42.7 cubic feet, and 42.7 ÷ 128 = 0.33 of a cord. At 12 inches: 1.00 foot, so 8 × 4 × 1.00 = 32.0 cubic feet, and 32.0 ÷ 128 = 0.25. At 14 inches — a common real-world average when a seller cuts to suit a range of stoves — 14 ÷ 12 = 1.17 feet, so 8 × 4 × 1.17 = 37.3 cubic feet, and 37.3 ÷ 128 = 0.29.

To reach the metric unit, divide cubic feet by 35.3, the federal equivalence for one stacked cubic metre. That is why a cord is 3.63 stacked cubic metres.

Firewood is a named category in the federal measurement complaint system, listed alongside gas pumps, retail scales and draft beer measures, and Measurement Canada inspects bulk firewood as a net quantity much as it inspects deli meat and propane refills.

It is also candid about the limits. The agency states that it "does not: negotiate any compensation" and does not usually process anonymous complaints. A complaint asks for your name and contact details, the seller's name and address, and information on how you have already tried to resolve the matter — which makes contacting the seller first a practical precondition rather than a courtesy. What it produces is an investigation and a communicated result. What it does not produce is your money back.

That distinction matters more than anything else in this section. The federal route corrects the market; recovering value from one transaction is separate, pursued with the seller directly or through small claims in your province.

Ontario

The provincial route runs through the ministry responsible for consumer protection and begins with the same precondition: advise the business first, by letter, email or telephone. Filing is free, online, by mail or by email, with supporting documents — correspondence, the order confirmation, invoices, payment records. The ministry commits to contacting you within 15 business days, and may refer, mediate, educate, issue compliance orders, investigate, or add a business to the Consumer Beware List for repeated violations. It cannot help where the transaction is more than two years old, where it was business-to-business, or where you seek damages beyond a refund or cancellation.

Quebec

The Office de la protection du consommateur takes complaints by telephone, online or in person, checks admissibility, and enters an admissible complaint in the merchant's file — which feeds reminder notices, non-compliance notices, administrative fines or recommended penal proceedings depending on severity and history. The Office is explicit that its "personnel cannot intervene on your behalf to correct the situation". It will ask for the invoice, the contract and any written terms, and points to a formal demand letter as the step preceding all of this.

British Columbia

British Columbia is worth knowing about before you spend an afternoon on it. Firewood is not among the sectors Consumer Protection BC regulates — its published list runs from cemeteries and credit through payday loans, home inspections, travel and door-to-door sales to film ratings — and the organization notes that "BC consumer protection laws may not apply to your situation" and that you may need another organization or the courts. For a BC firewood measurement dispute, the federal route is the route, unless the sale happened to be made door-to-door.

Everywhere else

Nothing found at the provincial or municipal level adds a firewood-specific measurement standard on top of the federal one. Provincial material on firewood volume, including the Nova Scotia circular used earlier, restates the federal definition rather than imposing a separate standard. Where the federal guidance is silent — on what counts as an acceptable settling allowance, for instance — it is genuinely silent rather than deferring to something local.
