To a small skillet, add canola oil. Heat the skillet on medium heat.
Add a tiny piece of a tortilla to the oil, when it starts to bubble, using cooking tongs, add a tortilla to the oil; hold up one side (half of the tortilla) out of the oil to form a taco shell.
After the side of the tortilla in the oil turns golden, using your tongs, turn the tortilla over to cook the other side.
Then, cook it until that side is also golden. Transfer the taco shell from the pan onto a paper towel-lined plate. Repeat the cooking process for the remaining tortillas.
