Almost every grocery will have a vegetable shortening based product. As eatrustic points out Super Store sells it. The PC label puff pastry made with butter is actually pretty good. The No Frills stores carry many PC items and might have this too.
Whole Foods in our area sells the Dufour brand which is all butter. I thought it was fairly expensive. (I'm sure it is wonderful with all butter though) Most grocery stores sell the Pepperidge Farms veg/short version .AsWhole Food is 40 min away I tend to use that version.
