CFS Fuel Field · Changed-Status Tracker

100LL Watch

What this tracks (and doesn't): each point reflects whether 100LL was listed in the FUEL field of one CFS edition — that's an airport's ability to sell 100LL (fuel tanks on the field), not real-time availability. A listed airport can still run dry temporarily; a delisted one may have gone empty long before its entry was removed. CFS entries are self-reported by operators and can lag what's actually happening on the ground. Transition dates are bracketed between the last and first confirmed editions, not necessarily the exact date the listing changed — see each case's precision for how tight that window is. And because historical coverage is uneven across airports and years, this is a list of confirmed changes only: the true number of Canadian airports that have lost or gained 100LL capability is almost certainly higher than what's shown here.

Fuel Availability

A snapshot, not a trend — every aerodrome's FUEL entry in the most recent national census (9 Jul 2026), independent of the change-tracking above.

The shrinking network

Average distance from a 100LL airport to its nearest 100LL neighbor, by province — measured at each of the three full national censuses (Dec 2020, Mar 2024, Jul 2026), since that's the only data with complete province-wide coverage rather than just the airports that changed. As airports lose 100LL, this number is what actually grows: how much further you have to fly to the next fuel stop. Click a province for its most isolated airports.

CWAS Fuel Field · Water Aerodromes

Water Aerodromes Watch

Every water aerodrome in the current Canada Water Aerodrome Supplement (CWAS), mapped by fuel type, plus how far apart the 100LL bases actually are, province by province.

What this tracks (and doesn't): each point reflects whether 100LL was listed in the FUEL field of the current CWAS edition — that's a base's ability to sell 100LL (fuel tanks on site), not real-time availability. FltPlan mirrors past CWAS editions under an older, page-numbered addressing scheme (discovered via a deep search of Google's index, not FltPlan's own search, which doesn't surface these) — reconstructed here across 30 reliable edition dates from mid-2021 to mid-2026, covering 398 idents. 8 show a confirmed, verified change in that window; the rest are steady across every date found.

8 confirmed changes

Reconstructed from FltPlan's archived CWAS pages across 30 edition dates (mid-2021 to mid-2026). Every case below is a single, clean transition landing exactly on a real CWAS annual-edition boundary — and cross-checked against the current supplement's own text.

Each dot is one confirmed transition, plotted at the edition where the change was first confirmed. All 8 are bracketed to a single AIRAC cycle — the tightest window the data allows.

Distance to the nearest base

Average distance from a 100LL water aerodrome to its nearest 100LL neighbor, by province — a single current snapshot, not a trend (see the note above on why). This is how far you'd actually have to fly to the next fuel stop if the one you're at didn't have it. Click a province for its most isolated bases.
