Usually, it is not essential in the function of the engine. It serves more of an environmental protection purpose and has as slight use in improving fuel mileage. Without the canister, the fuel system can vent some fuel vapors directly to atmosphere (not very enviro-friendly and wasting fuel) instead of storing them for reintroduction into the fuel system.

If you included the kind of car you have,I could be more specific but all cars have a vacuum canister under the hood. some are round plastic and some are a tin can and most are black. There shuold be a vacuum line going from the intake to one end and a vacuum line out of the other that supplies vacuum to the interior of the car, There should be a one way valve in the canister or the line from the intake. This valve is not functioning and loosing vacuum in the resirvoir. If it is in the resirvoir which most are, replace the resirvoir.
