For the homeowner who already heats with propane and is sizing up their supplier, and for the homeowner just stepping into propane — a new rural property, a new build off the gas grid, a switch from oil or electric. The page below walks through how residential propane actually works in this part of the province: the tank, the delivery, the setbacks, the codes, and the honest version of what happens on the rare occasion a tank does run dry.
A short orientation for the reader who is new to propane, and a quick read-through for the reader who already knows it. The four moving parts of a residential propane account, named in the order they show up.

Three tank shapes cover almost every residential propane account in southwestern Ontario. Past that, tanks at 2,000 USWG and up are commercial or agricultural and live on a different conversation. The ranges below are estimates — actual consumption depends on insulation, thermostat setpoint, weather, and how the home is actually used. The supplier’s job is to right-size the tank to a specific home, not to apply a formula.
100 USWG. The Canadian standard for a moderate residential load — typically a propane water heater, a range, and a dryer in a home heated some other way. Manifolded pairs are common on cottages and small backup setups. Not a primary-heat tank for most homes in this part of the province.
The standard primary-heat tank for SWO rural homes of 1,500–3,000 sq ft. The horizontal cylinder is set on a pad with the required setbacks; the regulator and line set carry propane from the tank to the appliances. Two to four fills a year on a well-sized account.
For larger rural homes — older farmhouses with extensions, recent rural builds at 3,500+ sq ft, or homes with heavy ancillary loads (pool heater, generator, multiple propane appliances). The same horizontal-cylinder shape as the 500, set on a larger pad with the larger setback from the structure.
Minimum 10 ft (3 m) from the nearest building, from the property line, from any ignition source, and from a mechanical air intake — including heat-pump and air-conditioner condensers. Most 500 USWG residential placements settle into a corner of the lot a reasonable walk from the truck access; the contractor walks the property at the assessment to confirm the position.
Minimum 25 ft (7.5 m) from the same list. The larger setback is the structural reason most residential accounts run a 500 USWG tank rather than a 1,000 — a 1,000 needs a lot that can give it 25 ft of breathing room. On rural lots that is rarely a problem; on smaller suburban lots it can rule out the larger size.
Underground tanks at 250 to 1,000 USWG are a real option on properties where the homeowner prefers the look or wants the tank out of the snow. The setback to the building drops to 10 ft for tanks up to 2,000 USWG, but stricter rules apply near septic fields (10 ft) and private wells (25 ft for tanks under 2,000, 50 ft for larger). Underground tanks cost more up front and carry an anode-bag check on a periodic cycle, but they handle winter better and stay out of sight.
New propane service starts with a site walk — the installer and the supplier rep confirm where the tank can sit, where the line will run to the house, how the truck will reach the fill point on a deep-snow morning, and whether the lot supports the size of tank the consumption math points at. The homeowner does not have to read the setback table; the assessment is what translates the rules onto the property.
Any underground propane line is buried at 18 inches minimum (24 inches under a driveway), routed without right angles, and kept clear of other utilities. Ontario One Call is the no-cost locate service that flags existing buried utilities before any digging — the call goes in three working days before line work starts. The contractor handles it; the homeowner sees the locate markings on the lawn the morning before the trench opens.
A practical breakdown of the three ownership models. Most prospects do not know this is a choice at all; most accounts settle into one of these at the new-service conversation. B&J supports each one. The honest version of the trade-offs is below the model name.
The supplier owns the tank; the homeowner pays for the propane that goes into it. The tank-side maintenance — the regulator, the gauge, the periodic inspection on the supplier’s side of the line — is the supplier’s responsibility. No up-front cost. The catch: switching propane suppliers later means swapping the tank, which is a logistical step and usually a small cost to the homeowner. The contract is one-year supply, not five-year exclusivity.
The homeowner buys the tank outright at install and is free to compare propane suppliers without a tank swap getting in the way. Up-front cost runs in the $2,000–$5,000+ range depending on size, aboveground vs. underground, and what the lot needs. No annual rental fee. The trade-off: maintenance and eventual replacement are the homeowner’s cost when the tank gets old enough that it needs work.
A middle path that some suppliers offer: the homeowner makes payments toward eventual ownership of the tank over a defined term, often five to ten years. Less common in Ontario than either of the other two models, and not every supplier offers it. The trade-offs land between supplier-owned and customer-owned — smaller up-front cost than buying outright, eventual ownership at the end of the term.
After the first two or three deliveries, the supplier’s dispatch software has a stable K-factor for the home — litres consumed per heating degree-day. From there, the system runs daily, accumulating degree-days against the K-factor, and estimates current tank level without anyone reading the gauge. Newer accounts run on a conservative K with extra slack; long-tenured accounts run on a tighter K because the data underneath it is better.
The truck is scheduled when the estimated tank level drops into the 20–25% range — well above empty, with enough margin for a weather delay or a route shuffle. On most residential accounts the homeowner sees the truck arrive a few days before they would have noticed the tank gauge was getting low. The whole point of auto-fill is to make the question of "how much is left" something the homeowner does not have to ask.
The K-factor assumes the house keeps using propane the way it has been. A new high-efficiency furnace, a thermostat set 4 °F lower than last winter, a new occupant, a new pool heater, supplemental wood heat in the basement — any of these shifts the K-factor, and the schedule needs to catch up. A short call to the named rep is what catches it; the dispatch system can recalibrate after one or two deliveries on the new pattern.
A southwestern Ontario January-February stretch of –15 to –25 °C nights is the residential propane business’s working season. The standing route runs through it with extra capacity on hand; trucks move on schedule; existing accounts get priority over new sign-ups for fills that week. The supplier’s job is to make the deep cold a non-event for the homeowner — the schedule was built to absorb it.
Honest version: every propane supplier in the industry has run a tank dry at some point, and we have too. The leading causes are a sudden consumption shift the K-factor has not caught up to, a customer on will-call who watched the gauge drift past empty, a deep-snow week that delayed a truck, or a communication breakdown on a new account. The route and the dispatch software are built to prevent the next one — and when one does happen, the after-hours line answers and a truck rolls to restore service. The path from "tank empty" back to "house warm" is the test of the supplier-customer relationship, and the right answer is short.
Residential accounts are typically billed per delivery — the litres pumped at that day’s posted residential rate, plus HST. Equal-monthly billing programs are available on long-term accounts where the seasonal swing in the bill matters less to the household than the predictability of a level monthly amount. Pricing is shown on every delivery invoice; the components are visible.

A named rep takes the call, not a queue. Tell us where the house is, what the propane situation is now (existing supplier, new build, new property), and what you are trying to settle. We can usually settle the supplier question, the tank-sizing question, and the next-step question in one conversation.
Standing routes across nine regions. Same rep year-round; off-hours emergency dispatch through the same number.
