Lightly spoon flours into dry measuring cups; level with a knife. Combine flours, baking powder, baking soda, and salt in a large bowl, and make a well in the center of the mixture. Combine buttermilk, eggs, and 1 tablespoon canola oil in another bowl; add to flour mixture, stirring until smooth. Spoon about 1/4 cup batter on a hot griddle lightly coated with some of remaining oil. Turn pancakes when tops are covered with bubbles and edges look cooked. Cook another 2-3 minutes or until done. Continue with remaining batter and oil.
