That being said, just came across a better deal if you don't mind driving a bit for people outside of the GTA.
National Tire at 1277 Caledonia, just south of the 401, has quoted me better prices.
$866 via Ford Quick Lane vs $800 National Tire for 4x BF Goodrich Sport Comp-2 summers (225x45x17) that's balanced, installed, including taxes.
