well theres so many names for it....roll out fondant, sugarpaste etc.
i ahve no idea what they sell in canada, so cant really suggest a certain make....but have u heard of Renshaws Regal Ice? you might be able to get your hands on that.
you just knead it like you would with dough till its really pliable n slightly warmed by your hands, then just roll it out and pop it onto you cake!!! smoothing round with your hand as you go trying to 'iron' out any bumps
