Yes. However, you have to understand that the concept does not apply in cases where the access problem is caused, say, by a traffic light. If a member could not get onto Parliament Hill because a traffic light was red, I assume that it could not be seen as a matter of privilege.
Moreover, if a system of security has been put in place for parliamentarians and parliamentary staff has been assigned to it, and certain incidents inconvenience parliamentarians, it is certainly unfortunate, but would it really be a matter of privilege? That is quite a complex question that you must answer. There are a number of factors to consider.
My role is more to ask questions than to provide answers.
