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 [email protected] — we forward price corrections to the Régie who must validate with the merchant.
