This 431-mile drive crosses into Canada 279 miles after leaving Boston, and a typical car that starts full needs one fuel stop: Vaudreuil-Dorion, QC (335 miles in). A truck towing a trailer, at about 253 miles a tank, needs two: South Burlington, VT (215 miles in) and Ottawa, ON (427 miles in), the last only to keep the 15% reserve on arrival.
The longest stretch without a station within 2 miles of the road is 24 miles, from Rigaud, QC to 13 miles before Saint-Isidore, ON. Stations in Canada sell fuel by the litre (a US gallon is 3.79 litres). The road is 38% longer than the straight line between Boston and Ottawa (313 miles).

|---|---|---|---|

| 2 | Petro-CanadaOttawa, ON | 427 mi | 15% |
Arrive in Ottawa with about 98% of the tank.
Both plans leave Boston with a full tank, keep 15% in reserve, fill up completely at each stop and prefer stations in or near towns, as Fillerup does by default. Stops are chosen from stations within 2 miles of the route.
Driving back: Ottawa to Boston
The drive back from Ottawa to Boston is 429 miles, 2 miles shorter than the way there, and its longest stretch without a station within 2 miles is the same 24 miles, between 13 miles past Saint-Isidore, ON and Rigaud, QC. The stops fall in other places, because the plan starts with a full tank in Ottawa:

No stretch goes 45 miles or more without a station within 2 miles. A station missing from OpenStreetMap would make a stretch look longer than it is, and a mapped station may have closed, so treat these as a guide.
Stations along the way
OpenStreetMap lists 501 stations within 2 miles of this route. 232 of them are in the Boston and Ottawa areas; of the 269 in between, the most are in Manchester, NH (36), South Burlington, VT (16) and Montpelier, VT (15).
404 of them have a brand in the data; the most common are Mobil (75), Shell (53) and Sunoco (33).
26 are tagged as open 24/7. Stations without that tag may still be open around the clock: the data can't tell.

How this page was made
- Route: from the centre of Boston to the centre of Ottawa and back, each direction routed on its own, by Geoapify routing (fetched November 12, 2026). Fillerup asks for the route again when you open the trip, so its numbers can differ a little.
- Stations: every usable fuel station in OpenStreetMap within 2 miles of the route (private, disused and truck-only ones left out), from Fillerup’s station data as of November 11, 2026.
- Stops: Fillerup’s own planner, with the two vehicles above, each way from a full tank. Its picks favour stations in towns over isolated pumps, so a stop can come earlier than the tank strictly needs.
- The Boston and Ottawa areas: within 47 miles of Boston and 45 miles of Ottawa, the distance within which Fillerup’s route selection counts a city as part of the metro (it grows with the metro’s population), leaving out places nearer another metro’s centre or across a border.
- Not covered: fuel prices, opening hours beyond the 24/7 tag, road conditions, closures and detours.
