Is it possible for canola oil to become bad?
Canola oil, like other oils, degrades with time. Even though mold or rot are very unlikely to develop, spoiling will occur over a period of time. The biggest difficulty with canola oil spoilage is that it is readily rancid. When oil molecules are exposed to air, light, or heat, they get oxidized, resulting in rancidity.
Consumption of oxidized lipids is not only unpleasant, but it may also be harmful to your health, thus consuming rancid oil is highly prohibited. To ensure that your cooking oils last as long as possible, proper storage is essential.
Check for any odd odors to see if your canola oil has deteriorated. When canola oil gets rancid, it emits an unpleasant odor, much like all other oils. Check for rancidity by smelling the oil in the container before preparing any food. You don’t want to pour oil over those veggies just to discover it’s gone rancid too late!
As the oil starts to degrade, there may be color changes as well. If you discover that your oil has darkened, you should definitely do a rancidity test.

Canola Oil Storage
Canola oil should be stored in a cool, dark place in a tightly sealed container. It’s important that the oil has minimal contact with light, heat or oxygen to slow the oxidation process, and so Canola Oil Storage next to the stove is highly discouraged. If properly stored, an unopened bottle of canola oil will have a shelf life of around two years, though depending on storage conditions, it is possible for the oil to go rancid is less time, so checking your oil before each use is important. Keep in mind that the oil will have likely been on a store shelf for a while before arriving to your kitchen.
Because of the exposure to air after a bottle of canola oil is opened, the shelf life reduces to six months to a year, depending on storage circumstances. Refrigerating the oil will keep it from becoming rancid as rapidly, but it will only last a year.
It’s not a good idea to freeze canola oil since it won’t keep for more than a year. Furthermore, freezing the oil changes its structure, causing it to grow rancid much more rapidly once it thaws.
Look for canola oil that is housed in a dark glass container or a canister while shopping. Both of these storage solutions drastically minimize light exposure. If your canola oil container is made of transparent glass or plastic, keep it away from light and heat.
