Vegetable oils have a lower flash point than olive oils, canola/rapeseed are much better and healthier than partially hydrogenated oils such as soybean, cottonseed or corn. Canola oil is also an unsaturated fat that’s high in omega-3 fatty acids. There are claims that when canola oil is heated above 120°F some of the fatty acids turn to trans fats.

Just watch that lower flash point, it'll smoke and catch fire more easily than other oils at high temperatures.
