Place roast fat side down in a shallow metal pan or iron skillet.
Rub all surfaces of the roast with canola oil.
Combine all the dry ingredients together to make a rub. Note: I mortar and pestle the rosemary a little to break it apart and release the flavor. You can use more or less of these dry ingredients to taste or to your perference.
Apply the above to all surfaces of the roast. Rub them in well and return the roast to the pan fat side down.
Drizzle maple syrup over top of the roast and let it run down the sides. Try to coat the top and sides evenly. It's okay if the syrup runs down onto the pan surface.
Bake in a preheated 325F oven. Refer to a cookbook pork roasting chart to determine the exact baking time, depending on the weight of your roast. A 2 1/2 to 3 pound roast should take about 1 hour and 20 minutes to be done in a 325F oven.
After the roast is done, remove from the oven and let it rest for about 20 minutes or so while still in the pan. Then use a tablespoon to gather the thick fluid (glaze) from the bottom of the pan and spoon it over the top and sides of the roast.
