Preheat oven to 350ºF (190ºC) and line cookie sheets with parchment.
In a large bowl, beat canola oil with sugar. Whisk in egg and molasses.
In a medium bowl whisk together flour, candied ginger, ground ginger, cinnamon, cloves, baking powder, baking soda and salt.
Add flour mixture to canola oil mixture and stir until dough is moist. The dough can be quite sticky.
Using a 1 tsp (5 mL) self releasing scoop and your hands, shape dough into a ball. Roll in sugar. Bake on prepared sheets in the preheated oven for 10-12 minutes. Let cool on cookie sheets or racks.
Chocolate Dip
In a saucepan over low heat, add chocolate and oil, stirring until chocolate is melted and mixture is smooth.
Dip half of each cookie in chocolate mixture.
Place on parchment or waxed paper and set aside until chocolate hardens, about 1 hour (or place in refrigerator to speed up hardening).
