Preheat oven to 375°F.
Put the butter, brown sugar and syrup into a parchment-lined or buttered 8x8-inch pan.
In a medium bowl, combine the flour, baking powder and salt. Add the milk and canola oil and stir just until you have a soft dough. Pull out the pan and stir the melted butter, brown sugar and syrup together with a fork.
On a lightly floured surface, pat or roll the dough into about a 9 x 12-inch rectangle. Sprinkle with brown sugar and drizzle with syrup. Sprinkle with cinnamon. Starting from a long side, roll tightly jelly-roll style into a log. Cut into 9 biscuits using dental floss or a serrated knife, and place cut side down in the pan.
Bake for 20 minutes, until golden and bubbly. Invert onto a plate while still warm.
