Pour canola oil and 2-3 kernels popcorn into a large sized pot with tight fitting lid. Place over high heat on stovetop. When the 2-3 kernels pop, pour in the remaining kernels and move pan around over heat until all of the popcorn has popped.
In a small bowl, mix agave nectar, cinnamon and salt. Pour mixture over popcorn in pan and toss with hands or wooden spoon. Lay popcorn out on baking sheet and bake in a preheated 375-degree oven for 10 minutes.
