Preheat oven to 475°F if using a baking sheet or pizza pan or to 500°F if using a pizza stone. Place the pan in the oven while the oven preheats.
Whisk together 1 cup flour, yeast, sugar and salt in a large bowl. Add oil to the water and pour into dry ingredients. Stir until well blended, about 1 minute. Gradually add enough remaining flour to make a soft dough.
Dough should form a ball and will be slightly sticky.
Knead dough on a floured surface, adding additional flour if necessary, until smooth and elastic, about 4 minutes.
Cover and rest the dough for 10 minutes.
Stretch and pat dough with floured hands to desired size (makes a 12-inch pizza). Assemble the pizza on parchment paper for easy transfer to the hot pan.
Spread with pizza sauce. Top with cheese. Spread Canadian bacon, bacon, and pineapple over the top.
Carefully transfer the pizza on the parchment to the heated pan. Bake on lowest oven rack for 10 to 15 minutes, until cheese is bubbly and crust is browned.
Cool just a minute or so before slicing and serving.
