I'm a big believer in property rights, and I have real concerns with expropriation powers. To give a crown corporation the power to expropriate would cause me great concern.
Going back to the fifties, there are still some raw feelings from people and descendants of families who had their land, farm, or home expropriated when the greenbelt was created. I'm very, very cautious on expropriation powers for a crown corporation. If in extraordinary times a contractual agreement can't be reached, I suppose that's always something to be considered, but to give it to a crown would cause me concern.
