I'm going to talk at a high level to a certain extent.
First, there's a layered approach. Every building sits within a broader security perspective.
Over the past number of years, efforts have been made to create greater security around the movement of vehicles, for example. The vehicle screening facility and bollards have been implemented.
Phase one of the visitor welcome centre is all about ensuring that the public goes through proper security screening. Phase two of the visitor welcome centre will apply that to the Centre Block and the East Block as a critical security initiative.
Cameras are also integrated throughout the facilities, as well as controls on doors to ensure that those can all be managed and locked down as required. There are control points at all of the exterior doors in facilities such as the West Block.
Then we look at elements such as hardening the building as required, ballistic in some areas, as well as efforts at cybersecurity and speech security to ensure that if you are having a private conversation in a room, it is indeed a private conversation.
All those elements, which previously didn't exist in the Centre Block, will be applied as we move forward in its modernization.
