Canola oil is 100% plant-based. It comes from the seeds of the canola plant, a member of the same family as broccoli, cabbage, and mustard. No animal products are used in growing, extracting, or refining it, making it compatible with vegan, vegetarian, and any other plant-based diet.
Where Canola Oil Comes From
Canola oil is pressed from the seeds of Brassica napus, a flowering plant in the cruciferous family. The crop traces back to rapeseed, which was cultivated as an oilseed as far back as the 13th century. Traditional rapeseed oil had high levels of erucic acid and bitter-tasting compounds called glucosinolates, which limited its use mostly to industrial applications like lubrication.
In the 1970s, Canadian plant breeders used conventional crossbreeding to develop new varieties with less than 2% erucic acid and dramatically lower glucosinolate levels. The first of these “double-low” cultivars, called Tower, was released in 1974. These new varieties were safe and palatable enough for cooking, and the crop got a new name: canola, short for “Canadian oil, low acid.” Canada’s food inspection agency formally classifies canola oil as a vegetable oil produced from the seeds of approved Brassica species.
How Canola Oil Is Made
The production process is entirely mechanical and chemical, with no animal-derived inputs at any stage. After harvest, the seeds are cleaned to remove soil and debris, then crushed into smaller pieces. These pieces are heated and pressed in an expeller press, which squeezes out the raw oil and leaves behind a dry press cake.
That first pressing doesn’t get all the oil out. The leftover press cake is broken into flakes and mixed with a solvent called hexane, which draws out the remaining oil. The mixture is then heated so the hexane evaporates and can be collected for reuse. If you’re wondering about hexane residues in the finished product, the European Union sets a maximum limit of 1 mg/kg. Studies of commercial vegetable oils consistently find levels far below that threshold, typically in the range of micrograms per kilogram (thousands of times lower than the limit).
The combined oil then goes through refining: an acid wash (usually citric acid) removes certain compounds, bleaching clay absorbs color pigments, and a deodorizing step strips out volatile flavors. The final product is a neutral-tasting, light-colored oil ready for bottling. Every ingredient in this chain, from the seeds to the citric acid to the bleaching clay, is non-animal.
Nutritional Profile
Canola oil is notably low in saturated fat compared to many cooking oils, at roughly 6 to 8% of its total fat content. The bulk of its fat is monounsaturated, around 60 to 65%, with polyunsaturated fats making up the remaining 30 to 35%. One tablespoon provides about 9 grams of monounsaturated fat, 4 grams of polyunsaturated fat, and roughly 1 gram of alpha-linolenic acid, a plant-based omega-3. You’ll also get about 2.4 mg of vitamin E per tablespoon.
That omega-3 content is worth noting for people on plant-based diets, since good plant sources of omega-3s are relatively limited. Canola oil won’t replace fatty fish or algae supplements for the longer-chain omega-3s your body needs, but the alpha-linolenic acid it provides is a useful building block your body can partially convert.
Cold-Pressed vs. Conventional Canola Oil
Both versions are plant-based, but they differ in processing. Cold-pressed or expeller-pressed canola oil skips the hexane extraction step entirely, relying only on mechanical pressure. This appeals to people who prefer minimal processing. The tradeoff is a slightly lower yield and higher price. Refined canola oil, the type most commonly sold, goes through the full extraction and refining process described above. It has a neutral flavor and a smoke point of about 204°C (400°F), which makes it practical for frying, roasting, and baking.
GMO Considerations
Most commercially grown canola is genetically modified for herbicide tolerance. The first transgenic herbicide-tolerant canola varieties received regulatory approval in Canada in 1995, and adoption spread quickly. If you follow a plant-based diet and also want to avoid GMOs, look for certified organic or non-GMO verified canola oil. The oil itself is plant-based either way, since genetic modification involves altering the plant’s own DNA rather than introducing animal genes. But for shoppers who care about both labels, organic canola oil satisfies both criteria.
Where It Fits in a Plant-Based Diet
Canola oil works well as an everyday cooking oil for people eating plant-based. Its high smoke point handles sautéing and stir-frying without breaking down. Its neutral taste won’t compete with other flavors in dressings or baked goods. And its fat profile, low in saturated fat and relatively high in omega-3s for a cooking oil, aligns with the nutritional priorities many plant-based eaters have. For finishing dishes or salads where flavor matters more, olive oil or other specialty oils might be a better choice, but canola fills the role of a versatile, affordable, all-purpose plant oil.
