An evaporative-emissions code. EVAP codes don't affect drivability — they mean the system that captures gasoline vapors from your fuel tank isn't sealing or flowing the way the computer expects. In Canada, where fuel cap and vent-solenoid issues are very common in winter, start with the fuel cap before paying for diagnostic time.
Causes are listed roughly in order of how often they're seen on Canadian independent-shop tickets. Always confirm with a scan-tool freeze-frame and a circuit/sensor check before replacing parts.
