Here’s a great article from the Nutrition Source discussing these concerns head on. TL;DR

Given the above information, is commercially processed canola oil harmful?

Although care must be taken in handling and processing of canola oil and other vegetable oils, canola oil is a safe and healthy form of fat that will reduce blood LDL cholesterol levels and heart disease risk compared to carbohydrates or saturated fats such as found in beef tallow or butter.  Indeed, in a randomized trial that showed one of the most striking reductions in risk of heart disease, canola oil was used as the primary form of fat. [8] Whether using cold-pressed canola oil provides some small additional benefit is not clear.

In general, variety is a good strategy in nutrition, and thus consuming a variety of oils is desirable, for example using extra virgin oil when the special flavor is desired and canola oil or soybean oil for other uses. Both canola and soybean oils provide ω-3 fatty acids that are important to include in an overall diet.  Of course, avoiding overheating and burning of oils is important to provide the best taste and to avoid damaging the healthy-promoting fatty acids that they contain.
