Canola is scientific creation ( Created by CANADA! )
This is a bit of a pet peeve of mine so please forgive the rant... "Canola" is "Can"ada "ola" (oil) i.e. it does not exist in nature - at least not naturally.
I generally like Canada but whenever I see canola I think of the disdain Eveylyn Waugh wrote of the "Canadian" in my favorite novel of all time, Brideshead Revisited. (classless profiteer ruining the world)
In my lifetime I've watched all these products claim to be better for you than natural products i.e. margarine is better than butter, diet soda is better for you than regular, fat is bad, carbs are bad, eggs are bad, red meat is bad etc etc but at the root of them is always someone profiting off something else and then people getting sick or suffering other maladies as a result.
Canola is created genetically mutating rapeseed ("rapeseed" not grapeseed). Rapeseed is a very cheap oil used for lamp oil other industrial uses and was deemed by several governments not for human consumption. Resourceful Canadians modified it to create a cheaper food oil and gave it a name a lot easier to market. Seems like a bad idea to me so I have avoided it for years.
In my home I stock grapeseed oil, olive oil, peanut oil and sesame oil and this will get me through pretty much every usage. Occasionally I'll buy something different. I can substitute grapeseed for just about anything but for deep frying I will use peanut. Sesame mostly for Asian recipes and Olive for specific recipes /dressing. The only other oil that I use with some regularity is flaxseed oil to do an involved process of bonding a non stick surface to my cast iron.
I've noticed Walmart is regularly stocking Oliveri 100% grapeseed oil now at a good price. Costco version is not good / deceptive. It is 50/50 grapeseed/canola but the label on first glance just looks like "Grapeseed" so that ticks me off... But they do carry the huge restaurant size jugs of peanut oil but usually only sell them around Thanksgiving I suppose for those people who deep fry turkey. I buy those and transfer some to smaller containers for regular use. TJs usually has 100% grapeseed.
