📊 Where the data comes from
For a decision tool to be credible you need to know where the numbers come from. Here are all our sources.
Fuel prices
Régie de l'énergie du Québec — public GeoJSON feed
regieessencequebec.ca · CORS open · updated live by stations
- 2,461 active Quebec stations
- Fuels: Regular, Super, Diesel
- Price coverage: ~98% Regular, ~85% Super, ~90% Diesel
- Our cache: 5-10 min server side, direct re-fetch on client
EV charging
City of Montréal — public EV chargers
Official open dataset · CC BY 4.0 · monthly updates
Preferred source within Montréal. InfoGas groups ports at the same location into a site while retaining the reported port count.
NLR / Alternative Fuels Data Center
Official API · data use does not imply NLR or Department of Energy endorsement
Preferred province-wide source when configured. An operational status describes the known site, not a port that is free right now.
Open Charge Map and its data providers
Supplementary open source. Licences can vary by provider; InfoGas keeps record-level attribution and removes obvious duplicate locations.
Not live occupancy: confirm current status, pricing and connector in the network app before travelling.

Proprietary calculations
The net-after-cards values (RBC × Petro-Canada, CAA × Shell, PC Optimum…) are our interpretation of each program's public terms. Indicative — the actual conditions remain those of each issuer and may change. See our card matrix for verification dates.
Detour costs assume urban average speed 35 km/h, a 1.4× factor between straight-line and road distance, default consumption 8 L/100 km (overridable in profile), default time value $20/hr.
Errors and corrections
A price looks wrong? A station missing? Email bonjour@infogas.ca — we forward price corrections to the Régie who must validate with the merchant.
