There is a difference between the way things worked beforehand and what we are going to do in the future. Changes have been made. For example, on March 2, there were two security perimeters; one at the lower drive and the other at the top drive. However, we had to eliminate the lower drive perimeter so that people could get to the five access points located at the top of the Hill. Now, once you have crossed one of these access points, depending on where you are, you will be able to continue. If you wish to go to Centre Block, you could continue and have access to the building.
