Which type of bond is found in many carbon-to-carbon bonds in canola oil, but very few carbon-to-carbon bonds in butter?

Canola oil is mostly unsaturated fat, meaning many of its carbon chains contain carbon-to-carbon double bonds. Butter is mostly saturated fat, which has very few carbon-to-carbon double bonds. Therefore, the bond described is C=C, a carbon-to-carbon double bond.
