In our real estate operations, as I mentioned before when the member for Brampton East made a statement, most of the land we're acquiring is vacant. When we're acquiring property, environmental testing is done so that there is an understanding of any environmental conditions within the soil. Where there are buildings we are acquiring, there are also building assessments to identify whether there are liabilities on that basis.
The comfort and the confidence we have is that the actual removal or cleanup of building materials or contaminants in the soil are understood, and will be managed through the redevelopment of the project, which is not unusual or a discomfort that real estate developers have.
