Yes, a bit, but it's important to mention that the parking lots for people who drive are still fairly close to the National Assembly. They aren't necessarily on the National Assembly grounds, but they are still fairly close. Parliament Hill is very well covered by security camera systems. The area around Parliament is really very secure. Indeed, someone who leaves the premises at two in the morning, when the streets are deserted, may have some concerns, but as far as I know, no MNA or staff member has had any unfortunate incidents in the area.
