Suncor Energy Inc. v. The Queen, 2001 DTC 660 (TCC), aff'd 2002 DTC 7395, 2002 FCA 350 -- summary under Class 10

The taxpayer used the overburden and tailings produced or extracted by it in the process of extracting bitumen from oil sands deposits to construct dykes separating disposal areas from active mining areas, and deposited the balance of the tailings in the disposal areas. Notwithstanding that the dykes were 200 or 300 feet tall and were carefully engineered, Bell T.C.J. indicated that even if the expenditures on them were considered to have given rise to a capital asset, it was his "impression" that they could not be described as a "structure".
