Add the canola oil, peanut butter, syrup, salt, and pumpkin spice to a medium saucepan, and simmer for 8-10 minutes, stirring occasionally.
While the liquids are simmering, mix together the rest of the ingredients, in a separate bowl. Add the hot liquid to the dry mixture and mix well. On two foil-lined baking sheets, spread the granola evenly.
Put in the oven and bake for 40-50 minutes. Halfway through, stir the granola and spread it on the sheets evenly.
Let cool completely on the sheets, before storing in a container.
