Preheat the oven to 350 degrees F. Grease a 9x5 inch bread pan.
Whisk together the pumpkin puree, canola oil, eggs, vanilla, and brown sugar in a medium bowl until smooth. Stir in the flour, baking powder, pumpkin pie spice, and salt until just combined. Pour the mixture into the prepared bread pan.
Transfer to the oven and bake for 50-55 minutes or until the top is lightly golden and a toothpick inserted into the center comes out clean. If the top is browning before the center of the bread is done cooking, cover with foil.
